Types of pollution:

The natural resources which are freely available a gift of nature are polluted and they can be broadly divided into following types like

Air pollution: This is a contamination of natural air with dangerous gases. This is a major contributor to environmental pollution. Presence of lot of green trees and plants is one of the option to minimize this pollution.air pollution

Many gases like carbon monoxide, carbon dioxide, sulfur dioxide, methane and other harmful gases are emitted from automobiles (powered by petroleum), industries and sometimes by natural calamities like volcanoes.

Another type is particulate air pollution, seems many of us are quite unaware about it. But if one stays near any industry, then it can be noticed. There is always some sort of particulate dust from the chimneys of the factory. This is harmful especially to the respiratory system are it is directly exposed.

This air pollution can be minimized by filtration of effluents, decrease in use of petroleum related automobiles and also sufficient growth of trees.

Water pollution: After air, water is resource which is highly contaminated.

This makes the water harmful to drink and also endanger lives of sea and marine animals.

Land pollution: Land pollution is one which occurs due there is excess dumping of toxic waste. This can be a chemical or other waste material. land-pollution

Polluting the land by harmful chemicals can lead to entry of pollutants into food chain. This is commonly caused by excess use of fertilizers in agriculture, irresponsible disposable of industrial wastes etc. Even defecating in the open spaces also causes pollution. This leads to health issues like malnutrition as pollutants pass through plants to humans and animals.

Sound pollution: Also called as noise pollution is a disturbance of silent environment with harsh loud noises. This is mostly due to automobile sounds, the audio systems used for fun or public speeches, temples, mosques, churches etc. This pollution has severe impact especially on the old people, small children. Even sound from industrial sirens, vehicle movements also contribute to this noise pollution.

Dust pollution: This is a pollution where in the contamination is due to dust particles in air. This can be from soil, roads, farming, and even due to mining etc. From farms this dust pollution occurs due to pollen grains as a part of pollination. While on the roads it is due to unclean road over run by vehicles. This air contamination by dust creates trouble for proper breathing leading to infections, congestion of breath etc.

Radiation pollution: This is the pollution due to abnormal radiation in the environment. This occurs due to use of radioactive elements from atomic energy stations.  From cell and mobile towers, by use of wireless Internet access modems etc. This is one of the serious types of pollution and also neglected one with the interest of business. Even it is said that birds like sparrows and insects like honey bees seem to be getting extinct from human areas due to these radiations.

Thermal pollution: This pollution arises due to release of excess heat from thermal power plants, industries involved in metals molding etc. The heat is released into the surrounding air rising the temperature of the locality drastically. This can be especially troublesome during summers for the people staying in the same city or locality.

Light pollution: This type of pollution might seem quite strange but it is one of the common pollution. Have you ever tried to see the sky for stars or for lunar eclipse when there is a cricket or football match going on in a nearby stadium? It is quite impossible. Even heavy light of opposite vehicles on the same road can lead to distractions for drivers. Light pollution effects especially at night as it disturbs the sleep of humans, birds and other animals. This might some times affect the natural body rhythm or circadian clock. It is believed that light pollution is one of the causes of obesity, insomnia and other health issues.

Plastic pollution: This is not a type but it deserves to be said one. The plastic and polythene due to their ability to withstand decomposition for years together add up to pollution. Plastic pollution can contribute to air, water and soil pollution. Even animals which graze this plastic die due to problems in the intestine.
