 ¢ That pollution
 ¢ pollution is the pollution with man-made waste. This includes, principally, ground, water and air.
Pollution is the introduction of  ¢ environmental pollution, which causes instability, disorder, harm or discomfort dlâthe ecosystem i.e. physical systems or living organisms
 ¢ types of pollution
 ¢ air pollution
 ¢ water pollution
 ¢ soil contamination
 ¢ radioactive contamination
 ¢ noise pollution
 ¢ light pollution (includes a light offence for lighting and astronomical interference.
 ¢ visual pollution
 ¢ thermal pollution
Land Pollution
Land pollution is the pollution with man-made waste on land.
Americans generated five pounds of solid waste every day, besides Creating a ton of solid waste a year.
A year on an average day in the United States, people throw away 200 thousand tons of edible food.
Main man contribution to the pollution of landfill. About half of our trash is in landfills.
Only 2% of our waste is recycled.
air pollution
THES is GMT gases, known as the "big six" air pollutants "
Carbon dioxide
Carbon monoxide
Sulfur Oxide
Nitric oxide
Hydrocarbons (benzene, terpene, etc.) particulate matter
Water pollutants
The source of these wastes Could Be raw sewage, chemicals, garbage, or fertilizer.
They can be classified as
1. inorganic pollutants
2. organic pollutants
3. Deposits
4. heat
5. radioactive pollutants
6. water pollution by heavy metals
inorganic pollutants
This group is composed of inorganic salts, mineral acids, finely shredded metals or metal compounds, complexes of metals with natural organic matter in water, organometallic compounds, trace elements and acid mine drainage. Some trace elements (a few parts per million) is in the contaminated water.TheSamoe dangerous is heavy metals such as As (V), Cd, Cu, Hg, Cr, etc., and Metalloids As, Se and Sb.
organic pollutants
This group includes, oxygen demanding waste, vegetable waste, nutrients, synthetic organic compounds, pesticides, detergents and oils. Reduction of dissolved oxygen (DO) the index value of the year mainly due to organic substances, for example, sewage, industrial wastes from the food industry, paper mills and tanneries, meat-packing plants, runoff from agricultural fields, etc.
Contaminated water causes great harm to the health of the population. Water Terminal Illness is typhoid and paratyphoid, dysentery and cholera, polio and infectious hepatitis. The production and disposal of pesticides, petrochemicals, detergents etc Pollution compounds the problem.
deposits
Sediments are important custodians of heavy metals. They also contain high levels of organic matter in sediments. The cost increase in precipitation in the water due to the natural process of erosion. It represents the most extensive contamination of surface waters.
heat
Increase of temperature reduction of dissolved oxygen in the water, fish and other aquatic life that affects negatively.ThePromyšlennye, municipal and agricultural waste is major cause.
Radioactive pollutants
Includes pollution radioactive waste from liquid and gaseous fuels, elements, low-level radioactive waste, the various components of radioactive fall out, fission products, radio nucleotides, etc.
Water pollution by heavy metals
Heavy metals are widely used in the textile, leather and metal plating industry, in particular. The use of these metals generates liquid waste, which is usually located continuously without any treatment.
The fuel and energy industry generated 2.4 million tons As, Cd, Cr, Cu, Hg, Ni, As, Se, V, V, and Zn in the year. In Metal Industries adds 0390000 tonnes/year, the metals in the environment. In addition, agriculture contributes to 1.4 million tons/year, 0240000 production generates tons/year and 0.72 million tonnes of waste adds/year
Sources of heavy metals in waste water
Toxic effect of heavy metals
-The increase of cholesterol in the blood of antimony; To reduce blood sugar
Skin damage or problem of arsenic-with circulatory systems, and may increase the risk of cancer
-The increased risk of developing Asbestos malignant intestinal polyps
Cadmium---kidney
Copper-short term exposure: gastrointestinal disorders
The lasting impact: liver or kidney damage
Moderator-of infants and children: delays in physical or mental development of adults: kidney problems; high blood pressure
-The hair or loss
