The word air pollution is surrounded by pangs of concern and clouds of worry. The health of humans, well being of other animals and the natural balance in the ecosystem, everything its and bits of life is threatened by air pollution. It initiates acid rain, creates smog, causes cancer , triggers allergies ,. It occurs when the harmful substances such as foreign gases , odour , dust , or fumes are present in the air at levels that can harm the comfort and health of animals and humans or even destroy plant life. Cars, trucks, jet airplanes and other combustion engine vehicles cause. Factories, office buildings, homes and power-generating stations burn fossil fuels,.
Petroleum refineries release hydrocarbons and various. Oil drills, submarines, and other vessels on and in the ocean can cause excessive noise that has resulted in the injury or death of marine animals, especially whales. All these industrial products at some point in their lifetime become obsolete,. Human dumping : Due to human dumping of waste and other harmful substances in to river water. Land water flow : Contamination during rains due to the flow of.
Anthropogenic (man-made) soil pollution originates in several types of processes, some deliberate and some accidental. Human-caused soil pollution can work in conjunction with natural processes to increase the toxic contamination levels in the soil. Almost all of the common air pollutants can be produced by industrial.
Transportation Emissions. Common forms of transportation like cars,. Agriculture Side-Effects. Farmers use machinery driven by fossil fuels to plow fields.
Some of the main causes of pollution include industrial emissions, poor disposal of wastes, mining, deforestation, use of fossil fuels and agricultural activities. Pollution can affect the air, the land and water bodies throughout the world. In big cities we witness hazy skies creating problems for the inhabitants and causing numerous diseases. Effluent from a treatment plant can introduce nutrients and harmful microbes into waterways.
Nutrients can cause a rampant growth of algae in water. Nonpoint-source pollution is the opposite of point-source pollution , with pollutants released in a wide area. In the Amazon rain forest in Brazil, an area the size of a football field is clear-cut by.
The world population increase and increased demand for a food supply is causing forests. Effects of Air Pollution. High levels of air pollution can cause an increased risk of heart attack, wheezing, coughing, and breathing problems, and irritation of the eyes, nose, and throat. Industrial activities often release. Water source based ground water pollution surface water pollution ), Surface Water Pollution (thermal water pollution , marine pollution , oil spills, etc.) Further there are other forms of water pollution chemical pollution , oxygen depletion of water, suspended water pollution , etc).
Sources ( Causes ) of noise pollution Sound of traffic with the roaring engines of trucks, buses, motorcycles and constant humming. Living in areas near the railways stations or airports. Air pollution causes irritation in the throat, nose, lungs and eyes. Working with loud tools such. It causes breathing problems and aggravates existing health conditions such as emphysema and asthma.
Contaminated air reduces the body’s defenses and decreases the body’s capacity to fight other infections in the respiratory system. Here are the few major causes of water pollution : Sewage And Waste Water: Sewage, garbage and liquid waste of households, agricultural lands and factories are discharged into lakes and rivers. These wastes contain harmful chemicals and toxins which make the water poisonous for aquatic animals and plants.
What is Air Pollution – Air pollution is nothing but, increase of toxic and harmful material in the air, resulting in contamination of air. These material may be in form of soli liquid or gaseous substances and released in air due to various activities by human beings causing an adverse effect to natural life.
