| Abstract: | The ethyl acetate extracts of water samples from two urban rivers in Tokyo were analyzed for phenols and aromatic acids by using a combined gas chromatograph-mass spectrometer after separating by solvent extraction and silica gel column chromatography. The following phenols and aromatic acids were identified: pentachlorophenol, bisphenol A, phthalic acid, trimesic acid, p-hydroxybenzoic acid, vanillic acid, syringic acid, p-coumaric acid, and ferulic acid. The presence of o- and m-hydroxybenzoic acids were suggested by mass fragmentography. The sources of those compounds are considered. |
