Chemicals Management Plan: Wildlife Monitoring and Surveillance Program, aquatic

The Wildlife Contaminants Monitoring and Surveillance Program assesses contaminant exposure in aquatic-associated wildlife across Canada. Biological samples, including eggs and tissues, are collected from gull sentinel species, (such as California gulls, herring gulls, and glaucous-winged gulls) and serve as integrators of contaminant exposure across aquatic food webs. This monitoring focuses on large aquatic systems nationwide, including the Great Lakes and coastal environments, to evaluate spatial and temporal trends in contaminant levels.
