Microplastics and microfibers in San Fransisco Bay
Microplastics (plastic particles smaller than 5 mm) have gained global attention as a pervasive and preventable threat to the health of aquatic ecosystems. 7 trillion bioplastics enter the Bay Area annually through stormwater. This is 300x more than is found in treated waste water. Microplastic levels in the bay's surface waters are higher than any other urban embayments.
