Microplastic pollution in the surface waters of the Laurentian Great Lakes, a new paper in the Marine Pollution Bulletin, looks at the prevalence of micro-plastic beads, thought to originate with face-scrub, in the great lakes. These beads pass through water-treatment processing, and have long been suspected in freshwater pollution. The paper has occasioned a pledge from several big cosmetics companies to phase out the use of beads in their products.
