Air Pollution To understand pollution of air‚ some knowledge of the atmosphere is required. Atmosphere is a layer consisting of a few gases surrounding the planet earth and is vital for the survival of life on earth. The atmosphere protects earth from abrupt temperature fluctuations from the powerful ultra violet radiation coming from the sun. The atmosphere is made up of nitrogen 78%‚oxygen 21%‚argon 0.9%‚carbon dioxideo0.03% and small amount of trace gases ‚helium ‚neon‚ krypton‚ xenon‚ hydrogen

Air pollution – contaminants or substances in the air that interfere with human health or produce other harmful environmental effects. Read our “What is Air Pollution?” article for further information. Alternative energy – usually environmentally friendly‚ this is energy from uncommon sources such as wind power or solar energy‚ not fossil fuels. Alternative fuels – similar to above. Not petrol or diesel but different transportation fuels like natural gas‚ methanol‚ bio fuels and electricity. B

Air Pollution * Pollutants enter the air from various sources‚ but burning of fossil fuels contributes the most to air pollution. * Exhaust fumes from vehicles contains soot (tiny carbon particles)‚ lead (from cars using unleaded petrol)‚ carbon monoxide‚ oxides of nitrogen and hydrocarbons due to the incomplete combustion of fossil fuels. * Burning of fossil fuels in the combustion engines of vehicles and electrical power stations also releases large amount of carbon dioxide into the

Relationship between marginal cost and marginal product. Marginal cost is the additional cost attributed to an additional unit produced. Marginal product is the increase in the total product due to an additional resource allocation. The marginal cost and marginal return have an inverse relationship and can almost be represented as mirror images of each other. The peak of the marginal product corresponds with the lowest point of the marginal cost. Thus as marginal product increases

What are the different types of air pollution? How does each of these types of air pollution affect human health and the environment? What some ways to control air pollution? Industrial smog is the black-brown colored haze that is in the air that can be seen over some cities. It is mostly visible in the summer. Burning coal produces sulfur dioxide (SO2) that eventually ends up into our atmosphere. Photochemical Smog is air pollution containing ozone and other reactive chemical compounds formed
