Pollution originating in Asia is being lifted into the stratosphere during monsoon season, where it then circles around the globe for several years, according to a new National Center for Atmospheric Research (NCAR) study released on Thursday. According to a press release put out on March 25 by the National Science Foundation (NSF), one of the sponsors of the study, the research team used satellite observations and computer modeling to demonstrate how summer circulation patterns force the air...

As you stroll down restaurant row and catch the wonderful aroma of food "” steaks, burgers, and grilled veggies "” keep this in mind: You may be in an air pollution zone. Scientists in Minnesota are reporting that commercial cooking is a surprisingly large source of a range of air pollutants that could pose risks to human health and the environment. They discussed the topic yesterday at the 239th National Meeting of the American Chemical Society. Deborah Gross, Ph.D., pointed out...

Everyone knows that carbon dioxide, the main greenhouse gas driving climate change, is a global problem. Now a Stanford study has shown it is also a local problem, hurting city dwellers' health much more than rural residents', because of the carbon dioxide "domes" that develop over urban areas. That finding, said researcher Mark Z. Jacobson, exposes a serious oversight in current cap-and-trade proposals for reducing emissions of heat-trapping gases, which make no distinction based on a...

Poor air quality apparently affects the running times of women in marathons, according to a study by Virginia Tech civil and environmental engineer Linsey Marr. Marr's findings come from a comprehensive study that evaluated marathon race results, weather data, and air pollutant concentrations in seven marathons over a period of eight to 28 years. The top three male and female finishing times were compared with the course record and contrasted with air pollutant levels, taking high...

Even the snow on Aconcagua Mountain in the Andes is polluted with PCBs. An international team of researchers detected low concentrations of these toxic, carcinogenic chlorine compounds in samples taken from America's highest mountain. The snow samples taken at an altitude of 6200 meters are among the highest traces found anywhere in the world of these substances, which have been banned since 2001. In particular, the samples contained more persistent compounds like hexachlorobiphenyl (PCB 138)...

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,...

Soot, ozone and methane need attention to deal with near term impacts on climate When world leaders meet in Copenhagen in December to hash out a treaty limiting carbon dioxide emissions, they should begin planning a future summit to address other pollutants "“ from soot to ozone "“ that don't remain in the atmosphere as long as carbon dioxide, but nevertheless are major contributors to global warming. That is the view of University of California, Berkeley, researcher Stacy C....

Those pristine-looking Alpine glaciers now melting as global warming sets in may explain the mysterious increase in persistent organic pollutants in sediment from certain lakes since the 1990s, despite decreased use of those compounds in pesticides, electric equipment, paints and other products. That's the conclusion of a new study, scheduled for the Nov. 1 issue of ACS' Environmental Science & Technology, a semi-monthly journal. In the study, Christian Bogdal and colleagues focused on...

Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...
