Summary

Researchers investigated how biofouling affects Daphnia magna ingestion rates of microplastics from wastewater effluent and fresh surface water. They found that D. magna consumed significantly more biofouled microplastics than virgin microplastics, with the effect seven times greater for surface-water biofilm versus a twofold increase for effluent biofilm, suggesting biofouling substantially increases plastic uptake by freshwater zooplankton.

The influence of biofouling on zooplankton ingestion rates of plastics in freshwater environments has received limited attention. We investigated how biofouling of microplastics in wastewater effluent and in fresh surface water influences Daphnia magna's microplastic consumption. The differences in ingestion of the biofouled as compared with the virgin microplastics were higher for the surface water by a factor of seven compared with a factor of two for the effluent. The intake of biofouled microplastics by D. magna was higher compared with virgin plastics, but the reason for this preference should be further investigated.
