plese write an essay on" pollution "?

Question

i want something related to pollution its harms and how can we prevent it

Answer 1

Sources and causes



Air pollution


The Lachine Canal, in Montreal, is polluted
Arguably the principal source of air pollutants worldwide is motor vehicle emissions, although many other sources have been found to contribute to the ever growing problem. While the U.S. has adopted stringent emissions controls, the EU has not been as assertive in this field; nevertheless, the U.S. is still the leading contributor to mobile source air emissions merely due to the very high number of vehicle miles traveled per capita.
Principal stationary pollution sources include chemical plants, coal-fired power plants, oil refineries, nuclear waste disposal activity, incinerators, large animal farms, PVC factories, metals production factories, plastics factories, and other heavy industry.
Some of the more common soil contaminants are chlorinated hydrocarbons (CFH), heavy metals (such as chromium, cadmium--found in rechargeable batteries, and lead--found in lead paint, aviation fuel and still in some countries, gasoline), MTBE, zinc, arsenic and benzene. Ordinary municipal landfills are the source of many chemical substances entering the soil environment (and often groundwater), emanating from the wide variety of refuse accepted, especially substances illegally discarded there, or from pre-1970 landfill may have been subject to little control in the U.S. or EU.
Pollution can also be the consequence of a natural disaster. For example hurricanes often involve water contamination from sewage, and petrochemical spills from ruptured boats or automobiles. Larger scale and environmental damage is not uncommon when coastal oil rigs or refineries are involved. Some sources of pollution, such as nuclear power plants or oil tankers, can produce widespread and potentially hazardous releases when accidents occur.
In the case of noise pollution the dominant source class is the motor vehicle, producing about ninety percent of all unwanted noise worldwide.
[edit]
Effects on human health

Pollutants can cause diseases, including cancer, lupus, immune diseases, allergies, and asthma. Higher levels of background radiation have led to an increased incidence of cancer and mortality associated with it worldwide. Some illnesses are named for the places where specific pollutants were first formally implicated. One example is Minamata disease, which is caused by mercury compounds.
Bad air quality can kill. Ozone pollution can cause sore throats, inflammation, chest pain and congestion. Oil spills can cause skin irritations and rashes. Noise pollution induces hearing loss, high blood pressure, stress and sleep disturbance.
Contamination caused by pollution can have damaging effects in the brain and central nervous system. Studies have shown that brain of animals actually shrink from prolonged exposure to contaminants in the environment 1.

Answer 2

The object which causes pollution is called pollutant. Basically pollution is of three types- Air pollution, Water pollution and Noise pollution.

Air pollution:-

Air pollution is caused by the factories which is near by the residential areas, autobiles, factories,etc... It is also caused by toxic gases. The toxic gases are Hydrogen Sulphide, Nitric oxide, Nitrous Oxide, Sulphur oxide, Sulphur-di-oxide, Carbon-mono oxide, Carbon-di-oxide. Air pollution also leads to asthma, bronchities, and other respiratory diseases.

Water pollution:-

Water pollution is caused by the waste water let out by the factories, waste water let into the ocean,seas and other water bodies.This also leads to typhoid, malaria.

Noise pollution:-

Noise pollution is also caused by the factories due to the machineries.Noise pollution leads to diseases to ear problems.

Major there is heat pollution, thermal pollution and other pollutions.

Answer 3

Pollution itself is too much dangerous so not to think about the essay on this.

Answer 5

hahaha... yeah right. Use this place for "research" if you must, but don't expect people to write whole essays... The longer answers are just copied and pasted from somewhere... Don't recommend turning any of those in...

Answer 6

Pollution is the release of chemical, physical, biological or radioactive contaminants to the environment. Principal forms of pollution include:

air pollution, the release of chemicals and particulates into the atmosphere. Common examples include carbon monoxide, sulfur dioxide, chlorofluorocarbons (CFCs), and nitrogen oxides produced by industry and motor vehicles. Ozone and smog are created as nitrogen oxides and hydrocarbons react to sunlight.
water pollution via surface runoff and leaching to groundwater.
radioactive contamination, added in the wake of 20th-century discoveries in atomic physics. (See alpha emitters and actinides in the environment.)
noise pollution, which encompasses roadway noise, aircraft noise, industrial noise as well as high-intensity sonar.
light pollution, includes light trespass, over-illumination and astronomical interference.
visual pollution, which can refer to the presence of overhead power lines, motorway billboards, scarred landforms (as from strip mining), open storage of junk or municipal solid waste.

What is air pollution?

The moment you step out of the house and are on the road you can actually see the air getting polluted; a cloud of smoke from the exhaust of a bus, car, or a scooter; smoke billowing from a factory chimney, flyash generated by thermal power plants, and speeding cars causing dust to rise from the roads. Natural phenomena such as the eruption of a volcano and even someone smoking a cigarette can also cause air pollution.
