A government watchdog group has obtained documents detailing how the EPA exposed children as young as 10 to deadly air pollutants without disclosing the full risks of the substances.
Government watchdogs say these EPA-backed studies could violate California state and federal law, because children were exposed to diesel exhaust in experiments with no health benefits to the subjects.
Between 2003 and 2010, the EPA backed experiments done at the University of Southern California and the University of California, Los Angeles which exposed children aged 10 to 15 to diesel exhaust — an air pollutant which the EPA and the California Air Resources Board says has no safe exposure limit.
CARB found in 1998 that based “on available scientific information” there is no “level of diesel exhaust exposure below which no carcinogenic effects are anticipated has not been identified.” This statement was made by CARB six years before the EPA-backed studies took place. The EPA lists diesel exhaust as a “likely” carcinogen.
