[Objective]A wide variety of analytical methodologies for the analysis of bisphenol A in sewage waters have been developed in recent years. In this paper we utilized high performance liq-uid chromatography (HPLC) and mass spectrometry (MS) to measure bisphenol A level in the urban sewage waters, that have been treated with Anaerobic-Anox-ic-Oxic (A2/O) technology. [Method]The bisphenol A in the water sample was en-riched using Solid Phase Extraction Cleanert 18 (SPE, C18), followed by HPLC and MS analysis. The flow rate was set at 0.8 ml/min, with acetonitrile as the mobile phase; injection volume was 10 μl each, with a detection preci-sion of 2.5%-6.6%, and a standard re-covery rate of 91.5%-105.1%. Quantita-tion limit of this method was 0.1 ng/L. [Results]Our analysis showed the pres-ence of bisphenol A of all water samples that underwent different treatments from Yangzhou Sewage Treatment Plant, rang-ing from 98.3-106.5 ng/L. The statistical test by one-way ANOVA showed that F=1.258, P=0.235>0.05. [Conclusion]Al-though A2/O technology can decrease environmental estrogens (EEs) to a cer-tain extent, it is not statistically signifi-cant. Hence we conclude that this tech-nology does not implement significant ef-fect on reducing or eliminating EEs.
