Paint Dust Covers the Upper Layer of the World's Oceans

sciencehabit (1205606) writes Even when the sea looks clean, its surface can be flecked with tiny fragments of paint and fiberglass. That's the finding from a study that looked for plastic pollution in the uppermost millimeter of ocean. The microscopic fragments come from the decks and hulls of boats, and they could pose a threat to zooplankton, an important part of the marine food web.
