an absolute or relative magnitude of concentration of the pollutants in the environment.

an indicator signaling about availability, cumulation, variation of quantitative parameters or qualitative composition of pollutants in an environment; it can be physical, chemical and biological.

one of the types of physical pollution of the environment characterized by a periodic or long-term heightening of its temperature above its natural level.

The redundant use of artificial light in the open air can cause dazzling or disturbance at night, can generate a feeling of malaise, of psychological disorders and stress. It also disrupts the biorhythm of flora and fauna.

environmental pollution near to polluters (plant, construction, opencasts), not extended to considerable territories. Collection of L.p. can form regional pollution.

penetration into ecosystem of alien to it pollutants in concentrations exceeding the background ones.

introduction in ecosystem of sources of physical energy, expressing in deviation from a norm of its temperature-power, wave, radioactive and other physical characteristics.

increasing of concentration of those or other matters or energy above natural (background or tolerance limits of norms), and also introduction of matters, organisms and power sources, alien to a landscape, as owing to their anthropogenous, so natural (volcanism, natural migration of matters) factors.

1. a point of the pollutant discharge

2. economic or natural object manufacturing the pollutant (see Contaminant)

3. region where a pollutant comes from.

introduction into ecosystem of abiotic alluviums alien to its nature disturbing its natural functioning.

a territory, within the limits of which the environment is damaged as aresult of dissipation of the pollutants, arriving from organized and unorganized sources of outbursts.

A period of abnormally high concentration of air pollutants, often due to low winds and temperature inversion that can cause illness and death. In cases of accidental releases of airborne gases and particulates, special organizational measures are taken by authorities to cope with the situation to alleviate the consequences. At periods of high air pollution concentrations many cities stop traffic for certain periods until the high level reduces.

Pollutions coming from the farming wastes, including runoff and leachate of pesticides and fertilizers; erosion and dust from ploughing; improper disposal of animal manure and carcasses; crop residues, debris and air pollution. Smells and odour from agricultural activities can also be considered as agricultural pollution.

a territory adjoining the sources of environmental impact, places of arranging and burial of wastes or irrational usage of natural resources, for which negative changes of environmental condition are characteristic.

Usage of the processes, practices, materials or products that allows to avoid, reduce or control over the pollutions and may include recycling, treatment, reprocessing changes, control mechanisms, efficient utilization of resources and material substitution.

Pollution that crosses the borders of states or territorial and administrative units, for example, pollution of rivers or contamination of air (acid rain).

Any non-stationary source of pollution (such as cars, trucks, motorcycles, buses, air-crafts, etc).
