Study examining spread of microplastic debris through aquatic environments

SCCWRP and its partners have launched a three-year study to examine how microplastic debris is transported via waterways to the coastal ocean and what happens to this pollution once it reaches the contintental shelf.

The study, launched in November, will quantify levels of microplastics in the Los Angeles and San Gabriel Rivers, as well as in the treated wastewater effluent that is discharged into these rivers.

A computer model will be used to investigate what happens to this pollution upon reaching the San Pedro Shelf; the goal is to illuminate risks to pelagic vs. benthic habitats.
