Certain areas of the United States were spared the effects of climate change thanks to the presence of tiny particles in the atmosphere, suggests new research from climate scientists at the Harvard School of Engineering and Applied Sciences (SEAS). Lead author Eric Leibensperger, a graduate student in applied physics at SEAS at the time of the study, and principal investigator Daniel Jacob, a professor of atmospheric chemistry and environmental engineering at SEAS and a professor of earth...

Worldwide, smoke from landscape fires contributed to an average of 339,000 deaths per year between 1997 and 2006, according to new research published in Environmental Health Perspectives and released today during the Annual Meeting of the American Association for the Advancement of Science (AAAS). Sub-Saharan Africa and Southeast Asia were the hardest hit by fire-smoke deaths, with an estimated annual average of 157,000 and 110,000 deaths, respectively, attributable to landscape fire smoke...

Short-term exposure (for up to 7 days) to all major air pollutants, with the exception of ozone, is significantly associated with an increased risk of heart attack, according to a review and meta-analysis of previous studies appearing in the February 15 issue of JAMA. The potentially harmful effect of episodes of high air pollution on health has been suspected for more than 50 years. "In industrialized countries, cardiovascular disease is the leading cause of mortality and is associated...

Moderate Air Pollution Linked To Stroke, Cognitive Decline

Chronic exposure to air pollution, even at levels typically considered safe by federal regulations, increases the risk of stroke by 34 percent and may accelerate cognitive decline in older adults, according to two separate studies published this week in the Archives of Internal Medicine. In one study, researchers studied more than 1,700 stroke patients in the Boston area over a 10-year period, and found exposure to ambient fine particulate matter (PM), generally from vehicle traffic, was...
