A team in Erlangen used functionalized iron oxide nanoparticles to bind a broad range of PFAS and fluorine-containing microplastics, then remove them with a magnet. In tests on river water, laundry wastewater and a contaminated drinking water source, PFAS fell by 87%, below Germany’s 100 nanograms per liter limit.

Nanopartikeli za sumaku zapunguza PFAS kwenye maji machafu

PHYS

Timu ya Erlangen ilitumia nanopartikeli za oksidi ya chuma zilizoboreshwa kushikilia aina nyingi za PFAS na vipande vidogo vya plastiki vyenye florini, kisha kuviondoa kwa sumaku. Katika majaribio ya maji ya mto, maji ya kuosha na chanzo cha maji ya kunywa kilichochafuliwa, PFAS ilipungua kwa 87%, chini ya kikomo cha Ujerumani cha nanogramu 100 kwa lita.

A 27-year study found an 80-fold increase in loggerhead turtle nesting across three beaches on Boa Vista, Cabo Verde. Researchers link the recovery to habitat protection, anti-poaching patrols, hatcheries, long-term monitoring, and stronger community involvement, despite ongoing threats from climate change and human activity.
