This study aimed at demonstrating the influence of differential electroplating wastewater treatment processes on the occurrence of legacy per- and polyfluoroalkyl substances (PFAS) from production discharge to wastewater treatment effluent. Here, the wastewater and sludge samples were collected from one electroplating industrial park (EIP) and four electroplating plants (EPs 1-4), which equipped with centralized wastewater treatment plant or distributed wastewater treatment facilities. Among them, EIP and EP-1 respectively gather four and three different production discharges, while other EPs have one type. Results indicated that the total concentrations of thirteen PFAS (∑
