The RMP has conducted initial studies of microplastic pollution in San Francisco Bay. Findings from a screening-level RMP study of microplastic pollution in our Bay show widespread contamination at levels greater than other U.S. water bodies with high levels of urban development, the Great Lakes and Chesapeake Bay. Wildlife consume microplastic particles; ingestion can lead to physical harm, and can expose aquatic organisms to pollutants like PCBs that the plastics have absorbed from the surrounding environment.

To guide future efforts, the RMP developed a strategy for monitoring microplastics in the Bay. Engaged RMP stakeholders and international experts established management questions and a multi-year plan. We aim to expand knowledge of Bay microplastic pollution to better inform federal, state, and local policymakers currently seeking solutions to this tough problem.
