Organochlorine insecticides and mercury in predatory bird livers (PBMS)

Data comprise concentrations of organochlorine insecticides and mercury in sparrowhawk, kestrel and heron livers taken during post mortem from deceased birds of prey sent into the Predatory Bird Monitoring Scheme (PBMS) by the public. The data are presented as micrograms of contaminant per gram of liver tissue (wet weight). The PBMS is a long-term, national monitoring scheme that quantifies the concentrations of contaminants in the livers and eggs of selected species of predatory and fish-eating birds in Britain. Levels of contaminants are monitored to determine variations between species and regions, changes over time and effects on individual birds and their populations. The Scheme is currently funded by CEH, Natural England, the Environment Agency (EA) and the Campaign for Responsible Rodenticide Use (CRRU).本数据集涵盖从公众提交至猛禽监测计划（Predatory Bird Monitoring Scheme，PBMS）的死亡猛禽尸检肝脏样本中检出的有机氯杀虫剂与汞浓度，涉及物种包括雀鹰、红隼与鹭。数据以每克肝脏组织（湿重）中污染物的微克数为单位进行呈现。猛禽监测计划（PBMS）是一项长期国家级监测方案，旨在定量测定英国境内选定猛禽与食鱼鸟类的肝脏及卵中的污染物浓度。该方案通过监测污染物水平，以探明不同物种与区域间的浓度差异、随时间推移的浓度变化，以及污染物对个体猛禽及其种群的影响。本计划目前由生态与水文研究中心（CEH）、英格兰自然署（Natural England）、环境署（Environment Agency，EA）以及负责任杀鼠剂使用运动（Campaign for Responsible Rodenticide Use，CRRU）资助。
