ES102 Lecture Notes - Lecture 6: Asbestosis, Poverty Reduction, Volatile Organic Compound
Document Summary
International accord was created (unfccc) to attempt controlling ghg emissions. Major problem - china"s air quality crisis. Two types - natural and anthropogenic sources. Origins - formed from incomplete combustion of carbon-based fuel. Impairs ability of bloodstream to deliver oxygen where needed. At higher levels of exposure, cause birth defects and death. Description - no= short lives, no2 = reddish-brown. Origins - formed when burning of fossil fuels. No2 is a key ingredient in photochemical smog, acid rain. Smog elevates medical visits for respiratory illness, asthma. Mostly in areas where fossil fuels are burned - picture to the right -----> Origins - formed when coal is burned. Increases medical visits for respiratory illness, asthma. Description - bad smelling, short lived gas. Description - various small molecules and droplets light enough to be temporarily suspended in air. Occurs when airborne nox, ozone and volatile organic compounds react under uv radiation. Photochemical smog is shown on the ontario air quality index.
