Pollution-trawling voyage finds ocean's plastic 'soup'

If you trawl a fine mesh net through any of the globe's five subtropical gyres – giant ocean vortexes where currents converge and swirl unhurriedly – you will haul on deck a muddle of brown planktonic goop, the occasional fish, squid or Portuguese man-of-war – and, almost certainly, a generous sprinkling of colourful plastic particles, each no larger than your fingernail.
Every flake of plastic cup or shard of toothbrush handle is a sponge for persistent organic pollutants (POPs) – potentially hazardous compounds that do not degrade easily and cling to any hard surface they find. The fate of all this plastic determines not only the health of marine life, but also our own; if fish are feasting on these toxic morsels, then we probably are too.    link
