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