BURNING TOPIC

• Pollution is the introduction of contaminants into a natural

environment that causes instability, disorder, harm or discomfort to the ecosystem i.e. physical systems or living organisms.

Pollution can take the form of chemical substances or energy,

such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally

occurring contaminants.

TYPES OF POLLUTION:-

There are major following types of

pollution including:

Air Pollution

Water Pollution

Soil Pollution

Noise Pollution

Air Pollution

Air pollution is perhaps the most common and the most dangerous type of pollution. It involves the direct release of

chemicals into the environment.

Causes-

Basically, the air pollution is caused by the burning of fuel that directly releases hazardous chemicals into the air.

For example, the burning of coal releases sulphur dioxide, a poisonous gas which is responsible for acid rain.

Soil Pollution

Soil pollution involves the contamination of soil by the release of harmful substances into the soil. Unlike air pollution, which has a direct affect on human lives

Causes Of Soil Pollution:

Soil pollution is mainly caused by the release of industrial waste. This waste is directly incorporated into the soil by large industries and factories. Soil pollution is also caused by human acts as mining and deforestation etc.

Water Pollution

o The 75% of the earth’s surface is covered with water and more that half of the total population of earth’s species resides in water.

Cause Of Water Pollution

o Just like air and soil pollution, water pollution is caused by the direct incorporation of hazardous pollutants.

o The sources of these pollutants are yet again the large industries and factories that dispose off their waste in lakes and ponds.

Noise Pollution

o Noise is defined as an unpleasant sound that has an adverse affect on the human ear.

Cause Of Noise Pollution

o Noise pollution is caused by the moving vehicles, man made machines and loud music. Other than that noise can be caused by anything, but these three sources are the main reasons for the noise pollution around us.

POLLUTION CONTROL

Practices

Recycling

Reusing

Reducing

Preventing

Pollution control devices

• Scrubbers– Baffle spray scrubber– Cyclonic spray scrubber– Ejector venturi scrubber

• Industrial wastewater treatment

– API oil-water separators– Biofilters– Dissolved air flotation– Ultrafication systems
