According to at least one study of the Great Lakes, Lake Erie came out as the more plastic-polluted than Huron or Superior. In that three-lake study, samples were taken from 21 points in the water. Two samples taken downstream from Cleveland and Detroit account for 85 percent of all plastic gather in the study, according to the Huffington Post.
Relatively little is known about plastic pollution in freshwater sources. The Burning River Foundation funded the three-lake study by 5 Gyres Institute, which expanded the general knowledge base. EcoWatch has the lowdown on where we stand:
Several states and municipalities are interested in banning micro-plastics in consumer products. 5 Gyres is working with a team of advisors to produce model legislation for states to consider.
5 Gyres Institute has launched a microsite as well as an international mobile app, Beat The Microbead, which allows consumers to scan the barcode of personal care products to determine whether they contain plastic microbeads and whether the manufacturer has agreed to remove them.
