Map of San Francisco Bay showing food dilution threshold risk exceedances based on corrected and rescaled surface water concentrations of microplastics collected using manta trawl. Points represent approximate coordinates of manta trawl sampling locations. Colors represent risk in relation to food dilution thresholds in Mehinto et al. ([42]; re-produced in Table S9). Greater risk can be seen within SFB and San Pablo Bay relative to open-ocean waters outside of the SFB
