A Antimicrobial compounds measured in wastewater influent by non-target UPLC/MS/MS screening. The six antibiotic/antifungal compounds with the greatest peak areas for both WWTPs across all samples were: azithromycin (MLS), ciprofloxacin (quinolone), clarithromycin (MLS), methylparaben (anti-fungal), thiabendazole (anti-fungal and anti-parasitic), and trimethoprim (diaminopyrimidine). B Concentrations of quaternary ammonium compounds (QACs) in wastewater influent. QAC abbreviations: Benzyldimethyldodecylammonium chloride (C12-BAC), benzyldimethyltetradecylammonium chloride (C14-BAC), benzyldimethylhexadecylammonium chloride (C16-ABAC), octyl decyl dimethyl ammonium chloride (C20-DDAC), dioctyl dimethyl ammonium chloride (C18-DDAC), and dodecyl dimethyl ammonium chloride (C22-DDAC).
