Microplastic pollution discovered in St. Lawrence River sediments

18 septiembre 2014

Microplastics have been discovered widely distributed across the bottom of the St. Lawrence River, the first time such pollutants have been found in freshwater sediments. The microbeads likely originate from cosmetics, household cleansers, or industrial cleansers, to which they are commonly added as abrasives. Owing to their small size and buoyancy, they may readily pass through sewage treatment plants. Microplastics are a global contaminant in the world’s oceans, but have only recently been detected in the surface waters of lakes and rivers.
