IDENTIFICATION OF AROMATIC HYDROCARBONS AND POLYCHLORINATED BIPHENYLS FROM SOLID WASTE LANDFIL

Abstract

Organic and inorganic wastes are solid wastes why are generated because urban society rapidly increasing production of artifact, becoming useless or unwanted. Rapidly this thing lost their value, became waste and a major cause of pollution. Solid waste disposals represent a significant source of polychlorinated biphenyls and aromatic hydrocarbons released into the environment. The biggest problem of waste disposal is leachate. Leachate is primarily result of precipitation that penetrates through the soil and waste, enters the composition of groundwater and contaminates it. The result is soil pollution with polychlorinated biphenyls and aromatic hydrocarbons. Because these pollutant cannot be biodegraded could lead to serious consequences. Polychlorinated biphenyls and aromatic hydrocarbons have a huge negative impact on the environment. these pollution because of their chemical nature represent a potential risk for the environment, animals and people. Numerous studies have shown their negative impact when they reach the environment. The concentration of aromatic hydrocarbons and polychlorinated biphenyls was examined after sampling from open dumpsite at the territory of the city of Leskovac, Republic of Serbia collected around solid waste. Aim is to understand contamination caused by leachate migration from mentioned dumping. These analysis and soil research is an important process that includes the examination of soil quality, as well as the detection of potentially harmful substances and pollution. This paper aims to determination of the quality of the soil, detection of contamination and identification of hazard and harmful substances in the soil samples. Presents the results of soil sampling and laboratory analysis at a closed landfill in the territory of the city of Leskovac in accordance with the the Regulation on maximum permissible values of pollutants, of harmful and hazardous substances in the soil (Official Gazette of RS, no. 30-2018 and 64-2019). Based on the test results, given in Regulation on maximum permissible values polluting substances, harmful and hazardous substances in the soil (Official Gazette of the RS, no. 30-2018 and 64-2019), it was determined that concentrations of aromatic hydrocarbons were detected in the analyzed soil samples and polycyclic aromatic hydrocarbons. However, the obtained values of these parameters do not exceed the maximum permissible values, but their existence and contamination can lead to serious consequences. The paper provides useful information for further planning of remediation measures, closed landfill management and environmental protection.
