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

Posted on 01/11/2015 1:51:08 PM PST by smokingfrog

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.

The problem is, this is more than enough for the EPA to ban diesel engines. The radical greens want us to go back to living in thatched huts and eating low hanging fruit. They assume, of course, that they themselves will be among the .001% who survive.

You mean they didn’t have them each put their mouths on the tailpipe?

“The problem is, this is more than enough for the EPA to ban diesel engines.”

Or oil fired boilers.

USEPA has been super aggressive in regulating diesels.

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.

I can remember our family car following a bus through one of the Allegheny tunnels when I was a 6 year old. I puked my guts out! Feel the same way today about diesel fumes! Really obnoxious!

They envision themselves living in PanEm. The rest of us, District 13.

Like 1984 every time someone writes a dystopian novel, they think it's a blueprint.

But I must add, tech has probably gotten a lot better since 1952!

Stay out of bathroom-sized rooms with diesel fumes being pumped in if you have asthma. Got it

I remember being in the motor pool on alerts when the entire M-60A3 tank battalion would fire up and wait around in case we got the order to head for the hills. Lots-o-deisel.

That’s not official - just his estimate.
But it has lots of torque!

Seems way low, especially rapped out at 3600 RPM.
