Technogenic impact of mining industry on environment in karaganda region of republic of kazakhstan

Abstract

This paper is devoted to evaluation of a technogenic impact of the mining industry on the environment in effecting of a gold deposit in soils. This study determined a content of 27 chemical elements in slime of the tailings and sampling materials of overburden; the analysis of structure of emissions in the atmosphere from the organized sources. It was noted that tailing dump contents barium, boron, ferrum, manganese, strontium, phosphorus, zirconia, and overburden rock has titanium. The emissions are such as sulfur oxides, nitrogen oxides, carbon oxide, ferrous oxide and the inorganic fines. Based on the received results a total soil pollution index (Pt=20.34) was calculated that it characterizes an ecological soil conditions as hazard. In order to evaluate the soil conditions in the sanitary protection zone (SPZ) the analysis of a soil pollution level in eight cardinal directions on the SPZ border of an enterprise was performed with the six-year research results. It was found that the minimal pollution indexes (Pt) are characteristic for soils in southwest (12.53), east (13.13), northern (13.36) and the northwest (13.58) directions from the productive facilities. The high contribution to indexes is made with the gross arsenic contents (6.90, 6.93, 5.38 and 6.75) within maximum permissible concentration (MPC), respectively. The high soil pollution indexes (Pt = 32.97 and 26.06), corresponding to a critical pollution level, were determined in soils of the southeast and western borders in the sanitary protection zone. In addition, this paper demonstrates an analysis of the flora and fauna condition in a studied area and impact of the analyzing industrial facility on it. The research result can be applied to develop the maps for the estimating potential inertial landscape stability to different types of pollution and erosive hazard.
