“Tiny bits of plastic pose big threat” – Grace Chua in The Straits Times, 24 Jun 2014 [pdf]
Although the relationship between a microbead’s size and its environmental impact has not been fully studied, Associate Professor Obbard says studies done with his students a decade apart have found that this pollution is present, and increasing, all over Singapore.
Plastic particles were detected in beach sediment at four of seven beaches – St John’s Island, Pasir Ris, East Coast Park and Kallang River, in seawater at the Republic of Singapore Yacht Club and Kranji, and in all seven mangrove habitats sampled at Berlayar Creek, Sungei Buloh, Lim Chu Kang and Pasir Ris.
While little work has been done on what level of microplastic might be hazardous, scientists are concerned because it is so widespread.
