Direct causes of air pollution related deaths include aggravated asthma, bronchitis, emphysema, lung and heart diseases, and respiratory allergies. The worst short term civilian pollution crisis in India was the 1984 Bhopal Disaster. Leaked industrial vapors from the Union Carbide factory, belonging to Union Carbide, inc.,. A., killed more than 2,000 people outright and injured anywhere from 150,000 to 600,000 others, some 6,000 of whom would later die from their injuries. The United Kingdom suffered its worst air pollution event when the december 4 Great Smog of 1952 formed over London. In six days more than 4,000 died, and 8,000 more died within the following months Water pollution Water pollution is the contamination of water bodies (e. Lakes, rivers, oceans, groundwater).

Peroxyacetyl nitrate (PAN) similarly formed from NOx and vocs. Minor air pollutants aloud include: A large number of minor hazardous air pollutants. Some of these are regulated in usa under the Clean Air Act and in Europe under the air Framework directive. A variety of persistent organic pollutants, which can attach to particulate matter. Persistent organic pollutants (POPs) are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes. Because of this, they have been observed to persist in the environment, to be capable of long-range transport, bioaccumulate in human and animal tissue, biomagnify in food chains, and to have potential significant impacts on human health and the environment. Health effects of Air Pollution: The world health Organization states that. 4 million people die each year from causes directly attributable to air pollution, with. 5 million of these deaths attributable to indoor air pollution. Worldwide more deaths per year are linked to air pollution than to automobile accidents.
Smog is a kind of air pollution; the word smog is a portmanteau of smoke and fog. Classic smog results from large amounts of coal burning in an area caused by a mixture of smoke and sulfur dioxide. Modern smog does not usually come from coal but from vehicular and industrial emissions that are acted on in the atmosphere by sunlight to form secondary pollutants that also combine with the primary emissions to form photochemical smog. Ground level ozone (O3) formed from NOx and vocs. Ozone (O3) is a key constituent of the troposphere (it is also an important constituent of certain regions of the stratosphere commonly known as the ozone layer). Photochemical and chemical reactions involving it drive many of the chemical processes that occur in the atmosphere by day and by night. At abnormally high concentrations brought about by human activities (largely the combustion of fossil fuel it is a pollutant, and a constituent of smog.
This reddish-brown toxic gas has a characteristic sharp, biting odor. NO2 is one of the most prominent air owl pollutants. Carbon monoxide is a colourless, odourless, non-irritating but very poisonous gas. It is a product by incomplete combustion of fuel such as natural fuller gas, coal or wood. Vehicular exhaust is a major source of carbon monoxide. Carbon dioxide (CO2) a greenhouse gas emitted from combustion but is also a gas vital to living organisms. It is a natural gas in the atmosphere. Odors — such as from garbage, sewage, and industrial processes Radioactive pollutants produced by nuclear explosions, war explosives, and natural processes such as the radioactive decay of radon. Secondary pollutants include: Particulate matter formed from gaseous primary pollutants and compounds in photochemical smog.
Major primary pollutants produced by human activity include: Sulfur oxides (SOx) especially sulfur dioxide, a chemical compound with the formula so2. SO2 is produced by volcanoes and in various industrial processes. Since coal and petroleum often contain sulfur compounds, their combustion generates sulfur dioxide. Further oxidation of SO2, usually in the presence of a catalyst such as NO2, forms H2SO4, and thus acid rain. 2 This is one of the causes for concern over the environmental impact of the use of these fuels as power sources. Nitrogen oxides (NOx) especially nitrogen dioxide are emitted from high temperature combustion. Can be seen as the brown haze dome above or plume downwind of cities. Nitrogen dioxide is the chemical compound with the formula no2. It is one of the several nitrogen oxides.

This prompted some of the resume first major modern environmental legislation, The Clean Air Act of 1956. Air pollution Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the earths ecosystems. Pollutants An air pollutant is known as a substance in the air that can cause harm to humans and the environment. Pollutants can be in the form of solid particles, liquid droplets, or gases.
In addition, they may be natural or man-made. Pollutants can be classified as either primary or secondary. Usually, primary pollutants are substances directly emitted from a process, such as ash from a volcanic eruption, the carbon monoxide gas from a motor vehicle exhaust or sulfur dioxide released from factories. Secondary pollutants are not emitted directly. Rather, they form in the air when primary pollutants react or interact. An important example of a secondary resume pollutant is ground level ozone — one of the many secondary pollutants that make up photochemical smog.

The term non -point source encompasses a large range of sources like when rain and snow moves through the ground and picks up major pollutants and mover towards a major body essay of water, the runoff of fertilizers from farms animals and crop lands, air pollutants. Land pollution: The contamination of and with different kinds of wastes is called land pollution. The major causes of land pollution are construction, domestic waste, industrial waste and agriculture. The rising construction of building takes away the trees that takes away the homes of the animals living there. As there are more and more people inhabiting on our planet, the demand for food increases and the forests are cut down to make farm lands. In addition, herbicides, pesticides, artificial fertilizers and animal manure are washed into the soil and pollute. Tons of domestic waste is dumped everyday from homes offices etc. They can be recycled or burnt in incinerators.
by the burning of plastic foam items, leaking refrigerator equipment and spray cans. Water pollution: Contamination of available natural water by industrial wastes and other waste products can be defined as water pollution. Factors causing water pollution can be categorized into two different groups; point sources and Non- point sources. Point sources are easy to identify and control. Some point sources of water pollution include waste products from factories, waste from sewage, waste from power plants, waste from underground coal mines and waste from oil wells. They are called point sources because these are the direct sources of water pollution and be reduced and monitored. Non- point sources are ambiguously defined and are much harder to control.
The effect of pollution can be experienced in different ways. The most common ways of pollution are: Air pollution, water pollution, land pollution. Air pollution: This tern is not something new, it has been existing since paper he time of industrial revolution where in big chimneys are pointed out in the air which releases harmful gases into the atmosphere. This phenomenon has been increasing since then as the industries have been developing simultaneously. Today, air pollutants have shown a great effect on plantations, health and life, decreasing the enjoyment of living, rising medical costs, causes global warming and also causes the destruction of the ozone layer. One of the major causes of air pollution is the release of carbon di oxide into the atmosphere. This happens because of deforestation and fossil fuel burning. Sulfur dioxide is another main air polluter and is released into the atmosphere by the burning of sulfur containing compounds of fossil fuels.

Print, reference this, published: 10th June, 2016 10th June, 2016. Pollution 'pollution the most commonly used word in our everyday life relating to the destruction of the natural air we breathe, the water we drink and the land we live. No doubt the world is rapidly developing in every area possible which makes our lives much easier to live but on the other hand forgetting that we ourselves are first destroying the natural resources. Many environmental researches have proved that it is because of the rapid growth in technology and other areas of growth that leads to a massive increase the growth of pollution. The unexpected pollution caused is mainly due to the human activities such as globalization, industrialization, and expanding increase in technology. This change is experienced not in a short term but in a long run, when it slowly started affecting people. Pollution can be formally defined as the undesirable and unintended contamination of the environment by human activities such as manufacturing, waste disposal, burning fossil fuels etc.
