Particulate matter (PM) is estimated to cause over 3.7 million deaths/year worldwide. The U.S. Environmental Protection Agency (EPA) estimated that benefits of the Clean Air Act were over 30 times higher than costs, with a large portion of those benefits from averted mortalities due to decreased PM levels. Still over 74 million people in the U.S. live in areas exceeding health-based PM regulations. While there is strong and consistent evidence that PM affects health, many questions remain, such as which types of particles and sources of particles are most harmful; which populations are most susceptible or vulnerable; and how these health impacts will be affected by climate change. This seminar will present recent scientific evidence on how particles impact human health from epidemiological studies using national datasets on weather, air pollution, and health. Implications for decision makers and remaining challenges will be discussed.
