From Detroit News’ Henry Payne:
At the University of Michigan, the Environmental Protection Agency (EPA) has been funding experiments on human beings to determine the effect of particulate pollution on their health. The tests are similar to others around the country that use mobile units to pump in filtered exhaust to labs exposing paid subjects to so-called PM2.5 particulates.
Trouble is, the same EPA that funds the studies claims that any exposure to PM2.5 particulates can be deadly…
In an interview, Brook says that the tests he has conducted were board-reviewed and exposed human subjects to unharmful, low levels of particulate matter less than what “tyou would receive from 1 or 2 puffs on a cigarette.” Indeed, control groups can be crucial to scientific knowledge.
But Brook’s argument that there are levels of risk to PM2.5 exposure contradicts EPA claims that there is no safe level of exposure.
Using test results from its university-funded research, EPA is now setting particulate levels so low — from the current 15 micrograms per cubic meter to 12 mcg — that critics say they have no effect on human health even as they costs jobs and billions in industry compliance.
The EPA has justified its new Cross-State Air Pollution Rule and the Mercury and Air Toxics Standards on the basis of risk assessment that PM2.5 can kill within hours of exposure. Yet, its disclaimer to human subjects says merely that “you may experience some minor degree of airway irritation, cough or shortness of breath or wheezing.”
Brook says that — while he has received EPA approval to conduct more testing — he is not going to conduct further experiments, though he says it has nothing to do with Milloy’s complaint. “I’m not going to do (these tests) because I don’t believe in exposing people,” says Brook. “I’ve shown PM2.5 is bad for you”…
