Human Health Effects of Trichloroethylene: Key Findings and Scientific Issues

Abstract

Background

Background: In support of the Integrated Risk Information System (IRIS), the U.S. Environmental Protection Agency (EPA) completed a toxicological review of trichloroethylene (TCE) in September 2011, which was the result of an effort spanning > 20 years.

Objective

We summarized the key findings and scientific issues regarding the human health effects of TCE in the U.S. EPA’s toxicological review.

Methods

In this assessment we synthesized and characterized thousands of epidemiologic, experimental animal, and mechanistic studies, and addressed several key scientific issues through modelling of TCE toxicokinetics, meta-analyses of epidemiologic studies, and analyses of mechanistic data.

Discussion

Toxicokinetic modelling aided in characterizing the toxicological role of the complex metabolism and multiple metabolites of TCE. Meta-analyses of the epidemiologic data strongly supported the conclusions that TCE causes kidney cancer in humans and that TCE may also cause liver cancer and non-Hodgkin lymphoma. Mechanistic analyses support a key role for mutagenicity in TCE-induced kidney carcinogenicity.

Recent evidence from studies in both humans and experimental animals point to the involvement of TCE exposure in autoimmune disease and hypersensitivity.

Recent avian and in vitro mechanistic studies provided biological plausibility that TCE plays a role in developmental cardiac toxicity, the subject of substantial debate due to mixed results from epidemiologic and rodent studies.

Conclusion

TCE is carcinogenic to humans by all routes of exposure and poses a potential human health hazard for noncancer toxicity to the central nervous system, kidney, liver, immune system, male reproductive system, and the developing embryo/fetus.

Organic solvents and Multiple Sclerosis susceptibility

Abstract

Objective

We hypothesize that different sources of lung irritation may contribute to elicit an immune reaction in the lungs and subsequently lead to multiple sclerosis (MS) in people with a genetic susceptibility to the disease. We aimed to investigate the influence of exposure to organic solvents on MS risk, and a potential interaction between organic solvents and MS risk human leukocyte antigen (HLA) genes.

Methods

Using a Swedish population-based case-control study (2,042 incident cases of MS and 2,947 controls), participants with different genotypes, smoking habits, and exposures to organic solvents were compared regarding occurrence of MS, by calculating odds ratios with 95% confidence intervals using logistic regression. A potential interaction between exposure to organic solvents and MS risk HLA genes was evaluated by calculating the attributable proportion due to interaction.

Results

Overall, exposure to organic solvents increased the risk of MS (odds ratio 1.5, 95% confidence interval 1.2–1.8, p = 0.0004). Among both ever and never smokers, an interaction between organic solvents, carriage of HLA-DRB1*15, and absence of HLA-A*02 was observed with regard to MS risk, similar to the previously reported gene-environment interaction involving the same MS risk HLA genes and smoke exposure.

Conclusion

The mechanism linking both smoking and exposure to organic solvents to MS risk may involve lung inflammation with a proinflammatory profile. Their interaction with MS risk HLA genes argues for an action of these environmental factors on adaptive immunity, perhaps through activation of autoaggressive cells resident in the lungs subsequently attacking the CNS.

Anecdotal evidence has been emerging for some time of potential illness clusters at Casement Aerodrome to which Multiple Sclerosis has now been added. We are calling for these potential clusters to be investigated by competent authorities.

Suspected illness clusters currently include.

What did the British ever do for us? A fit for purpose solvent extraction system at Irish Air Corps!

The British Royal Flying Corps built a solvent exhaust stack at the now Irish Air Corps airbase at Baldonnel over 100 years ago. This exhaust stack stack featured a powerful fan for safely removing solvent fumes from a degreasing bath.
In the mid 1980s the Air Corps Machine Shop was moved to this location at the front of the ERF (Engine Repair Flight) building. To facilitate this move the “Trike Bath”, a heated trichloroethylene solvent vapour degreaser, was located to a new Non Destructive Testing (NDT) Shop to the rear of Engine Repair Flight (ERF). The 25 foot extractor chimney was replaced with an inadequate 6 inch fan which was ducted through a nearby window. 
Around 2006 an NDT technician in ERF turned yellow from jaundice due to a chemical induced liver injury. After the NDT technician turned yellow the officer in charge of Health & Safety ordered that the Safety Data Register and adverse air quality tests be destroyed.
The ERF building was condemned in September 2007, a fact that was denied in the Dáil by the former Junior Minister for Defence Paul Kehoe TD.
After some serving & former ERF personnel sought their medical files throught their solicitors in early 2008 the building vanished.

Trichloroethylene used to clean the floors in Irish Air Corps cookhouse!

Every now and again when investigating poor health & untimely deaths of colleagues in the Irish Air Corps at Casement Aerodrome we come across a cluster of unexplained deaths or illness in particular work locations.

Exposures are briefly explained by location below those in RED were unexplained until personnel came forward to highlight misuse of chemicals in these locations.

Apprentice Hostel

Exposure to asbestos was the main problem in the apprentice hostel and it does not appear to have been fully removed until the mid 1990s although some efforts were made to remove the bulk of it in the late 1980s. The 1990s effort used a professional removal service while the late 1980s effort used apprentices without any PPE whatsoever. Persistent black marks on lino or floor tiles would be dealt with by calling to the nearest hangar or workshop to borrow some MEK or Trike

Avionics, ERF & Parachute Shop

Illness & untimely deaths in Avionics Squadron and Engine Repair Flight (Engine Shop) can be explained by unprotected exposure to the chemicals used in both locations and by their exposure to exhaust fumes from the Spray Paint Facility. The Parachute Shop which was part of ERF establishment also used toxic glues and exposed personnel to fumes from PU coated drysuits.

Basic Flight Training School

Illness & untimely deaths in BFTS can be explained by the IRAN inspections where DCM/Phenol paint strippers were used without PPE and the extensive use (like in heli) of corrosion inhibitors like Mastinox. Of course the fuel for the Marchettis was leaded gasoline with its own issues.

Battery Shop

Illness in the battery shop can be explained by exposure to battery electrolytes & charging fumes. The personnel walking around here with holes in their jumper, trousers and shirts from sulphuric acid was almost comical if it wasn’t such a serious risk to their health.

Cookhouse / NCOs Mess

Until now we had not been able to satisfactorily explain the unusual body count & illnesses of personnel who served in the old cookhouse kitchen, new cookhouse kitchen and NCOs Mess kitchen.

Recently we were made aware of a practice in the old cookhouse as far back as the mid 1970s whereby personnel who worked there procured solvent degreaser from up camp. We believe this degreaser again to be trichloroethylene.

This solvent was provided sometimes in 25 litre drums and sometimes in gallon containers where it was usually decanted into smaller vessels like milk bottles or coke bottles to be spread on the floor and then mopped and squeegeed until the floor was spotless.

And it turns out that this practice continued in the new cookhouse and technicians from ERF who dropped down 25 litre drums of Trike were rewarded with a wrap up of some food like steaks.

We believe this floor degreasing practice occurred in the NCOS Mess kitchen but we have no evidence yet that it occurred in the Officers Mess Kitchen but given the fluidity of personnel movements between the various catering locations it is a distinct possibility.

Engineering Wing Hangar & Workshops

Illness & untimely deaths in Engineering Wing Hanagar can be explained by unprotected exposure to Paint Shop chemicals including isocyanates & thinners, Hydraulic Shop chemicals, Sheet Metal Shop chemicals, wood dust from the Carpentry Shop, welding fumes from the Welding Shop as well as paint stripper fumes and mastinox fumes from Marchetti IRANs or Alouette equivalent teardowns.

Fire Crew

Members of the fire crew would have had exposure to exhaust gasses of idling aircraft engines and would have also had exposure to fuel fumes  and burning fumes from training exercises. The Fire Crew also used PFAS based fire fighting foams.

Heli Wing

Illness & untimely deaths in Heli Wing are easily explained by unprotected exposure to the chemicals used maintaining helicopters, by exposure to fuel vapours from gravity refueling, exposure to exhaust gasses from gas turbine engines and the immune sensitisation capabilities of polyurethane coated immersion suits.  Toxic tubbing in Heli was also a thing.

Light Strike Squadron

Similarly illness & untimely deaths in Light Strike Squadron can be explained by unprotected exposure to refueling fumes, exhaust gasses and other lubricants, greases, hydraulic fluids and sealants used to maintain the Fougas. Toxic tubbing in LSS was also a thing.

Main Block

Illness & untimely deaths in the Main block can be explained by unprotected exposure to photographic film & printing chemicals. These photographic chemicals used in photo section drove death, illness & harm to offspring in personnel throughout the main block

Chemicals in use by workshops in Air Sp Coy Signals further exposed personnel in the mainblock to chemicals they would not have expected to be exposed to like trichloroethane etc.

Units exposed in the main block would include 

  • Admin Wing HQ
  • AE Section
  • Drawing Office
  • Air Corps INT
  • Medical Aid Post
  • Sgt Majors Office
  • Signals Bottom Workshop
  • Signals Top Workshop
  • Signals COMCEN
  • Signals Orderly Room & CO’s Office
  • Signals PC Maintenance Workshop
  • Signals Stores
  • Station Commanders Office

Main Tech Stores

Illness & untimely deaths in Main Technical stores can be explained by the fact that the building is sited on the old Camp Stables where hundreds if not thousands of litres of toxic chemicals such as Ardrox 666 were dumped into the ground. Complaints were made by civilian & military personnel about poor air quality  in MTS and studies were carried out but the reports have disappeared. There is also evidence that used chemical drums containing isocyanates were stored in MTS in an open state.

Photo Section

When photo section moved out of the Main Block to the old cookhouse in the early 1990s they brought their dangerous chemicals to this new locations. This new location was better equipped than the expellair in the main block. But faulty equipment and lack of chemical health & safety training meant illness & death continued.

Photographers who flew regularly exposure to refueling fumes, exhaust gasses from gas turbine engines and the immune sensitisation capabilities of polyurethane coated immersion suits.

Refuelers

Obviously refuelers were exposed on an ongoing basis to high amounts of refueling fumes and aircraft exhaust gasses but also to other dangerous additives like FSII.

Training Depot

On at least two occasions that we are aware of there was catastrophic damage caused to floors and walls by misuse of chemicals in ACTD.

On the first occasion in the late 1980s we are aware of a recruit using what we suspect to be a large quantity of MEK on twine backed traditional lino the last room on the left of the depot. The use of the chemical on this occasion melted the lino through to the twine backing.

On the second occasion in the mid 1990s at least 25 litres of trichloroethylene was used to clean the floor of some of the demonstration rooms that had been recently redecorated. The Trike was spread on the floor using mops and squeegees making the apprentices carrying out the job high. The next morning it was discovered that all the floor tiles had shriveled up and that all the paint on the walls up to about 1m had dissolved and flowed down the walls to the floor.

For some information on Illnesses caused by MEK click here.

*****

The physical layout of Baldonne means that the prevailing wind blows the exhaust gasses from idling aircraft over the whole camp.

There does not appear to have been any initiative whatsoever to reduce camp personnel exposure to exhaust gasses and in many cases aircraft exhaust into hangars due to the prevailing wind.

We have little information on chemical exposures at Gormanston except for tubbing and the use of JetA1 powered heaters inside hangars. We would welcome any information in this regards.

Dutch Neurologist Warns of ‘Parkinson’s Pandemic’ Linked to Toxic Chemicals

As the world frantically battles coronavirus, a leading Dutch neurologist warns of the next global pandemic — and this one, he says, is almost entirely of our own making.

Bastiaan Bloem, MD, a neurologist and professor at Radboud University Nijmegen Medical Center, says that over the next 20 years, the number of people with Parkinson’s disease (PD) will likely double — from the present 6.5 million to more than 13 million.

The main cause of this exponential jump: widespread exposure to herbicides, solvents, and other toxic chemicals used in agriculture and manufacturing.

“A pandemic, as everybody is now painfully aware, is a disease happening worldwide, to which no one is immune. PD fulfills all those criteria,” Bloem told Parkinson’s News Today in a phone interview from the Netherlands.

“Parkinson’s is now the fastest-growing neurological condition on the planet.”

Bloem, 53, points to the tight link between exposure to herbicides such as paraquat — a weed killer — and the risk of developing Parkinson’s.

“These chemicals were introduced worldwide after World War II, and many are still used today on our fields,” he said. “For this reason, farmers are at a markedly increased risk of developing Parkinson’s. If you feed a mouse paraquat — which is banned in China but not the U.S. — it will kill the dopamine-producing cells in the brain. These chemicals are tremendously toxic to the brain and have even been detected in milk, in supermarkets.”

Paraquat isn’t the only such chemical posing this risk. Trichloroethylene, a solvent used to clean metals and remove stains, has exactly the same effect on human brains. Yet it’s still widely used and is detectable in high concentrations in groundwater, he said.

“Parkinson’s is exploding in numbers, it’s a horribly debilitating disease, and it’s a costly disease that should matter to people and governments. We’re doing this to ourselves,” Bloem said. “But we can do something about it. We need to get rid of these toxic pesticides and move toward organic food. And we should take measures to protect people who work in these toxic environments.”

Dutch Neurologist Warns of ‘Parkinson’s Pandemic’ Linked to Toxic Chemicals

*****

Trichloroethylene was used in Baldonnel for decades with ERF in particular receiving it in 220 litre drums. From ERF it was handed out without any precautions or training to anyone who asked for it. It was handed out in milk cartons, plastic coke bottles etc.

Trichloroethylene was used by all hangars & workshops in an ad-hoc basis usually with Trichloroethylene begged from ERF although some units did order it themselves. Personnel in the Air Corps museum also used Trike to help degrease parts & aircraft being restored for the museum. 

Trichloroethylene was also used by both apprentices, tech & line personnel to carry out cleaning tasks in the Air Corps Training Depot while on training courses or during “war week”.

In at least 2 separate instances some floors in ACTD were completely destroyed by the use of Trichloroethylene being left overnight to clean them. In one incident Trichloroethylene dissolved through a traditional lino floor as far as the backing twine and in another incident few years later a tiled floor was destroyed after the tiles shriveled up & shrunk after Trichloroethylene  was left overnight to clean a floor.

Trichloroethylene was also used by teenage apprentices to clean black marks off floors in the Apprentice Hostel and the Apprentice School.

At no point was anyone ever given training in the use of Trichloroethylene nor issued with appropriate PPE whilst working with the chemical.

A number of Irish Air Corps personnel have been diagnosed with early onset Parkinson’s disease

DELAY – DENY – DIE

Making babies – Another human cost of the Irish Air Corps Toxic Chemical Health & Safety scandal

This article was originally published in June 2017 and is being republished as Lunchtime Live on Newstalk 106FM cover IVF & Fertility stories. 

Making babies the hard way.

There is something shameful and deviant about sitting in a small public toilet in a busy public hospital masturbating. Other people want to use the toilet, you are trying to be as quick and as quiet as possible but you have a job to do and you cant leave the cubicle until it is done.

Welcome to the glamorous world of infertility. I was married a number of years at this stage and my wife was starting to worry that pregnancy wasn’t happening for us. She had established contact with a maternity hospital over her worries. She was given a clean bill of health and now it was my turn and this started with a semen analysis to establish if I had a sufficient sperm count and also to establish the health & motility of these.

I presented at small hatch in in one of Dublin’s maternity hospitals where I was given a container, verified my name, address and DOB and was sent on my way to find a free toilet cubical where I could “produce” a sample.

After the job was done I returned the sample to the hatch where I was told that results would be available within the hour, not to me but to my wife’s gynaecologist. So the next day I rang his office for the results and was told that he couldn’t fit me in for an appointment for at least 3 weeks. This pissed me off greatly as I knew a semen analysis is an “eyeball” count and I wasn’t too keen to hang around for weeks awaiting the result.

I sought the consultant’s number and left a message for him to call me back to put me out of my misery. He called me back and confirmed what I had started to suspect…I had a serious fertility problem. A healthy sperm count was between 50 and 100 million sperm per m/l and mine was only 1 million. Considering that the average intercourse attempts before pregnancy in a healthy couple was 1 in 4 attempts my odds of creating a natural pregnancy were one in 400. Essentially it could take 33 years of monthly attempts for success not 4 months.

And there was worse news to come when we finally did sit and meet with the gynaecologist. Of those 1 million sperm that I did have over 90% were immotile or defective in some way so now my odds had lengthened to a 1 in 4000 chance of pregnancy. Now being fairly certain that we didn’t have over 300 years of monthly sex to create a family it became readily apparent we needed the intervention of fertility specialists. The gynaecologist told us our only option was ICSI a particularly expensive specialist form of IVF. Intracytoplasmic sperm injection is a procedure in which a single sperm is injected directly into an egg.

In that meeting with the gynaecologist I felt numb and totally drop kicked. I had reached the stage in my life where I wanted to become a father. The previous summer I had been on a rocky beach in the West of Ireland with my wife, her sister and two nieces. I remember walking along the beach with my 1 & 3 year old nieces, lifting over rocks to see the creepy crawly creatures under them, the subsequent delight of the kids and had thought “yep I could be a dad” .

As you can imagine my wife was utterly distraught at the news that we could not have children naturally. She is very good with children and had a much stronger instinct and desires for parenthood than me. The gynaecologist said that considering our ages (early thirties) and the severity of my infertility that we had no time to waste and he recommended Clane IVF clinic.

Starting IVF involves a lot of rigmarole. Further medicals, testing & analysis, and also regular tests for STDs such as hepatitis & HIV in order to protect their staff &  maintain a quality trail.

And of course during this build up our family and circle of friends are popping out sprogs like there is no tomorrow. When you find out you can’t have children naturally you start to notice every single pregnant woman you pass. Everyone is pregnant except you guys.

I do recall a dinner we went to in a friend’s house where there were 3 couples present. The host couple already had a child and over the course of the dinner the other couple declared “they had an announcement” they were expecting their first child. Obviously they were bursting with pride & happiness and we were very happy for them but immediately I could sense that my wife was distressed but “holding it together”.

After the meal was over and we said our goodbyes my wife broke down as soon as she got inside our car. It is unfortunately a reality for childless couples that other people’s good news can cause them pain. I suppose it invokes a panic that perhaps the IVF will never work and leads to a fear that we would never have “an announcement” of our own.

Eventually we received our prescription for the IVF medication which mainly injectable hormones for my wife. Although I was the one with the fertility problem all the treatment of egg production, egg harvesting and embryo transferral was naturally enough focused on my wife. She carried the can 100% for my infertility.

So off we skipped with our prescription like kids to a sweet shop, we could hardly contain our excitement. My wife required daily injections and I was the injector. Initially we were very giddy and one of our biggest problems was that one or other of us would get into a fit of giggles. It is not very easy to give an injection when one or other of you is shaking like a leaf from laughter. I became very skilled at giving the injections and on more than one occasion managed to give an injection that my wife didn’t even notice.

Part of the treatment involved regular inter-vaginal ultrasound monitoring to observe and monitor the growth of eggs. Normally a woman produces one fertile egg follicle per month alternating ovaries but during IVF the fertility drugs promote Controlled Ovarian Hyper-stimulation whereby a larger number of ripened egg follicles are produced. This is in order to harvest as many eggs as possible so that a number of embryos can be created. This increases your odds of success, IVF is very much numbers game.

I accompanied my wife to the first scan and everything was hunky dory so when some work commitments happened to coincide with the next scheduled scan my wife was happy to travel to the clinic on her own as we just saw the scan as routine and had no reason to fear anything was going amiss. So she headed down to Clane on her own and about an hour later I got a call from my wife who was sobbing uncontrollably at the other end. The nurse performing the scan had ultrasound had inserted the probe and then had gone white, she called the doctor urgently and he went white. It turned out my wife had started Hyper Ovulation Stimulation Syndrome and the cycle had to be stopped immediately.

So there and then our current chances of becoming parents evaporated. Many people will talk about the emotional roller-coaster that is IVF but we never paid much heed. We made a serious mistake and that was we never contemplated failure. We only contemplated success, failure wasn’t even on our mind, so when that failure did come we were totally unprepared. It was like the chair had been kicked out from underneath us.

As mentioned IVF essentially involves Controlled Ovarian Hyper-stimulation but Hyper Ovulation Stimulation Syndrome is a very dangerous condition where the woman reacts “too well” to the fertility drugs and produces too many ovarian follicles and is at risk of essentially an internal overdose of hormones leading to respiratory, cardiac or renal problems and can be fatal.

So getting over this HOSS involved stopping treatment and then careful monitoring to make sure the threat dissipated, we then needed my wife’s regular ovulation cycle to get back on track and as you can imagine this took a number of months. We found Clane IVF clinic to be very professional, very supportive and always felt they had our best interests to the fore and would not rush treatment cycles.

For many patients of IVF, the first cycle really is like the zeroing shots at range practice. It allows the IVF professionals get an idea to the responsiveness to IVF drugs of one woman’s body compared to another’s.

For our second cycle the IVF injection dose was adjusted and we made some significant adjustments to our expectations. This time we only contemplated failure and decided that success would be a bonus. This approach we believed would protect us somewhat from disappointment if the cycle failed again.

This cycle however went well and a date was set for February 2008 for the harvesting procedure. Again this involves an inter-vaginal ultrasound probe just this time with a retractable lance that is able to burst each follicle and extract the egg. At the time the IVF clinic was in a portacabins at Clane General Hospital and there was a small 3 bed-roomed ward next to the theatre which was connected via a hatch to the Embryology laboratory.

So my wife got gowned up and was sedated for the procedure as I waited on my own in the small ward. Eventually my wife was brought back into the ward in a wheelchair, bleeding and with tears running down her face and streaming down her neck. For me this was an extremely low point of my life. I felt extremely guilty because this was my fault, I was infertile not my wife. If I was functional she would not have needed to go through this.

So I’m sitting beside my wife who is upset and confused because of the sedation I’m trying to comfort her and then one of the IVF nurses called in to us to tell us the egg harvesting had been a success and that now it was “my turn”. I was handed a small sample container and had to go into a room I had nicknamed “the milking parlour” to have the most important wank of my life. If you pardon my porn reference this was the “money shot”, I had to produce and my aim had to be impeccable.

Once I provided the sample it was handed over immediately to the embryologist and he went and worked his scientific magic of ICSI. IVF is now a very well understood procedure but many people are a bit horrified when they realise the scientific & medical technology was adapted from the livestock industry.

So I believe that 18 eggs were harvested and treated with ICSI. This resulted in 15 successfully fertilised eggs. We opted for a service that matured the zygotes a bit longer in the lab. While this was more expensive it also improved the odds of success when transferred.

I think it was 2 weeks later that we went back for the eggs to be transferred. To improve the chances of success Clane transferred 2 zygotes in what is a relatively straightforward procedure and then it was a waiting game for 2 weeks until the first blood test.

Those 2 weeks are a time of huge anticipation. Do you cheat and try a home pregnancy test or do you wait until the official, higher accuracy, blood pregnancy test. So we waited until the official test and you have to then wait for a phone call from the lab to give you the good or bad news. Like I said we had dampened down expectations but it was till nerve racking.

When the news came it was positive, we were going to be parents. Naturally we were overjoyed and we kicked into “nesting mode” and what turned out to be an uneventful and normal pregnancy.

Our first child,  was born in October 2009 and when I first set eyes on him I became very emotional. Tears came out of nowhere as I sobbed uncontrollably looking at this helpless little bundle swaddled in a hospital blanket, blinking and yawning and wondering where he was.

We still had some frozen embryos and so a year or so later we decided to try for another cycle. This time we chose to transfer only a single embryo as a year or so into being parents neither of us fancied the thoughts of being parents of twins. But again, we made the mistake of not contemplating failure, again we thought everything would work like it did the previous time. So cycle 3 was a failure but as well as that all along the different phases of harvesting, fertilisation, transfer, freezing and thawing there was an attrition rate and so after cycle 3 we only had 2 fertilised zygotes left.

Again, after a failed cycle my wife needed a number of months for her menstrual cycle to get back to normal before we could go for the 4th cycle attempt. We took the decision to transfer our last 2 remaining embryos taking the chance on twins rather than the expense of a further cycle. Like in the case of our first pregnancy only one embryo took and in May 2012 our second son was born.

Both boys are now in school with one in Junior Infants and the other in First Class of our local school. Both are healthy fun loving kind kids with a love of the outdoors and both have a curious mind and 99% of the time they are a pure joy to raise. The thought always fascinates me as to how would their personalities be different if they had been transferred in the opposite order. Technically they are twins being conceived on the same day but just born over 2 years apart.

IVF was an expensive undertaking and we spent many tens of thousands of euro. I am conscious of many of my Irish Army Air Corps colleagues with fertility difficulties remain childless because either the IVF technology was not mature enough at the time to deal with their level of infertility or because they simply could not afford the cost of the procedure.

I have no doubt that my fertility trouble stemmed from my working environment in the Irish Air Corps at Casement Aerodrome, Baldonnel. The working conditions were horrendous,  we had no chemical training whatsoever, we were issued with no PPE whatsoever and the buildings that housed the chemicals I worked with were asbestos clad brick sheds built by the British in 1915-1918 and were unfit for purpose as they had utterly inadequate ventilation.

Chemicals we worked with in Baldonnel were exceptionally dangerous and were listed as Carcinogens, Mutagens and Teratogens and a number of chemicals in daily use were reproductive toxins and warned of harm to fertility as well as the capacity to cause heritable genetic harm.

My wife and I are definitely one of the luckier couples from Baldonnel, many couples have not been able to have children and will move into an old age that will be lonelier as a result. It is one thing if you don’t want a family but to want a family and be denied it because your employer didn’t give a damn about Health & Safety is galling.

Worse still I believe are the serving and former personnel who have managed to have children but whose children have suffered serious physical & mental disabilities due to their parents unprotected chemical exposure during their service in the Irish Army Air Corps. Many of these chemicals have the capacity not only to harm sperm, eggs and the developing child but also to harm the male &  female reproductive organs increasing the chance of disabled children long after leaving the service.

Infertility is common and on the increase but the levels of infertility or fertility difficulties experienced by male personnel in the most chemically contaminated workshops in Baldonnel appears anecdotally to be as high as 50%.

This is another health effect of the chemical Health & Safety failings that needs full investigation by competent medical & scientific bodies.

Whistle blower who raised concerns over alleged chemical exposures seeks Air Corps inquiry

A whistleblower who has raised concerns over alleged chemical exposures in the Air Corps says the force used five of the same chemicals at the centre of a cancer scandal involving tech giants Samsung.

The whistleblower has compiled a list of 70 deaths of former Air Corps staff that he believes should prompt an investigation into chemical exposures at the force’s headquarters in Casement Aerodrome.

South Korean company Samsung last week apologised for the sickness and deaths suffered by some of its workers after they were linked to chemical exposures in its facilities. Dozens of employees have experienced grave illnesses such as leukaemia and brain tumours.

Samsung and a group representing ailing workers agreed compensation terms after a highly publicised standoff that had been ongoing for more than a decade. The president of its device solutions division said the company failed to “sufficiently manage health threats” at its plants

SHARPS (Supporters for the Health And Rights of People in the Semiconductor industry) is a group campaigning on behalf of those who worked in Samsung facilities and subsequently suffered illnesses.

Its website has listed case studies and chemicals used by Samsung, including trichloroethylene, a known carcinogenic used by the Irish Air Corps until 2007.

This newspaper has previously revealed the details of an internal Air Corps memo that said it is possible staff may have ingested Triklone N, a vapour degreaser that contains trichloroethylene,  over a 27-year-period.

The memo said staff could have suffered other exposures because there was no record that protective measures were in place to mitigate the impact of the toxic solvent.

The summary of an internal Air Corps report, compiled in 2014, asks: “Can the Defence Forces be found not to have done everything reasonably practicable?”

Department of Defence coy on probe of bullying claims

An air corps whistleblower has been told that it is “difficult to envisage” how the Department of Defence would investigate complaints of bullying made in a protected disclosure about chemical exposure within the force.

The protected disclosure, seen by the Irish Examiner, contains allegations that the whistle-blower was doused in chemicals used to service aircraft as an initiation, and was frequently exposed to chemicals without protective equipment as he carried out his duties in the Engine Shop at Casement Aerodrome, Baldonnel.

He alleges that he became ill while still serving in the air corps, but was targeted by superiors for his frequent absences due to sickness.

His complaints match those of a number of other whistleblowers, and the State is currently facing at least seven separate legal actions from former air corps staff who claim they are chronically ill due to their exposure to chemicals at Casement Aerodrome.

A Government-commissioned report by former civil servant Christopher O’Toole into earlier whistleblower disclosures found there was no documentation available to demonstrate that the air corps met its health and safety obligations.

The latest whistleblower called on the Government to launch a fresh review into the complaints about conditions in Casement Aerodrome, and asked that his allegations of bullying be considered as part of this probe.

“My allegations need to be investigated in full as part of a wider investigation into the air corps chemical exposure scandal and the subsequent bullying and mistreatment of personnel injured by the same chemical exposure,” states the whistle blower.
