Document Summary

Most groups focus on water: visible improvement, health concerns fairly rapid. 7-10 mill people die every year due to air pollution causes/risks: chemicals in the air have more of a long-term effect, both indoor and outdoor air pollution are dangerous. Contributes to method of exposure to air pollution. Cities, buildings, diesel busses, coal burning, cooking with fuels, smoking, etc. Access to healthcare systems, teachers, police, etc. Outdoor environment: cars/vehicle traffic: boats, planes, rvs, etc. Industrial byproducts: common/criteria pollutants: co, no2, lead, ozone, particulate matter (pm10, pm2. 5), sulfur dioxide. Identified by epa under clean air act (naaqs) standards.

Cardiovascular disease, esp. blood brain barrier: who air quality guideline: Lead (air pollution): was in gasoline, and in floorboards. 1980-2013: gdp increase, vehicle miles increase, population slight increase, energy consumption minor increase, co2 emission minor increase, six common pollutants major decrease!
