Air Pollution 1 Air Pollution Air pollution is a gas (or a liquid or solid dispersed through ordinary air) released in a big enough quantity to harm the health of people or other animals, kill plants or stop them growing properly. It damage or disrupt some other aspect of the environment (such as making buildings crumble), or cause some other kind of nuisance (reduced visibility, perhaps, or an unpleasant odor). 2 Climate Processes and Air Pollution Air pollution is defined as any contaminant added to the air that is harmful to the health of living organisms. Due to the nature of air and wind, this pollution can be carried great distances. Industrial contaminants can be found in places that have virtually no population. Contaminants especially concentrate at the poles. 3 Air Pollution 4 Air Pollution Cairo-Black clouds are caused by hypertoxic emissions of annual burning of rice stubble in rural areas, and car exhaust fumes. Long-Range Transport 6 Outdoor Air Pollution Primary - Released directly from planet’s surface. Dust, smoke particles, Nitrogen, Carbon etc. Secondary - Formed when primary pollutants react or combine with one another, or basic elements. Primary Air Pollutants Parameters 1. Carbon Monoxide Produced when organic materials are incompletely burned. Single largest source is the automobile. Not a persistent pollutant. Binds to hemoglobin in blood and makes the hemoglobin less able to carry oxygen. Most dangerous in enclosed spaces. Cigarette smoking an important source. Primary Air Pollutants Parameters 2.0 Volatile Organic Compounds Hydrocarbons - Group of organic compounds consisting of carbon and hydrogen. – Evaporated from automobile fuel or remnants of fuel incompletely burned. – Catalytic converters used to burn exhaust gases more completely. Primary Air Pollutants Parameters 3.0 Particulates Minute pieces of solid materials dispersed into the atmosphere (
