Assessment of Technogenic System Impact on the Environment and Technospheric Safety for Mineral Development in Amurskaya Oblast
Abstract
The article presents the results of the study to assess the impact of the tehnogenic system on the environment and technospheric protection during mineral resources development in the Amurskaya oblast (region). High ecological toxicity of tailings, contributing to the deterioration of the life environment. According to the authors’ research, here air pollution can be attributed to high level. At all pilot sites MPC level exceeding in soils and vegetation for arsenic, chromium, manganese, copper, zinc, lead, cobalt, antimony was determined. Analyzing total risk indexes for substances effecting the same systems and organs, the highest value was found for the group of substances affecting the human respiratory organs: suspended particles, sulphur dioxide. The measures reducing the impact of mineral processing wastes on the environment and the health of the mining settlements population in Khabarovsky Krai were developed.
