Nearly a third of the U.S.
population, or 96 million people, live in areas with unsafe levels of
fine-particle pollution, according to a report by the U.S. Public
Interest Research Group, an advocacy group.
PIRG analyzed levels of particle pollution in the U.S. in 2004 based
on a survey of state environmental agencies. Coal-fired electric power
plants are the largest source of fine particle pollution, which can
cause respiratory and cardiovascular problems.
"Children, senior citizens and even healthy adults suffer asthma
attacks and other health problems from soot pollution," said Emily
Figdor, a PIRG spokeswoman.
PIRGīs report, based on a survey of environmental agencies in all 50
states and the District of Columbia, concluded that fine-particle
pollution exceeded either the annual or the 24-hour health standards in
55 large, midsized, and small metropolitan areas in 21 states.
California, Pennsylvania, Utah, Georgia and Ohio had the worst
fine-particle pollution, according to PIRG, which has called on Congress
to strengthen legislation that would reduce small-particle pollution.
However, a group representing some of the nationīs electric power
plant operators dismissed PIRGīs findings, saying they are misleading.
"U.S. PIRG has again attempted to scare the public regarding particle
matter pollution," said Scott Segal, director of the Electric
Reliability Coordinating Council. In fact, Segal said, pollution levels
have been decreasing because of emission control steps undertaken by
electric power plant operators. Particle pollution levels have declined
even as overall energy consumption has increased 41 percent since 1999,
he said.
