Some Ecological Problems of Development of Mineral Raw Materials in Amurskaya Oblast’
Аннотация
The paper considers some ecological problems of the gold-mining enterprise in Amurskaya Oblast’. The investigations have revealed the technogenic pollution of the soil-grounds, air basin, and vegetation under the action of the processing wastes. High concentrations of heavy metals were found in the soils and vegetation in the zone of influence of the plant processing heavy concentrates at a distance of 100 and more meters. They are 2 to 90 times higher than the background values practically in all directions from the technogenic object. High TM concentrations were found also in the soils of building zone. Using the innovation approach we have elaborated the measures for decreasing the pollution negative effect on the habitat. We propose a new way of reclamation of the lands disturbed by the wastes of the mineral raw material processing with the use of the mixed bark-compost of the forest industry wastes.
