Document Summary
Most outdoor pollutants in urban areas enter the atmosphere from burning fossil fuels in power plants and factories (stationary sources) and in vehicles (mobile sources) Emitted directly into the troposphere in a potentially harmful form. Primary pollutants interacting with one another to form new pollutants. Colourless irritating gas: mostly from coal burning o. Suspended particle matter (spm: variety of different aerosols o. From coal, diesel burning and road paving: health, ecological and physical damage. Ozone: highly reactive gas forms in the troposphere, made from chemical reactions between emitted compounds and nitrous oxide. Paint, manufacturing, batteries: accumulates in the brain and causes serious problems. Most scientists say yes b/c: high concentrations o o. Increasing faster than can be compensated by trees growing back. Contributes to global warming via the greenhouse effect. A mixture of air pollutants formed by the reaction of nitrogen oxides and volatile organic hydrocarbons under the influence of sunlight. Produces more than 100 primary and secondary pollutants.
