Two Plans to Reduce Soot

Federal regulators are looking at two plans for reducing the
amount of soot in the air. As the Great Lakes Radio Consortium’s Sarah
Hulett reports, public health advocates say tougher regulations would
prevent thousands of premature deaths from heart and lung disease.


One of the plans would cut the amount of pollution in a 24-hour period by more than half. A second plan would allow a little more soot each day, but it would cut the total amount allowed each year. EPA Administrator Stephen Johnson is expected to make a make a choice between the two plans by the end of the year.


EPA researchers looked at the links between air pollution and premature death in nine U.S. cities. Janice Nolen is the director of national policy for the American Lung Association.


“In those nine cities they were estimating that each year, about five thousand people died of particle pollution, where the standards are right now.”


Nolen says the standards EPA is considering would greatly reduce those deaths. The new standards would take effect in the fall of 2006.

Study: Air Pollution Affects Birth Weight

Cars, trucks and coal-fired power plants contribute to fine particle pollution, or soot. That type of pollution can be harmful for adults with heart or lung problems, and kids with asthma. A new study suggests that the pollution can also affect developing babies. The Great Lakes Radio Consortium’s Rebecca Williams has more:

Cars, trucks, and coal-fired power plants contribute to fine particle pollution, or soot. That type of pollution can be harmful for adults with heart or lung problems, and kids with asthma. A new study suggests that the pollution can also affect developing babies. The Great Lakes Radio Consortium’s Rebecca Williams has more:


This study was the first to look at fine particle pollution and developing babies in the U.S. Researchers looked at more than 18,000 babies that were carried to full term in California. They found that mothers living in areas of high exposure to fine particles had babies that weighed about an ounce less than mothers living in low exposure areas.


Tracey Woodruff is a senior scientist with the Environmental Protection Agency. She co-authored the study in the journal Pediatrics. Woodruff says an ounce is a small difference in birth weight, but it’s significant enough to merit more research on particulate matter – also known as “p.m.”


“This is one more piece of information about adverse health effects of p.m., which is feeding into the larger literature, which is leading EPA to embark on a number of different activities to try to reduce the levels.”


Woodruff says future research should look at whether fine particle pollution is related to premature births.
