Study finds microplastics in Pennsylvania headwaters streams

Microplastics are slivers of plastic that can range in size from a fraction of the width of a single human hair to about the size of an M&M candy cut in half. (Stock photo)

Microplastics can be found everywhere in nature – from drinking water to clouds in the atmosphere – but scientists have yet to fully uncover how severely they impact the environment or the precise factors driving their buildup.
A new study published by researchers at Penn State offers a fresh view of how microplastics traverse and influence watersheds, such as rivers and streams, across Pennsylvania and the world at large.
