Diesel Engine Fumes Linked to Autism: Study

Could diesel fumes potentially be hazardous to unborn babies?

According to a recent study conducted by the Harvard School of Public Health, women exposed to diesel fumes during late pregnancy could double the risk of having a child with autism. Researchers found that the risk rises in areas with high levels of traffic pollution and women are most vulnerable during the last trimester of pregnancy. The study looked at the impact of exposure to PM 2.5s, a small pollution particle produced by diesel engines.

By collecting data on 116,000 women, researchers at the Harvard School of Public Health noted where those women lived during their pregnancies and compared it with data from the Environmental Protection Agency and other sources on levels of fine particulate matter air pollution. As a result, they identified 245 children who were diagnosed with autism and a control group of 1,522 children without autism. Researchers concluded that exposure to PM2.5 was significantly associated with autism during pregnancy though exposure before or after was not associated.

“Our data add additional important support to the hypothesis that maternal exposure to air pollution contributes to the risk of autism spectrum disorders,” said Marc Weisskopf, associate professor of environmental and occupational epidemiology and senior author of the study. “The evidence base for a role for maternal exposure to air pollution increasing the risk of autism spectrum disorders is becoming quite strong.”

After being stuck behind a truck spewing diesel and breathing it in for 10 minutes I certainly feel like I've had 20 IQ points (that I can't spare) lobbed off. Can't say if the link to autism is right or wrong, but my gut tells me that breathing in anything other than clean air must have some long term impacts.

It's almost always small box trucks and landscaping trucks with the exhaust at ground level (vs. big rigs with the pipes exhausting into the sky, though I know we end up breathing that also). Not that I'm a die hard tree hugger, but I really wish the EPA or someone would clean those types of vehicles up!

I wish they would ban gas powered leaf blowers and charcoal grills within city limits as well.

Probably the same people who think vaccines cause autism.
It was a good guess, IMO. Those people are helping get the most toxic ingredients out of vaccines (mercury, formaldehyde etc) and that's a very good thing.
Giving up to 24 vaccinations to children less than 1 yr old is insane

Much more information in this story. Many media sites are leaving out a lot of info.

Two important quotes from the study.
In addition, it's important to note that while this study found an association between air pollution exposure in pregnancy and the risk of autism, the study doesn't prove that smog exposure caused autism.
For example, he noted, it could be argued that exposure to air pollution is just a marker of lower income and less prenatal care, which could be the "real" risk factor.

Correlation does not imply causation.

Once again, folks are trying to blame external forces on something that is, by most impartial accounts, genetic.

The increase in the diagnosis of autism is mainly related to medical science's propensity to put a label on everything, and of course, it gives an excuse to medicate.

Just like the fraudulent vaccine study that was debunked a few years ago, I'm sure the agenda behind this particular study will also become known, or at the very least, the flaws in methodology will eventually be exposed.

:lmao:

Something in our environment is causing the reproductive process in humans to go a bit haywire. Sure, Diesels might have some effect there, but humans have been introducing all kinds of chemicals into our homes that were never there before. Could be some combination of things, Diesels or no Diesels.

my immediate thoughts are did they CHOOSE locations that ONLY have diesel exhaust and NO industry or incinerators /power stations ETC or is it more of a case PM2.5=autism + PM2.5= diesel exhaust
I also wonder if we time traveled back 100 years to when western cities where way more polluted and tested using todays tests what would the autism numbers be like as I believe a LOT of the cases are because of more sensitive screening and a lower criteria + western countries propensity to excessive testing

You do realize that many vaccines have bloated numbers, such as the whooping cough vaccine that turned out did squat, just as the flu shot.
If you believe vaccines are fully researched for their effectiveness and safety and that because the government says they are safe that's good enough than I have a bridge to sell you in Nevada

This is the push back against diesel.
Years ago, Europe chose diesel as a quick efficient way to lower the CO2 out put of cars but
in that haste, the ECE totally ignored or at least played down the severity of other pollutants
like NOX and particulate emissions. Pertol was taxed to the max to encourage the take up of
thosee more efficient diesels...

And now, Europe is changing the social agenda again, those same experts who convinced
everyone to switch to diesel are now publicly denouncing diesel, people who drive down the
street in a diesel car are being likened to rampant mass murderers ....good god save us all.

Do you know what I think,
I think European governments are broke and now that everyone with an lick of sense has
switched to diesel, it's time for the socialists to go to work on people's bank accounts
by taxing diesel and anyone who dares to use it. It has little to do with those nasty
emissions real or imagined... it's all about stripping more money form motorists.

Not really or in a full sense.

More about the other agenda's that do not want diesel around.

Can't compete with it even with all the rigging currently present - and all that sort of thing.

Hell, they cannot even make it against a conventional gasser - too many special interest groups on all sides really.....

Meanwhile..... anyone familiar with all the literature - including the two biggies about gassers that have disappeared from free or easy cheap public view ...... knows that without a doubt as far as automotive EM goes , the far greater concern is with specific regard to USA gassers. In particular DI equipped. - with higher compression.


The three and now soon to be four way cats are mini chemical reactors ..... and what they are splicing together is beyond - far beyond ..... not looking good.

The also soon arriving gasoline particulate filters will be just slightly better than window dressing .......



Also that aircraft and airports have far more impact of a far more negative nature than previously thought.

As does all kinds of Military activity........

As does airborne pollution from Asia, and shipping - especially with regard to and for the imports coming ashore.

Besides the massive duck involved with typical CI / 'gassers' and all the usual preframing, out right error and deliberate as well as unintended omission, currently available road going LD diesel is often blamed for every other conceivable source especially other middle distillate - including but not limited to older uncontrolled or barely controlled big and heavy commercial diesel equipment, heating oil, bunker oil etc - and even coal EM on occasion.


As to the rest, you can safely bet your ass that a bunch of stuff involving Big this and Big that - are why things are changing up so quickly and so badly.

The Vaccine Industry are today's equivalent to Big Tobacco from days of yore - not any of that has been handled sensibly either.

New and Improved as far as all the spin goes so really -

Any serious student comes up quickly upon that and all that goes with it.

The far more interesting thing ( 'imo' ) is to chase down ..... shall we say.......... is the common money behind it all.

And then, the actual people and processes behind all that.

Good work - hard work is being done ......


Meanwhile Fukushima is single handily changing the Pacific ( and elsewhere ) along the lines of an extinction event - which given how it has been handled it certainly is , and the Deep Water Horizon Fiasco ( still very much ongoing ) and all that goes with it are finishing off nicely all that is left on the otherside..... while fracking is taking care of what Monsanto et al hasn't destroyed in terms of ( US ) land based water supply.

*****

As far as transportation goes, the only possible way out - in the long run is without a doubt - non carbon fuels.

There will be........from necessity .......... imperfect steps along the way.

And some things with carbon based fuels that will end up 'almost there'.


'Gasoline' ( SI full or part time ) somewhat paradoxically needs the most work ( by far ) and outright replacement; and yet, in many ways that really matter...... has the greatest potential as a useful intermediate step.

Especially if one goes back further into the refinery chain and closer to the basestock.

Interesting perspective from forum members on a subject that I've got about 19 years of history with.

The diesel fuel thing sounds like nonsense to me yet the research I have found most valid is that 1 in 50 kids are born with an immature detoxification system that in the 1960 s, 1970 s and 1980s would have matured by the age of 3.

That's why the autism rates in the United States in those years mentioned including the 1980s was one in ten thousand....in 1990 the United States changed the vaccination protocol from 4 and 5 years old to 36 vaccines starting the first day of birth (hep b) between the first day of life and three years old.

For those who actually have an autistic child....I can assure you Wakefield was not a quack.....

For those who don't have an autistic child and chose to ignore my research...I wish you the best as you and your loved ones have children and grandchildren....

Only a one in 50 chance you'll ever remember this thread...instead of one in 10,000...(prior to 1990 vaccination protocol shift)

Simple solution would be to go back to vaccinating our children after the age of three...(like we did in the 1950 s, 1960 s, 1970 s and 1980s)

Seriously? Wakefield's study has been disproven time and again and his methods scrutinized heavily. He was a quack who (through his own communications) falsified his results as he expected to be able to profit heavily off the fallout that would result.

What he apparently didn't realize (and this just proves his stupidity) is that part of the basic tenets of science is the concept of repeatability. If nobody else can confirm your results then questions are going to be raised.

Autism just means that you are a genius in some categories, ignorant of others, but logical and analytic in everything. Politicians would be more productive and favored if they had Autism.

Did anyone notice that the source in the original article is the Daily Mail?

The Daily Mail is not even a reliable source when it comes to celebrity stories, and it's definitely not a reliable source when it comes to Science. Whenever you hear about a scientific discovery in the Daily Mail, no matter whether it's about autism, food or cancer, you should ignore the article and read the original paper instead. You're not going to get accurate scientific information from a tabloid newspaper.

The paper can be found here:

http://ehp.niehs.nih.gov/wp-content/uploads/advpub/2014/12/ehp.1408133.acco.pdf

Note that it only mentions the word 'diesel' once, when referring to a different study.

@America123
There is definitely politics driving this, be it direct as in legislation against diesel unless they meet expensive emission criteria or indirect via government support for research into toxicity of diesel emissions.

Everywhere you read, the government is supporting either fuel efficient gasoline or electrification, be that hybrids or EVs. I still believe that diesel has a major role in reducing fuel usage in light trucks and heavier Utilities as exampled by Ram and Jeep. So IMO, the government should be supporting endeavors in this area, the development of cleaner diesels with low NOX and particulate filters.

I think this serves the national interest regardless of fuel prices, too much money is still flowing out of the country, if we could reduce that outflow by 20%, imagine what that would do to the American economy, people may actually be able to spend more on domestic commerce and improve business activity as a whole.

Yeah you're right John. Milk is loaded with antibiotics. All the audits and inspections I have to do at milk plants, I'm not actually working, I'm just sitting in the cafeteria eating steak dinners while we pump your milk full of nasty hormones. :lmao:

But of course, I know nothing. It's not like I went to school for four years to learn this stuff or have six years working in the dairy industry or anything. :rolleyes:

And people wonder why the agricultural sector basically closed itself off to the public for so long. Even when we try to be open and educate people, they refuse to listen.

In any case, this thread has served its purpose.
