北极黄河站科学考察（2017年）沉积物多氯联苯有机污染物分析数据

持久性有机污染物是一类在环境中普遍存在但难以降解、可远距离迁移、具有很强的生物和生态毒性、并能随食物链在动物和人体中不断富集放大的物质。监测和分析持久性有机污染物在不同环境介质中的赋存水平，预测持久性有机污染物的污染趋势，对其来源进行解析并评估它们潜在的生态风险，可为相关政策的制定及环境污染的预防和治理提供基础数据。
本数据为北极黄河站科学考察（2017年）沉积物多氯联苯持久性有机污染物分析数据，数据共包括8个站位号（8条记录）。

Persistent organic pollutants (POPs) are a group of substances ubiquitous in the environment, which are recalcitrant to degradation, capable of long-range transport, possess potent biological and ecotoxicological effects, and can undergo continuous biomagnification along food chains to accumulate in animals and human bodies. Monitoring and analyzing the occurrence levels of POPs in various environmental matrices, predicting their pollution trends, identifying their sources, and assessing their potential ecological risks can provide fundamental data for the formulation of relevant policies as well as the prevention, control and governance of environmental pollution.
This dataset contains analytical data on polychlorinated biphenyls (PCBs, a type of POPs) in sediments collected during the 2017 scientific expedition at the Arctic Yellow River Station. The dataset includes 8 sampling stations, corresponding to 8 individual records.
