Cause of Air Pollution: The various causes of air pollution are: Natural air pollutants include a pollen, spores, b marsh gas, c volcanic gases and a synthesis of harmful chemicals by electric storms and solar flares. Concentration of industries in one area is another major cause of air pollution.
Effect of Air Pollutants: Air pollutants are broadly classified into particulate and gaseous. The particulate substances include solid and liquid particles. The gaseous include substances that are in the gaseous state at normal temperature and pressure. The air pollutants have adverse effect on human beings, animals, vegetation, buildings.
Aesthetic sense is also influenced by air pollutants. The different air pollutants and their effects are as follows: It is of two types—settleable and suspended. The settleable dusts have a particle longer than 10 am. The smaller particles are able to remain suspended for long periods in the air.
The important effects of particulate matter are. Smog harms plant life through glazing and necrosis besides reduced availability of light.
In human beings and animals it produces respiratory troubles. It is formed by incomplete combustion of carbon fuels in various industries, motor vehicles, hearths, kitchens, etc. Carbon monoxide combines with haemoglobin of blood and impairs its oxygen carrying capacity.
At higher concentration, carbon monoxide proves lethal. They occur mainly in the form of sulphur dioxide. It is produced in large quantity during smelting of metallic ores and burning of petroleum and coal in industries, thermal plants, home and motor vehicles. It causes chlorosis and necrosis of vegetation.
Sulphur dioxide, above 1 ppm, affects human beings. It causes irritation to eyes and injury to respiratory tract. It results in discolouration and deterioration of buildings, sculptures, painted surfaces, fabrics, paper, leather, etc.
They are produced naturally through biological and non-biological activities from nitrates, nitrites, electric storms, high energy radiations and solar flares. Human activity forms nitrogen oxides in combustion process of industries, automobiles, incinerators and nitrogen fertilizers.
Nitrogen oxides act on unsaturated hydrocarbons to form peroxy-acyl nitrates or PAN. It gives rise to photochemical smog. They cause eye irritation, respiratory troubles, blood congestion and dilation of arteries.
Due to excessive combustion activity, the content of C02 has been steadily rising. As carbon dioxide accumulates in the atmosphere it absorbs more and more of the reflected infrared radiation.
This could cause an increase in temperature referred to as the green house effect. Melting polar ice caps and glaciers could cause sea levels to rise, flooding most of the major population centres and fertile lands.Albrecht Dürer: The Genius with a Great Soul.
