New study reveals extreme levels of microplastics in San Francisco Bay

Oakland North

A study published in early October by two Bay Area environmental research institutes has raised alarm among local environmentalists after it found that the San Francisco Bay is highly polluted with microplastics, tiny plastic particles... Sejal Choksi Chugh, executive director of Baykeeper, a nonprofit that works to monitor and improve the health of the San Francisco Bay, said she was surprised, too, that so many microparticles were coming from runoff and possibly from tires. “That’s a new source that I hadn’t considered,” she said.
