Toxicological Response of Chironomus dilutus in Single Chemical and Binary Mixture Exposure Experiments with Six Perfluoralkyl Substances
13 Apr 2021 | Environ Toxicol Chem
PFOS was found to be the most toxic PFAS to aquatic life and suggests that PFOS could be more toxic to freshwater insects than previously reported.
