WASHINGTON, Feb. 7, 2012 /PRNewswire-USNewswire/ -- Despite reductions in US air pollution over the past several decades, resulting from the combined efforts of government, nonprofit and industrial sectors, concentrations of both fine particles and ozone remain a public health concern, particularly in urban areas. A new study by economists, scientists, and modelers at the U.S. Environmental Protection Agency (EPA) shows that levels of fine particulate matter (PM2.5) and ozone (O3) pose...

For the first time on Saturday, Beijing officials released data disclosing the amount of minute particles polluting the air in what Reuters has called "of the world's most heavily polluted capitals." According to the Xinhua news agency, the Beijing Environment Protection Monitoring Center revealed that a monitoring station in the city detected 0.003 micrograms of fine particular matter of 2.5 micrometers or less in diameter (PM2.5), which equates to an air-quality rating of "good." The...

Wood-burning stoves are a popular source of heating in many countries. However in recent years there has been much debate about the potential negative health effects associated with wood smoke. A Norwegian researcher has studied the influence of combustion conditions on the emissions and their health effects. Wood-burning is controversial in many countries, including the USA and Canada. Some groups wish to ban wood-burning whereas others are trying to convince opponents that clean-burning...

Image 1 - Smoke Particles Are Not All the 'SAME'

Where there's smoke, you need a functioning smoke detector that can tell the difference between, say, smoke particles and dust. Yet in the microgravity environment of the International Space Station, telling the difference between an actual fire and a false alarm may not be so simple. To understand how best to detect smoke in space, researchers from NASA's Glenn Research Center flew the Smoke Aerosol Measurement Experiment, or SAME, aboard the space station. This experiment was originally...

A study conducted by researchers at Boston University School of Medicine (BUSM) has found that diesel exhaust particulates (DEP) and house dust extract (HDE) causes pulmonary inflammation that aggravates asthma. The study led by principle investigator Jiyoun Kim, PhD, professor of pathology, was published in the December issue of The American Journal of Pathology and was selected by the editorial board as the only article for an in-depth discussion in the journal's commentary section....

After monitoring firefighters working at prescribed burns in the southeastern U.S., University of Georgia researchers found that lung function decreased with successive days of exposure to smoke and other particulate matter. "What we found suggested a decline in lung function across work seasons," said Olorunfemi Adetona, a postdoctoral research associate and lead author of the study published recently in the journal Inhalation Toxicology. Luke Naeher, senior author and associate...

Metabolic syndrome biomarkers predict subsequent decline in lung function after particulate exposure, according to new research involving rescue personnel exposed to World Trade Center (WTC) dust. In a nested case-control study of 327 non-smoking FDNY 9/11 rescue workers, metabolic syndrome biomarkers measured within six months of exposure to WTC dust predicted decline of forced expiratory volume in one second (FEV1) over the next six years. "Study participants with dyslipidemia,...

Nonsmokers who live in locations with high levels of air pollution are approximately 20% more likely to die as a result of lung cancer than those who live in clean-air areas, a team of researchers claim in a new study. In their research, Michelle C. Turner, Daniel Krewski, C. Arden Pope III, and Susan M. Gapstur of the University of Ottawa, Yue Chen of Brigham Young University (BYU), and Michael J. Thun of the American Cancer Society's Epidemiology Research Program followed more than 188,...

A new study claims that air pollution can leave women with a 30 percent higher risk of giving birth prematurely. The study focused on 100,000 births and found that "toxic" chemicals emitted by urban traffic damages the health of unborn babies as well as their mothers. “Air pollution is known to be associated with low birth weight and premature birth," Dr Beate Ritz from the University of California said in a statement. “Our results show that traffic-related polycyclic...

HARRISBURG, Pa., July 1, 2011 /PRNewswire-USNewswire/ -- The PA Department of Environmental Protection and its regional air quality partnerships have forecast air quality action days for this weekend in four of Pennsylvania's forecasting regions. On air quality action days, young children, the elderly and those with respiratory problems, such as asthma, emphysema and bronchitis, are especially vulnerable to the effects of air pollution and should limit outdoor activities. The air...
