5. Environmental contamination by waste of industrial production.

Classification of pollution. There are various kinds of classifications: on types of environments, under polluting factors (lead, mercury, firm waste, etc.), from the point of view of reduction of pollution as a whole, distinguish proof and unstable.

Proof waste - not decaying, do not collapse or decay too slowly. For them there are no natural processes which would decompose them with the same speed from what they act in an environment. These are various substances and poisons (for example, cans).

Such polluting substances collect and biologically amplify on food circuits, incorporating with other substances. These substances can form even more toxic (for example, methyl-mercury).

Ways of struggle:

1. Withdrawal from ecological systems.

2. To stop manufacture of such substances.

3. To forbid emission.

4. To supervise, to not admit a toxic level.

Unstable pollution - the pollution destroyed by biological processes and various physical and chemical transformations.

Organic pollution - sewage. The problem consists in their volume.

Pollution is an adverse change of an environment which entirely or partially grows out human activity, directly or indirectly changes distribution of coming energy, a level of radiation, physical and chemical properties of environment, a condition of existence of the biological environment.

Classification of pollution in view of various factors:

- Physical pollution: power fields (electric, gravitational), influences (electric, magnetic, electromagnetic), inertial forces, corpuscular streams (radiation), thermal pollution, other fluctuations of environment (noise and vibration);

- Chemical pollution:

- Biological pollution:

Microbiological poisoning;

Influences of organisms against each other.

- Aesthetic harm.

Biogeochemical circulation.

Photosynthesis

Circulation _CO2.

Billion т.

Superficial waters are lakes, the internal seas, current mountains.

Soil, underground waters (800) - 0,31 %

Glaciers - 2,15 %

Oceans - 97,2 %

In an atmosphere - 0,001 %

Circulation of phosphorus.

Phosphates are consumed by plants and used for synthesis of organic substances. At decomposition by bacteria of dead organic chemistry phosphates come back in ground and are again used by plants, the part is carried away in the sea and used fitoplankton even on food circuits. The part of phosphorus can return on a land.

Circulation of nitrogen.

The greatest part of nitrogen is concentrated in an atmosphere which great bulk is made with free nitrogen. However free nitrogen in an atmosphere the few, for example, can use bacteria and blue-green seaweed. Nitrogen transforms also into nitrates and nitrites lightning discharges. Nitrates and nitrites circulate in biosphere.

Circulation of carbon.

The source of carbon is used автотрофными by plants.
