CHICAGO, Feb. 14, 2011 /PRNewswire/ -- New studies by national experts in air quality monitoring and public health find that the impacts of two Chicago power plants on local air quality are a fraction of what has been claimed by those seeking to close them. In fact, the new studies conclude that emissions from the Crawford and Fisk plants owned by Midwest Generation account for less than one-half of one percent of particulate matter pollution in Cook County air. The studies released...

With millions of people warding off winter's chill with blazing fireplaces and wood-burning stoves, scientists are raising red flags about the potential health effects of the smoke released from burning wood. Their study, published in the American Chemical Society's (ACS') journal, Chemical Research in Toxicology, found that the invisible particles inhaled into the lungs from wood smoke may have several adverse health effects. It is among 39 peer-reviewed scientific journals published by ACS,...

(Ivanhoe Newswire) -- The air we breathe can negatively affect our hearts. However, using inexpensive, high-efficiency particle air (HEPA) filters reduces cardiovascular disease risk resulting from polluted air, according to a new study. The researchers studied healthy adults living in a small community in British Columbia where wood-burning stoves are the main sources of pollution. The researchers found that HEPA filters reduced the amount of airborne particulate matter, resulting in...

Using inexpensive air filters may help reduce cardiovascular disease risk that results from exposure to air pollution, according to researchers from Canada, who studied healthy adultsliving in a small community in British Columbia where wood burning stoves are the main sources of pollution. The researchers found that high efficiency particle air (HEPA)filters reduced the amount of airborne particulate matter, resulting in improved blood vessel health and reductions in blood markers that are...

By digitally photographing the tiny, hair-like blood vessels in the back of our eyes, researchers can now look directly at how small blood vessels like those that bring blood to the heart respond to air pollution. New digital photos of the retina revealed that otherwise healthy people exposed to high levels of air pollution had narrower retinal arterioles, an indication of a higher risk of heart disease. Previous studies linked pollution to heart disease. The new study, published this week in...

PM or particulate matter is a type of contaminant in the atmosphere, considered very harmful for health, ecosystems, climate change, conservation of materials and visibility. Chemist Ms Ainhoa Inza studied the presence of this particulate matter in the Autonomous Community of the Basque Country (CAV-EAE); concretely, the type known as PM10, made up of particles of less than ten micras in diameter. Amongst other things, the researcher compared the concentration of this kind of atmospheric...

In many developing countries, the absence of surface-based air pollution sensors makes it difficult, and in some cases impossible, to get even a rough estimate of the abundance of a subcategory of airborne particles that epidemiologists suspect contributes to millions of premature deaths each year. The problematic particles, called fine particulate matter (PM2.5), are 2.5 micrometers or less in diameter, about a tenth the fraction of human hair. These small particles can get past the body's...
