Conclusions: •First report of PPCPs in Antarctic coastal waters and sewage effluent •PPCP concentrations were comparable to studies in temperate climates •WWTPs are ineffective at removing PPCPs •Stations with no treatment likely to release higher concentrations •WWTPs are potentially not the only sources of PPCPs into Erebus Bay •Larger geographic. Implications: •Further assessment of organic micropollutants in Antarctic ecosystems is required •Protocols for use of PPCPs in Antarctica need to be developed •Upgraded or new waste water treatment plants should be designed to remove organic micropollutants including PPCPs
