This episode discusses the issue of microplastics in the Great Lakes, featuring experts from the International Joint Commission (IJC) and universities. Dr. Rebecca Rooney and Eden Hadley explain the standardized definition of microplastics, ranging from 5 millimeters to 1 micron, and their sources, including nurdles, tire wear, and synthetic clothing fibers. The IJC's report highlights the need for standardized monitoring and harmonized methods to assess microplastic concentrations accurately. Recommendations include listing microplastics as a contaminant of mutual concern and promoting life cycle responsibility for producers. Individual actions, such as using microfiber filters in washing machines, can also help reduce microplastic pollution.
