The Environmental Protection Agency has been conducting dangerous experiments on humans over the past few years in order to justify more onerous clean air regulations.

The agency conducted tests on people with health issues and the elderly, exposing them to high levels of potentially lethal pollutants, without disclosing the risks of cancer and death, according to a newly released government report.

These experiments exposed people, including those with asthma and heart problems, to dangerously high levels of toxic pollutants, including diesel fumes, reads a EPA inspector general report obtained by The Daily Caller News Foundation. The EPA also exposed people with health issues to levels of pollutants up to 50 times greater than the agency says is safe for humans.
