Comprehensive evaluation of anthropogenic load on environment components under conditions of ferroalloys manufacture

摘要

The article discusses the impact of ferroalloy production on the components of the environment. As an object of research, the Tikhvin Ferroalloy Plant was used.Analysis of social and hygienic monitoring data showed a significant increase in the numberof the disease incidences among the population of the town after the ferrochrome output beginning. The data analysis of air samples, soil and snow in the area of influence of the Tikhvin Ferroalloy Plant are presented. The results demonstrate that the concentrations of metals do not exceed the maximum permissible levels for the air of settlements.However, chemical analysis of the soil and snow samples showed exceeding of the maximum permissible concentrations of chromium and manganese associated with industrial activity of ferroalloys manufacture. The article proposes the recommendations to improve the existing monitoring system.
