EPA study links diesel exposure to cancer

| Monday, September 09, 2002

After a decade of study, an Environmental Protection Agency report says inhaling diesel exhaust from large trucks and other sources over time can cause cancer in humans, AP reported.

While acknowledging uncertainties about the long-term effects of diesel exhaust exposure, the report says studies of both animal tests and occupational exposure suggest strong evidence of a cancer risk to humans.

Meanwhile, the 651-page report didn't attempt to estimate the probability of an individual getting cancer, given certain exposure to diesel exhaust.

The report's findings are based on emission levels in the mid-1990s, but the report said the results are valid because the slow turnover of truck engines has kept many of these vehicles on the road.
