General Pollution

Air pollution is the world's largest single environmental health risk with more than four million deaths occurring from indoor pollution exposure. Sources of this pollution are numerous and include particulate matter, carbon monoxide, ozone, nitrogen and sulfur oxides, radon and volatile organic compounds. Combustion sources and emissions from everyday products, like toys and indoor furnishings, and activities, like cleaning and cooking, contribute complex mixtures of gases and particles to the air. Overall, the majority of people spend approximately 90% of their time indoors where the air is 2-10 times more polluted than the outdoor air. Indoor air quality is an important predictor of health and is associated with a wide range of health outcomes, ranging from asthma exacerbation to cancer. Our efforts are directed to helping mitigate sources of pollution and exposure through scientific research and communication.
