Diesel exhaust a danger after 2 hours, indicates UBC study
CBC News ^ | 1-8-15 | unattributed

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 person’s benefit, sometimes not.

I worked in NORAD and there is the entry tunnel is about a third of a mile walk. Diesel trucks going by constantly. They would run the vehicles inside the cave.

I’m just glad they didn’t do this to any Gitmo prisoners. Sounds like torture to me.

But fear not, now that the Mexican trucks are cleared to come in under NAFTA, there will be plenty of non-EPA compliant diesels to carry the freight.

It will be interesting to see if they end up being able to come in to California in non CARB compliant trucks unlike Americans.

I’m no fan of diesel, but I wonder if they’ll do a study on the harm done by ethanol? And not just to engines and the price of food.
