WATER POLLUTION.

Water Pollution. The Contamination of water with undesirable substances which make it unfit for usage is termed water Pollution..

SOURCES OF WATER POLLUTION. Most of Water Pollution is man made It may also occur naturally by addition of soil particles through erosion animal wastes and leaching of minerals from rocks.

The sources of water pollution can be classified as  Municipal Waste Water  Industrial Waste  Inorganic Pollutants  Organic Pollutants  Agricultural Wastes  Marine Pollution  Thermal pollution.

MUNICIPAL WASTE WATER.

INDUSTRIAL WASTE.

INORGANIC POLLUTANTS.  They include fine particles of different metals, chlorides, sulphates, oxides of iron, cadmium, acids and alkalies..

ORGANIC POLLUTANTS.  They Include oils, fats, phenols, organic acids grease and several other organic compounds.

AGRICULTURAL WASTES.  Chemical fertilizers and pesticides have become essential for present day high yielding crops..

MARINE POLLUTION.  Ocean are the final sink of all natural and manmade pollutants. Rivers discharge their pollutants into the sea. The sewage and garbage of costal cities are also dumped into the sea. The other sources include, discharge of oils, grease, detergents, and radioactive wastes from ships ..

THERMAL POLLUTION.  Thermal Pollution of water is caused by the rise in temperature of water. The main source of thermal pollution are the thermal and nuclear power plants. The power generating plants use water as coolants and release hot water into the original source. Sudden rise in temperature kills fish and other aquatic animals..

AIR POLLUTION.

CAUSES OF AIR POLLUTION. Carbon dioxide-this happens because of Deforestation and fossil fuel burning. Sulfur dioxide –Due to the burning of sulfur containing compounds of fossil fuels. Sulfur oxides- very dangerous to humans at a high concentration. Sulfur in the atmosphere is responsible for acid rain..

INDUSTRIAL WASTE. Plastics factories, chemical plants, oil refineries, nuclear waste disposal activity, large animal farms, coal-fired power plants, metals production factories and other heavy industry all contribute to land pollution..

NOISE POLLUTION.

SOURCES OF NOISE POLLUTION. Transportation systems are the main source of noise pollution in urban areas. Construction of buildings, highways, and streets cause a lot of noise, due to the usage of air compressors, bulldozers, loaders, dump trucks, and pavement breakers. Industrial noise also adds to the already unfavorable state of noise pollution. Loud speakers, plumbing, boilers, generators, air conditioners, fans, and vacuum cleaners add to the existing noise pollution..
