Abstract:
Objective To observe the pollution states of environmental estrogen-alkyl pheols in tap water of Shenyang. Methods With solid phase extraction and gas chromatography/mass spectroscope (GC/MS) ionic selective methods, the concentration of pollutants of alkyl pheols were measured in 21 tap water samples of water works of Shenyang. Results The main pollutants of alkyl pheols in tap water of water works in Shenyang were 4-t-octyl phenol, nonyl phenol and bisphenol A. The respective maximum concentration was 690.5 ng/L (ranged 29.5-690.5 ng/L), 2 791.6 ng/L (ranged 212.1-2 791.6 ng/L) and 161.0 ng/L (ranged 14.7-161.0 ng/L). The varieties and concentrations of pollutants of alkyl pheols showed a significant difference among water samples from different water works and the seasonal changing of them was demonstrated in the waters made in the same water works. Conclusion The problem on the drinking water contamination with alkyl pheols in Shenyang should be paid more attention by government.
