Recent winter storms washed microplastics into San Francisco Bay, studies show
Walk along Damon Slough in Oakland and you’re likely to see trash heading towards San Francisco Bay. David Lewis of the environmental group Save the Bay, says much of it comes from the nearby 880 freeway and local storm drains. … And experts say the pollution you can actually see is only part of the threat. Floating along side, often invisible to the naked eye, are microplastics. They’re tiny particles, that can come from clothing, cigarette butts, and even the rubber from car tires.
