Ecological state of the Khaidarkan Mercury Plant, industrial waste

In the tailings of the Khaidarkan mercury plant, the average content of mercury and other elements is: As - 0.23%; Hg - 0.0046%; Sb - 0.36%. In the territory of the settlement of Chauvay, an excess of mercury concentration relative to the MAC (0.005 mg/l) and MACvr (0.0003 mg/l) was found in samples from the Chatmazar-Sai River (0.0008 mg/l). It is recommended to develop a program of work on the reclamation of the territory; therefore, an in-depth study is necessary to identify the most intensively contaminated areas, determine an appropriate concept and stages of work, and the tasks of environmental restoration. Chemical and biological methods can be used to restore the territory of Khaidarkan. It is necessary to prevent free access of the local population, as well as wild and farm animals, to hazardous areas.
