A new study investigated the association between short-term exposure to ambient fine particulate matter and the risk of stroke and found that even low pollutant levels may increase that risk. Researchers from the University of Michigan studied the effects of air pollution in a southeast Texas community where there is a large petroleum and petrochemical industry presence. They identified ischemic strokes and TIAs from the BASIC Project, a population-based stroke surveillance project. (source: sciencedaily.com)
