Polychlorinated biphenyls (PCBs) are included in the persistent organic pollutants designated by the Stockholm Convention and are hazardous compounds both for the environment and public health. The aim of this study was to determine the level of environmental pollution of PCBs in the Perm, in soil and biota (European pied flycatcher), and to analyze whether its presence was the cause of cancer and congenital malformations in the population. Soils in the study area had PCB concentrations of 101.87 µg/kg in the Industrialniy District and 27.81 µg/kg in the Leninskiy District of the Perm in 2005. The chemical composition of the individual PCBs and PCB groups were the same in the soils of both regions. The blood of nestlings of the European pied flycatcher raised in the Industrialniy District contained 9.61 ng PCB/ml, while those in the Leninskiy District had 5.64 ng PCB/ml in 2005. A linear correlation was established between the PCB contamination of soils and PCB contamination of pied flycatcher nestling’s blood, and inverse linear correlation was established between the content of PCB in the blood of nestlings and the success of breeding of the pied flycatcher in Perm. An epidemiological analysis revealed a high incidence of cancer among the human population of the Industrialniy and Leninskiy districts (371.7 and 376.85 cases per 100,000 population, mean for the 2003–2018, respectively), which exceeded the figure for the whole of Perm (350.77 cases per 100,000 population, mean for the 2003–2018). The incidence rate of congenital malformations in Perm for the study period was 48.51 per 1000 human births. However, a decrease in the concentration of PCBs in soil and biota over a 15-year period (2005–2019) to the less than the detection limit did not lead to a decrease in the incidence of these diseases. Probably, PCB contamination was not the main cause of oncological diseases and congenital malformations in the population of the study area.

《斯德哥尔摩公约》指定的持久性有机污染物中包括多氯联苯（PCB），对环境和公众健康都是有害化合物。这项研究的目的是确定彼尔姆，土壤和生物区系（欧洲斑s）中多氯联苯的环境污染水平，并分析其存在是否是人口中癌症和先天性畸形的原因。研究区域的土壤中，彼尔姆工业区的PCB浓度为101.87 µg / kg，彼尔姆列宁斯基地区的PCB浓度为27.81 µg / kg。两种土壤中各个PCB和PCB组的化学成分相同地区。在Industrialniy区饲养的欧洲斑fly的雏鸟血液中含有9.61 ng PCB / ml，而2005年列宁斯基地区的PCB含量为5.64 ng / ml。在土壤中的PCB污染与斑fly雏鸟血液中的PCB污染之间建立了线性相关，并且在血液中PCB含量之间呈反线性关系。刚孵出的雏鸟以及在彼尔姆繁殖的the蝇的成功繁殖。一项流行病学分析显示，在Industrialniy和Leninskiy地区的人口中，癌症的发病率很高（每10万人口中分别为371.7和376.85例，2003-2018年的平均值），超过了整个彼尔姆的发病率（350.77例）每十万人口中，2003-2018年的平均值）。在研究期间，彼尔姆先天性畸形的发生率为每1000例婴儿48.51例。然而，在15年内（2005-2019年），土壤和生物区系中PCBs的浓度下降到检测限以下，并没有导致这些疾病的发生率下降。PCB污染可能不是研究区域人口中肿瘤疾病和先天性畸形的主要原因。
