► We determined C3–C14 PFAs in sewage sludge from 25WWTPs in Shanghai, China. ► PFAs pollutants were ubiquitous in sludge with the ∑PFAs range of 126–809ngg−1. ► Unlike previous studies, PFOA was dominant and much higher than those reported. ► Concentrations of short-chain PFAs (<C6) in sewage sl...
