Study to build foundational understanding of microplastics pollution in two major rivers

SCCWRP and its partners are initiating a three-year study to identify the levels, types and distribution of microplastics in two major Southern California rivers – part of a broader effort to inform the development of a statewide strategy for managing microplastics pollution.

Sampling for the study, which is scheduled to kick off in January, will encompass water, sediment and aquatic organisms at multiple sites along the Los Angeles and San Gabriel Rivers.

To analyze the water, sediment and tissue samples, researchers will utilize cutting-edge microplastics measurement methods that are being standardized through an ongoing, international method intercalibration study facilitated by SCCWRP.

The study workplan is expected to be finalized in December.
