Nowadays pollution of the environment is an actual problem. Persistent organic pollutants (POPs)are a group of toxic chemicals and poorly digested in water, able to accumulate in the fat layer of a livingorganism. Persistent organic pollutants include 12 toxicological substances that adversely affect humanhealth and the environment. Determination of soil pollution level of PCBs in the urban ecosystem. It wasfound that 80% of PCB waste registered in Kazakhstan, and 1200 hectares of land were contaminatedwith PCBs. The study was conducted in Ust-Kamenogorsk in the directions of «Environmental ProtectionResearch» from 2003 to 2009. The results of this study show that today the problem of accumulationof PCBs in the soil layer in Ust-Kamenogorsk is becoming topical. The results of the study are widelyused to identify priority areas for persistent organic pollutants, including polychlorinated biphenyls,for scientific assessment of the environmental situation in the East Kazakhstan, South-East region andto attract attention of those who have the right to make decisions on the issue of persistent organicpollutants. The soil samples were washed with n-hexane in a soxlet apparatus and the content of polychlorobiphenyl in gas chromatography «MASTER GC» using «Dexsil L2000DX», analyzed according tostate standard 17,4,3,01-83. An overview of the pollution of PCBs in Kazakhstan was carried out withinthe framework of the project «Pollution of IVF and other regions of PCBs: control over the territory andverification of PCBs – problem solving». From the study, the soil and trichlorobiphenyl residues from theUst-Kamenogorsk Condenser Plant (UКСР) were stored in the Ust-Kamenogorsk storage compartmentand the plant was transferred to another alternative technology. Today it is known that the onset of anydisease in a young organism begins with the influence of the external environment, that is, the study ofthe level and causes of the adverse environmental effects, that is persistent organic pollutants that affectthe health, growth and development of a young organism that has undergone various adaptation factors.The results of the research showed that the regional health department became an additional material inthe study of the health and physical development of the young organism and scientifically evaluated theenvironmental situation in Kazakhstan and studied the problem of persistent organic pollutants and usedit as an additional opportunity for making legal decisions.Key words: Polychlorobiphenyl, persistent organic pollutants, pesticides, toxicology
