Skip to comments.Diesel exhaust a danger after 2 hours, indicates UBC study

Just two hours of exposure to diesel exhaust is enough to cause significant damage to the human body, a new UBC study concludes.
The study, led by Dr. Chris Carlsten, looked at how pollution particles affect the way genes are expressed in the body.
Sixteen non-smoking adult volunteers with asthma were put in an enclosed booth about the size of a standard bathroom, and made to breathe diluted and aged exhaust fumes equal to the air quality along a Beijing highway, or a busy port in British Columbia.
Carlsten says the impact of the pollution "exceeded our expectations."
"Quite rapidly, it turns out, we're showing in hours, you observe changes in the blood that may have long-term implications," said Carlsten.
It's believed exposure to the particles affects the chemical "coating" that can attach to parts of a person's DNA.
"That carbon-hydrogen coating, called methylation, can silence or dampen a gene, preventing it from producing a protein sometimes to a persons benefit, sometimes not.

I worked in confined spaces in the military and believe it.
I wonder if they were volunteers or “volunteers”.
Just think of the health effects of being locked into a tiny room with a hippy
“...Sixteen people with asthma

Little kids being bussed all over the place for integration.
I had an open work space directly above a diesel repair facility.... for a few weeks...
it really got to me!
I have not seen any three eyed truck drivers.
I doubt the output from a Gas engine exactly has health giving properties.
Not new research. Back in the early 1940s, German scientists ran a similar experiment where they put folks in a bus, sealed it off from the driver, and drove around with the exhaust vented into the passenger compartment. While the results established that the exposure to diesel fumes was harmful to the subjects, it was determined that the process was not cost effective.
The Germans figured this out in the 40's.
Oh great. I’m reading this from an idling diesel surrounded by other idling diesels. And there’s nothing I can do about it.
In other news... “it was found that prolonged exposure to water has serious health effects”
as a kid going to visit my grandparent in NYC I absolutely loved the smell of the bus exhaust.
Anyway, maybe this has a lot to do with the new report that getting cancer is a matter of chance. I do not believe in chance but I know evolutionists do so it was probably diesel fuel that caused all those good mutations.
Diesel fumes tend to make me sneeze a lot. I guess I'd never make it as a truck driver.
