An Australian community for everything from your backyard to beyond the black stump.

Topics may include Aussie plants and animals, environmental, farming, energy, and climate news and stories (mostly Aus specific), etc. New related communities will be split off when required, think like subcommunities that exist on that other platform.

Trigger Warning: Community contains mostly bad environmental news (not by choice!). Community may also feature stories about animal agriculture and/or meat. Until tagging is available, please be aware and click accordingly.

Bit by bit microplastics from tyres are polluting our waterways (news.griffith.edu.au)

Stormwater runoff which contains a mixture of sediment, chemical, organic and physical pollutants, is a critical pathway for microplastics to washed off from urban environments during rain and into local aquatic habitats."But to date, our knowledge of the amount of microplastics in urban stormwater, particularly tyre wear particles, is limited, as is the potential strategies we can use to minimise this source.

"Our study quantified and characterize microplastics and tyre wear particles in both stormwater runoff and sediment of stormwater drainage systems in Queensland," said co-author Professor Fred Leusch, who leads the Australian Rivers Institute's Toxicology Research Program.

"The device is a bag made of 0.2 millimetre mesh which can be retrofitted to stormwater drains. Although originally designed to capture gross pollutants, sediment, litter and oil and grease, it significantly reduced microplastics from raw runoff, with up to 88% less microplastics in treated water which had passed through the device."

Sediment samples collected from the inlet and outlet of a constructed stormwater wetland contained between 1450 to 4740 particles in every kilogram of sediment, with more microplastics in the sediment at the inlet than the outlet, indicating the wetland's ability to remove them from stormwater.

"Our findings show that both constructed wetlands and the stormwater capture device are strategies that could be potentially used to prevent or at least decrease the amount of microplastics tyre wear particles being transported from stormwater into our waterways."

Cool. What's the solution?

Hover boards. I’ve been waiting since i was a kid. It should be coming right?
