Study Links Air Pollution to Blood Clots

A Harvard School of Public Health Study determined that exposure to particulate matter in air pollution may increase risk of dangerous blood clots in the legs.

Dr. Andrea Baccarelli, who led the study said, "Several studies in animal models and in humans have shown that particulate matter, inhaled into the lungs, causes inflammation in the lungs."

Los Angeles is one of the most heavily polluted cities in the United States and is impacted by transport-related air pollution. Exhaust from automobiles and trucks, ships and machinery include small particulates, as small as one-40th the width of a human hair, which can have dangerous health consequences.
