Invisible threat: Microplastic contamination discovered on bottom of Sydney Harbour

ABC News Nicole Chettle 22 August 2014

The bottom of Sydney Harbour has been contaminated by widespread microplastic pollution which could be entering the food chain, scientists say.
Professor Emma Johnston from the Sydney Institute of Marine Science said the microplastics, or fragments of plastic less than five millimetres long, represented the “emergence of new contaminants in our harbours and waterways”.
In the first study of its kind, 27 sites were tested across the harbour, with researchers discovering up to 60 microplastics per 100 milligrams of sediment.

Estimates of ‘bioavailable’ mercury — forms of the element that can be taken up by animals and humans — play an important role in everything from drafting an international treaty designed to protect humans and the environment from mercury emissions, to establishing public policies behind warnings about seafood consumption.
