Abstract
Abstract Polychlorinated biphenyls (PCBs) are a group consisting of 209 congeners, differing in the number and site of substitution of chlorine atoms to the biphenyl molecule. Due to their physicochemical properties, they have found wide industry use. As a result of many years of large-scale use of PCBs, their toxic properties began to be noticed as they manifested in poisoning among humans. After thorough testing of PCBs, they were classified in the group of persistent organic pollutants (POPs), and their production was banned and they were withdrawn from use. Although PCBs are no longer produced in factories, they can still be formed. In this article, will be presented and explained methods of accidental formation of PCBs. Based on data from the literature, we performed an environmental risk assessment for PCB-contaminated soils.
期刊介绍:
The journal ENVIRONMENTAL PROTECTION AND NATURAL RESOURCES is a publication which addresses the issues of broadly understood environmental protection and publishes research and review papers. All these articles and papers are peer-reviewed. Interdisciplinary studies published by specialists in various fields present reciprocal relationships between the reactions taking place in the environment which are connected with natural element cycle and at the same time reflect both natural processes and human impacts. Themes of the works also concern socio-economic and technical issues at the UE, national, regional and local levels in the context of sustainable development. The main aim of the journal is to promote high level research in all aspects of environment and natural resources protection.
