I also found that the microplastic beads were all white and opaque in colors, which fall under the color categories of microplastics commonly found in the North Pacific Central Gyre (NPCG).These colors are similar to those of the area's plankton, a primary food source for surface feeding fish (Boerger et al. 2010). In one study, white, opaque spherules were selectively consumed by 8 species of fish out of 14 species examined microplastics (Carpenter et al, 1972); thus, there is a high likelihood that cleanser microplastics making it to the ocean could be mistaken for plankton by a number of fish species. Though the exact physiological effects of plastic ingestion still require further study, ingestion of plastics may lead to intestinal blockage in smaller fish and risk of polychlorinated biphenyls absorption. (Derraik 2002) The low surface to volume ratio indicates a slower degradation rate, which is concerning, since polyeth- ylene takes years to break down.
