New insights into the occurrence and fate of per-and polyfluoralkyl substances in textile dyeing wastewater along different treatment processes to receiving river

Key Points

• To explore how per-and polyfluoroalkyl substances are present and processed in textile dyeing wastewater.
• Analyzed wastewater samples from textile dyeing facilities
• Examined the impact of different treatment processes
• Investigated the fate of PFAS during treatment stages
• PFAS concentrations varied significantly across treatment processes
• Some treatment methods were more effective at reducing PFAS levels
• PFAS were detected in the receiving river, indicating environmental contamination
