It's no secret that the emissions leaving a car tailpipe or factory smokestack affect climate and air quality. Even trees release chemicals that influence the atmosphere. But until now, scientists have struggled to know where these organic molecules go and what happens to them once they leave their source, leading to models for predicting climate and air quality that are incomplete or less than accurate. A major collaborative effort of more than 60 scientists led by Jose-Luis Jimenez, an...

Scientists are reporting evidence that air pollution "” a well-recognized problem at major airports "” may pose an important but largely overlooked health concern for people living near smaller regional airports. Those airports are becoming an increasingly important component of global air transport systems. The study, one of only a handful to examine airborne pollutants near regional airports, suggests that officials should pay closer attention to these overlooked emissions,...

Infants who are exposed to higher levels of air pollution are at increased risk for bronchiolitis, according to a new study. The study appears in the November 15 issue of the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine. "There has been very little study of the consequences of early life exposure to air pollution," said Catherine Karr, M.D. PhD, assistant professor of pediatrics at the University of Washington and the paper's lead author. "This study...

Tree leaves may be powerful tools for monitoring air quality and planning biking routes and walking paths, suggests a new study by scientists at Western Washington University in Bellingham. The research will be presented at this month's Annual Meeting of the Geological Society of America in Portland, Oregon. Leaves along bus routes were up to 10 times more magnetic than leaves on quieter streets, the study found. That magnetism comes from tiny particles of pollution"”such as iron oxides...

A new mobile air research laboratory will help a team of researchers led by a Michigan State University professor better understand the damaging health effects of air pollution and why certain airborne particles - emitted from plants and vehicles - induce disease and illness. Jack Harkema, a University Distinguished Professor of pathobiology and diagnostic investigation in the College of Veterinary Medicine, will deploy the new 53-foot, 36,000-pound center - dubbed "AirCARE 2" - throughout...

Plumes of harmful air pollutants can be transported across oceans and continents -- from Asia to the United States and from the United States to Europe -- and have a negative impact on air quality far from their original sources, says a new report by the National Research Council.  Although degraded air quality is nearly always dominated by local emissions, the influence of non-domestic pollution sources may grow as emissions from developing countries increase and become relatively more...

Beijing is starting to see smog pollute the skies again, a year after staging a mostly pollution-free Olympics. Beijing took action to prevent damaging athlete's health by moving or cleaning up polluting factories, curbing traffic, and ordering a halt to all construction work. Even the state-of-the-art facilities the city built, like "Bird's Nest" Olympic stadium and "Water Cube" aquatic center, were created with the latest in energy-efficiency design. "All of the steps Beijing took to stage...
