What is air pollution?

Extracts from this document...


What is air pollution? Air pollution occurs when wastes dirty the air. People procuse most of the wastes that cause air pollution. Such wastes can be in the form of gases or particles of solid or liquid substance. These substances result chiefly from burning fuel to power motor vehicles. Industrial processes and the burning of garbage also contribute to air pollution. natural pollutants include dust, soil particles and naturally occurring gases. The rapid growth of population and industry and the increased use of automobiles and airplanes, have made air pollution a serious problem. the air we breathe has become so filled with pollutants that it can cause health problems. Polluted air also harms plants, animals, building materials and fabrics. In addition, it causes damage by altearing the earth's atmosphere. ...read more.


Metal smelting plants give off large amounts of sulphur oxides and particles containing lead and other metals. Plants that produce plastic foam are a major source of chlorofluorocarbons(CFC's),compounds of chlorine,fluorine and carbon. * Burning of solid wastes often creates a very visible form of air pollution-thick,black smoke. The burning of garbage, leaves and other refuse is banned in most countries. * Other sources of pollution include chemical sprays and organic chemicals used to start fires on charcoal grills. Forest fires also contribute to air pollution. In developing countries, the burning of forests and grasslands to clear areas for farming is a major source of air pollution. * Natural sources also contribute to air pollution. Microbes in the guts of cattle and in rice paddies break down plant materials and release an odourless gas called methane, a type of hydrocarbon. Effects of air pollution * Health. ...read more.


Carbon dioxide allows sunlight to reach the earth and warm its surface, but it prevents some surface heat from escaping out of the atmosphere. This greenhouse effect may produce significant climatic changes, which could destroy many kinds of plants and animals. Chlorofluoro carbons break down the layer of ozone in the earth's upper atmosphere. This layer protects plants and animals from harmful ultraviolet rays. * Other effects. Most materials deteriorate faster when exposed to the pollutants present in the air. concrete and stone are dissolved by air pollutants. Metals corrode faster than usual. plastics,rubber and fabrics are also damaged by air pollutants. Air pollution is closely realted to other forms of pollution. Sulphur dioxide and nitrogen oxides can react with water dropplets in the air to produce acid rain. Acid rain pollutes lakes and streams and in high concentrations, can harm soil fertility. ...read more.
