Occurrence and toxicity of perfluoroalkyl acids along the estuarine and coastal regions under varied environmental factors
26 Jan 2021 | Sci Total Environ

Exposure to perfluorooctanesulfonate (PFOS) but not perflurorooctanoic acid (PFOA) at ppb concentration induces chronic toxicity in Daphnia carinata
26 Jan 2021 | Sci Total Environ
The results of this study have great implications for risk assessment of PFOS and PFOA in aquatic ecosystems, given the potential of PFOS to pose a risk to Daphnia even at lower concentrations (1 μg L).
