Persistent Organic Contaminants in Dust from the International Space Station
8 Aug 2023 | Environ. Sci. Technol. Lett.
Various compounds, such as PBDEs, OPEs, PAH, PFAS, and PCBs, were discovered in dust from the International Space Station, showing comparable levels to those on Earth; the elevated PFOA concentrations in ISS dust were thought to originate from onboard waterproofing, greases, and nonflammable materials.

4 Aug 2023 | Water Emerging Contaminants & Nanoplastics
This review covers the PFAS sorption onto microplastics, the ecological consequences of ingesting PFAS-contaminated microplastics, and their synergistic effects on aquatic life.
Discussion. Has the human population become an sentinel for the adverse effects of PFAS contamination on wildlife health and endangered species?
2 Aug 2023 | Sci Total Environ
PFAS are detected in wildlife globally, with international efforts needed to restrict PFAS discharges into the environment and to clean up PFAS-contaminated sites in order to protect wildlife from chemical pollution and advance species conservation.
