Published estimates range from 470,000 microplastic particles per square kilometer per day washing into Lake Erie’s western basin to 5.25 trillion particles reported for the North Pacific subtropical gyre. A model estimate places clothing emissions at about 1.1 million particles per day to the atmosphere. In European river waters, reported concentrations span 0.37 to 0.99 micrograms per liter, and those values help explain why results in drinking water studies vary.
