Toxic Contaminants

Toxic contaminants harm fish and wildlife in the Chesapeake Bay and pose risks to human health that limit the amount of fish people can consume. Reducing the impacts of toxic contaminants is critical to improving the health of fish and wildlife, thereby improving their recreational value for the public.

Goal: Ensure that the Bay and its rivers are free of effects of toxic contaminants on living resources and human health.


Toxic Contaminants Research Outcome: Continually increase our understanding of the impacts and mitigation options for toxic contaminants. Develop a research agenda and further characterize the occurrence, concentrations, sources and effects of mercury, PCBs and other contaminants of emerging and widespread concern. In addition, identify which best management practices might provide multiple benefits of reducing nutrient and sediment pollution as well as toxic contaminants in waterways.

Toxic Contaminants Policy and Prevention Outcome: Continually improve practices and controls that reduce and prevent the effects of toxic contaminants below levels that harm aquatic systems and humans. Build on existing programs to reduce the amount and effects of PCBs in the Bay and watershed. Use research findings to evaluate the implementation of additional policies, programs and practices for other contaminants that need to be further reduced or eliminated.
