It has been established that processes of coal carbonization are accompanied by intensive mercury discharge into the air and soil. The maximum levels of ambient air contamination by mercury are determined 0.5 km away from the source--0.0016 mg/m3, 3 km away from the source--lower than 0.00024 mg/m3. Technogenic area of mercury is almost twice the territory of the plant, and it is stretched along the prevalent direction of the winds. Mercury concentrations at different distances away from the plant were 2.76 mg/kg (0.5 km), 1.97 mg/kg and 0.26 mg/kg. Simultaneous isolation of mercury from coals in the process of coal carbonization is recommended.

Certain aspects of kidney metabolism under a complex organism exposure to mercury have been studied. Different kinds of the heavy metal effect on various chains of metabolism have been established, dependent on the concentration and duration of mercury intake, which is evidence of the many mechanisms and ways of detoxication process. Oxido-reduction enzymes activity is changed due to direct mercury exposure, as well as due to disturbances in boundness of metabolic processes in which these enzymes are involved. The peculiarity of thiolysis mercury effect is the influence of mercury on protein metabolism enzymes--glutamate dehydrogenase (GDG) and NADF-dependent GDG, which is closely related to restructuring of oxidation-reduction kidney functions.
