The PBMS is a unique long-term, national monitoring initiative designed to measure the levels of contaminants in the livers and eggs of selected predatory bird species across Britain. Our aim is to determine the causes and effects of variations in these contaminants between species and regions, and how they change over time. These findings can provide vital information on the risks to vertebrate wildlife and people, and how to mitigate them.
The PBMS provides evidence of the effectiveness of mitigation strategies, including those incorporated into national and international chemicals management programmes.
