ZOE SCHLANGER – “Pellets make up the second most common type of microplastic that we find, second to fragments which break down from things that are bigger,†says Sherri Mason, a plastics pollution researcher at Pennsylvania State University who has published foundational studies on microplastics found in freshwater. She spends much of her time collecting and counting bits of plastic in the environment. “I can go to any beach, give me five minutes and I’ll find a nurdle,†she says. “Along a river, 10 minutes. Once you know what a nurdle looks like you find them everywhere.â€
