write any five sources of air pollution and their effect on living organism
Answers
Answer:
1. burning of treees
2. industries waste
3. chemical release in atmosphere
4. increase of carbandi oxide
5. release of gasses from vehicals
Answer:
1. Carbon monoxide (CO)
Carbon Monoxide is a highly toxic and dangerous pollutant, infamous for its lack of identifying color and smell. At one point, this gas was extremely prevalent in homes for use in domestic heating before it was found to be unsuitable, and it has since been replaced by much safer solutions such natural gas and electricity. However, this gas is far from extinct in human use.
Sources :-
Most commonly, Carbon Monoxide is produced by combustion engines running without modern catalytic converters. Other common sources of Carbon Monoxide are old gas and fuel appliances, incinerators, and even cigarettes.
Effects :-
Carbon Monoxide can have a profound effect on the environment as it is extremely poisonous and can contribute to very dangerous ground-level air and ozone conditions.
2. lead (PB)
Lead has long been known to be a dangerous substance. Once commonplace in nearly all gas and aviation fuels, there has since been a tremendous effort to reduce the amount of lead found in these substances. Since the introduction of lead-free gasoline, the volume of lead in the atmosphere has dropped enormously.
Sources :-
While efforts have been made to remove lead from fuel, it continues to be present in some aircraft fuel. Similarly, the outpouring of lead from metal processing plants and the release of lead from waste processes such as incineration and battery acid production means that there is still enough lead in the air to recognize it as dangerous pollution.
Effects :-
Lead can not only poison humans, but it also has a profound effect on natural ecosystems.Contaminating air, soil, and water, lead can cause damage to flora and fauna alike.
3. Ozone (O3)
Ozone is not inherently bad. After all, the ozone layer is one of the major protections mankind has against harmful solar radiation. However, ground-level Ozone has become a major problem in recent years.
Sources :-
Ground-level Ozone is formed by chemical reactions between multiple different oxides found in the air, which – when exposed to sunlight – can form new compounds and leave Ozone as a by-product. The majority of the emissions which make up Ozone come from the usual suspects, such as car exhausts, factory processing, electric utilities and power plants, and even some chemical solvents.
Effects :-
Ozone is a dangerous substance for most living organisms, and as such, an increase in ground-level Ozone has a notable effect on human health as well as the overall health of multiple ecosystems on land and in the seas.
4. Nitrogen Dioxide (NO2)
Nitrogen Dioxide is one of the oxides which can react to produce Ozone, but that is far from its only negative effect. Nitrogen Dioxide is one of the gases that one most commonly thinks of when considering air pollution: thick, brown, and choking, it is one of the more visibly harmful pollutants.
Sources :-
Nitrogen Dioxide, like many other pollutants, is most often released into the atmosphere by the burning of fossil fuels in car engines, airplane engines, factories, and power plants.
Effects :-
Effects: In addition to being a choking and obstructive gas in the air, Nitrogen Dioxide also has the propensity to react with other agents to form nitric acid and organic nitrates, contributing to the formation of acid rain.
Needless to say, Nitrogen Oxide has a huge effect on humans, increasing the likelihood of respiratory problems, cancers, and other lung problems. Acid rains produced by Nitrogen Dioxide are extremely harmful to plants and animals across the world and can lead to further problems in water systems.
5. Sulfur dioxide (SO2)
Sulfur Dioxide is a substance most closely associated with the steam age and locomotives, as the biggest culprit in its production is coal combustion. However, these days are not so far gone as you may have thought.
Sources :-
To this day, locomotives, ships, planes, and other equipment still produce huge volumes of Sulfur Dioxide. Industrial processes, particularly ore extraction and purification, are also producers of the gas.
Effects :-
Sulfur Dioxide, like Nitrogen Dioxide, is a compound that often mixes with other pollutants in the air to form harmful acids, but it is also harmful on its own. Common effects of Sulfur Dioxide poisoning are respiratory problems, eye problems, and even heart and circulatory problems. Importantly, Sulfuric Acid, created by the mixing of sulfur with water, is a potent acid that is not only destructive to human property but also to trees, soils, and water systems.
