The Chesapeake Bay Is Turning Into Plastic Soup

They’re in the oceans, in the Great Lakes, and now it turns out they’re fouling the Chesapeake Bay—microplastics, the remnants of unrecycled products that are damning the world’s water to seemingly eternal pollution.

The presence of microplastics—from broken-up containers to ingredients in bathroom products—has been established in four Bay tributaries by researchers at the University of Maryland, NOAA, and elsewhere. “Microplastics were found in all but one of 60 samples, with concentrations ranging over 3 orders of magnitude (<1.0 to >560 g/km2),” they write in Environmental Science and Technology. “Concentrations demonstrated statistically significant positive correlations with population density and proportion of urban/suburban development within watersheds.”
