The World Health Organization concluded last year that diesel exhaust
is carcinogenic.
An estimated 6 percent of lung cancer deaths in the United States and
the United Kingdom – 11,000 deaths per year – may be due to diesel
exhaust, according to a new study.

Emission standards for diesel engines have become more stringent in
recent years, but their exhaust still plays a significant role in lung
cancer deaths among truckers, miners and railroad workers, the authors
wrote. In addition, diesel exhaust still poses a major cancer threat
for people living in dense cities or near highways, they said.

Truckers and miners exposed over their careers to diesel exhaust face
a risk of deadly lung cancer that is almost 70 times higher than the
risk considered acceptable under U.S. occupational standards. The
scientists calculated the lifetime risk for these workers at up to 689
extra lung cancer deaths per 10,000 workers exposed. In comparison,
one cancer death per 1,000 workers is used to set federal workplace
standards.

In addition, people in urban areas face a lifetime risk of lung cancer
that is 10 times higher than the acceptable risk used in U.S. health
standards, according to the study. An estimated 21 per 10,000 people
exposed to the amount of diesel exhaust commonly found near U.S.
highways would be at risk of dying of lung cancer over their lifetime.
That compares to the risk of one death per 100,000 people that is used
to set air-quality standards.

To come up with their calculations, the researchers from Emory
University and several other U.S. and European institutions used data
from three previous studies of workers – two of truckers and one of
non-metal miners – as well as national death statistics for the United
States and United Kingdom.

They estimated that 4.8 percent of lung cancer deaths in the United
States and the United Kingdom is due to occupational exposure to
diesel exhaust, while 1.3 percent is due to environmental exposures to
the exhaust. [Editor's Note, 11/27/2013: Corrected error in
description of percentages.]

"With millions of workers currently exposed to such levels, and
likely higher levels in the past, the impact on the current and future
lung cancer burden could be substantial," the authors wrote.

The researchers said their estimates "are far from precise and
depend on broad assumptions." But they said their findings are
"generally consistent" with past findings. Other factors,
such as smoking, were not taken into account. They used the assumption
that smoking does not modify effects of diesel exhaust.

The World Health Organization concluded last year, after reviewing
health data for workers, that diesel exhaust is carcinogenic.
Diesel emissions have declined substantially over the past few years
in the United States and Europe since new engine standards were
initiated. More than 50,000 high-polluting diesel engines were cleaned
up or removed from U.S. roads between 2008 and 2010, according to an
Environmental Protection Agency report. About 230,000 tons of soot and
smog-causing pollutants were eliminated, according to the report.

However, while buses and trucks have largely adopted cleaner
technology, it's taken longer for off-road engines, such as farm and
construction vehicles.

yea the WHO known for being idiots, using "Broad assumsions" make it up
out of thin air again. KB
