In a study, we see that plastic microparticles are contaminating the world's shorelines and that much of the pollution appears to come from fibers from washing polyester clothes. The same study also took samples from ocean beaches. Five samples were taken from each of 18 different shorelines worldwide, for a total of  90 samples of size 250 mL. The mean number of plastic microparticles found per 250 mL of sediment was  18.3 with a standard deviation of  8.2 .
