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.
