英文摘要: Little is known about the occurrence and fate of synthetic phenolic antioxidants (SPAs) and their metabolites in wastewater treatment plants (WWTPs). In this study, inventory, source, mass loading, and discharge of five SPAs, including 2,6-di-tert-butyl-4-methylphenol (BHT) and four of its metabolites were examined, based on the concentrations determined in wastewater influent, primary effluent, final effluent, suspended particulate matter (SPM), and sludge collected from two WWTPs (denoted as WWTPA and WWTPB) in the Albany area of New York State. The respective median concentrations of sum of SPAs (ΣSPAs = 6 compounds including metabolites) and SPA-metabolites (Σmetabolites = 4 metabolites) were 2455–3330 and 290–465 ng/L in influents, and 1580–1604 and 511–822 ng/L in final effluents. Adsorption to sludge (ΣSPAs ranged as 2420–4680 ng/g dry wt) accounted for ∼1% of the SPA removal. The removal efficiency (RE) for BHT in WWTPs ranged between 62.3% and 76.2%, whereas negative REs were found for SPA-metabolites ([-3020%]-[−65.6%]). WWTP-based mass loading of BHT accounted for ∼4%–10% of the total production volume reported in the USA, whereas ∼1.0% of the annual production of BHT was discharged from WWTP through effluents. BHT present in personal care products was estimated to explain for >91% of the mass loading source into WWTPs. © 2017 Elsevier Ltd Citation statistics:
