JunkScience.com recently obtained through the Freedom of Information Act documents describing human clinical experiments involving high exposures to particulate matter conducted by the University of Rochester with EPA funding.
As background, here is how the EPA described the risk of inhaling airborne fine particulate matter (PM2.5), i.e., soot or dust much smaller in diameter than the width of a human hair in its December 2012 Federal Register notice tightening the PM2.5 ambient air quality standards:
Note that EPA says that short-term exposure to PM2.5 in outdoor air can cause a fatal heart attack.
At the University of Rochester, human study subjects up to age 60 were exposed to much-more-than-normal outdoor air levels of PM2.5:
But despite exposing human study subjects to 20 TIMES the level of PM2.5 in outdoor air, the University of Rochester researchers told the institutional review board responsible for approving the experiment:
Note that the EPA’s alleged emergency room visits and deaths related to heart attack are, in reality, “small” and “theoretical” even in those with “severe coronary artery disease”!
EPA’s PM2.5 rules cost the American economy hundreds of billions of dollars. Oddly enough, they will serve as the primary justification for the agency’s upcoming ozone standards, anticipated to be the most expensive EPA regulations of all time — all built on demonstrable lies.
