Chemical pollution of nature and its consequences

Under pollution understand introduction of foreign substances that are not typical in normal conditions, as well as the excess of the normal concentration of a chemical agent.At present, the nature of the pollution is a problem of global scale, which for many years and even decades trying to solve all the developed countries.Unfortunately, the constant increase in the rate of technological progress, processing of minerals, preserved popularity steel industry, expansion of cities and other human factors only aggravate the negative impact of human civilization on wildlife.

Determination

types of pollution are often divided into several groups according to the type of exposure: the physical, biogenic, news and many others.But one of the most dangerous and destructive consequences of bearing species is considered chemical contamination of the environment.Under this definition means any occurrence of chemicals in non-smoking areas are.It is now obvious that the results of the direct influence of man

on his environment throughout its history are negative.And on the first lines of this list should be the nature of chemical pollution.

sources of pollution

consequences of anthropogenic influence reflected not only on the state of the natural environment, but also to ourselves.Often the chemicals enter the body and accumulate in it, becoming a cause of serious injury, aggravate and exacerbate existing chronic diseases.It was also shown that prolonged chemical exposure (even in low concentration) has on living creatures dangerous mutagenic and carcinogenic effects.

Intensive toxic influence of heavy metals can have: a special danger is that they are virtually eliminated from the body.Such substances can accumulate in plant tissues, which is then fed animals.Well, at the top of the chain may well be the man.The latter, therefore, runs the risk of being subjected to the maximum the negative consequences of the impact of toxins on the body.

other hazardous substances Pollution of nature, is dioxins, which are produced in large quantities during the production of pulp and metallurgy industries.Added to exhaust fumes of cars operating on internal combustion engines.Dioxins are dangerous for people and animals.Even in small amounts, they may cause damage to the immune system, kidney and liver.

is currently no longer appear new synthetic compounds and substances.And to anticipate the consequences of their destructive impact on the environment is virtually impossible.Also, not to mention human agricultural activities in many countries, it reaches such tremendous volume that provokes pollution of nature faster than heavy industry all together.

How to protect the environment from the negative effects?

The main measures to combat these processes should be ranked as follows: strict control over the generation of wastes and their subsequent disposal, improvement of technology to bring them closer to the model without waste, increasing the overall efficiency of production and reliability.A huge role is played by preventive measures, as in this case, it is much easier to prevent the problem than to deal with its consequences.

Conclusion It is clear that they are far from the days when our influence on nature even stop constantly exacerbated, not to mention the significant reduction of harm.This issue should be addressed at the highest level, the efforts of all the inhabitants of the Earth, rather than individual countries.Moreover, the first steps to have already been made decades ago.Thus, in the seventies, scientists first published the information on the destruction of the ozone layer.It was found that the aerosol cans and air conditioners are a source of environmental release of atomic chlorine.Last entering the atmosphere, react with the ozone and destroys it.This information prompted many countries to agree on mutual reduction of hazardous production.
