Scientists in the first study of its kind have found microplastic contamination at the bottom of Sydney Harbor, which may pose a threat to the food chain, Australian media reported.

The research by the Sydney Institute of Marine Science tested 27 sites across the harbor, with researchers finding up to 60 microplastics per 100 milligrams of sediment. This was a higher volume than expected even in the cleanest and best-flushed reaches.
Microplastics are tiny fragments and threads of plastic, which are less than five millimeters long. Professor Emma Johnston from the Sydney Institute, who leads the study, told ABC Australia microplastics represent the “emergence of a new contamination in our harbors.”
