NSW platypuses are accumulating the “forever chemical” perfluorooctane sulfonate (PFOS) in very high concentrations.

"The platypus (Ornithorhynchus anatinus) is a semi-aquatic monotreme that occupies a high trophic position in the freshwater ecosystems of eastern mainland Australia and Tasmania. Platypuses are continuously exposed to anthropogenic contaminants including perfluorooctane sulfonate (PFOS). This study examined PFOS concentrations in the livers of deceased platypuses (eight wild; one captive) that were opportunistically collected across NSW over a two- and a half-year period. There was a large variation in PFOS concentrations, ranging from < 1 µg/kg to 1200 µg/kg. This study presents the first report of PFOS contamination in platypuses, revealing their PFOS levels are broadly similar to those found in river otters (Lutra canadensis) and lower than those in American mink (Mustela vison), both which occupy similar ecological niches in freshwater systems. This study raises concerns about the impact of PFOS on platypus health."

"Platypuses are vulnerable to many impacts associated with human activity including hydrological changes, decline in water quality, increase in litter and discarded fishing line, illegal opera house nets (yabby traps) and water contamination...There are no guidelines on what constitutes safe concentrations of PFOS in wildlife."

The biggest likely source of microplastics in California coastal waters? Our car tires
Driving is not just an air pollution and climate change problem — turns out, it just might be the largest contributor of microplastics in California coastal waters.

“No one had looked at all the water rushing off the streets during rainfall events to see whether that had plastics in it...That makes all that driving we do something to think about, not just in the Bay Area, but any setting where there are cars.”

“...It’s about individual behavior change, it’s about more corporate responsibility. Together, we can make a big change.”
