Microplastics – Deposition in Remote Areas

According to a June 12, 2020 report in Science Magazine https://science.sciencemag.org/content/368/6496/1257 “... even the most isolated areas in the United States—national parks and national wilderness areas accumulate microplastic particles after they are transported there by wind and rain … [The authors] estimate that more than 1000 metric tons per year fall within south and central western U.S. protected areas … Because plastics are persistent, they fragment into pieces that are susceptible to wind entrainment … urban centers and resuspension from soils or water are principal sources for wet-deposited plastics. By contrast, plastics deposited under dry conditions were smaller in size, and the rates of deposition were related to indices that suggest longer-range or global transport … These findings should underline the importance of reducing pollution from …” improperly discarded plastic #Microplastics #PlasticWaste #SingleUsePlastic #PlasticPackaging
