"Surprising Study Reveals Alarming Pollution Levels on International Space Station"

A study has found that concentrations of toxic contaminants in dust on the International Space Station (ISS) exceed those found in floor dust in many American homes. The levels of organic pollutants in ISS dust samples were higher than the median values found in US and Western European homes. Contaminants identified in the "space dust" included flame retardants, persistent organic pollutants, and substances classified as human carcinogens. The researchers suggested that careful material choices in the design and construction of future space stations could help exclude many contaminant sources.
