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were classified in the group of persistent organic pollutants (POPs), and their production was banned and they were withdrawn from use.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.

尽管有生产禁令，多氯联苯目前是如何生产的？它们是否对环境构成风险？

摘要:多氯联苯(PCBs)是由209个同系物组成的基团，其氯原子取代联苯分子的数量和位置不同。由于它们的物理化学性质，它们在工业上得到了广泛的应用。由于多年来大量使用多氯联苯，它们的毒性开始引起人们的注意，并在人类中毒中表现出来。在对多氯联苯进行彻底检测后，被列为持久性有机污染物(POPs)，并被禁止生产和停止使用。虽然多氯联苯不再在工厂生产，但它们仍然可以形成。在这篇文章中，将介绍和解释多氯联苯的意外形成方法。基于文献数据，我们对多氯联苯污染土壤进行了环境风险评估。

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.
