Identification and quantification of chlorinated bisphenol A in wastewaterfrom wastepaper recycling plants

Chlorinated derivatives of bisphenol A were detected in the final effluents of eight paper manufacturing plants in Shizuoka, Japan, where thermal pape r and/or other printed paper is used as the raw material. Their amounts wer e determined by gas chromatography/mass spectrometry (GC/MS) after treatmen t with N,O-bis(trimethylsilyl)trifluoroacetamide, and ranged from traces to 2.0 mug/l. They are likely produced by chlorination of bisphenol A, which was released into the effluents from the pulping process of wastepaper, dur ing or after bleaching with chlorine.
