Abstract:
Objective To assess the level of environmental hormone (EH) in Lanzhou reach of the Yellow River and to find the pollutant sources and pollution routes. Methods Solid phase extraction (SPE), gas chromatography-mass spectrophotometry (GC-MS) and gas chromatography (GC-FID) were employed to determine EH in the water samples. Results 10 kinds of EH were detected, of which 6 were the priority control pollutants determined by the American EPA and 6 were predominant pollutants in China. 10 EH detected in Lanzhou reach of the Yellow River included naphthalene, phenanthrene, DBP, DEHP and benzothiazole and the detection rates of the five EH were 40%, 60%, 100%, 100% and 20% respectively. Conclusion The predominant environmental hormone pollutants in Lanzhou reach of the Yellow River are PAEs, PAHs, heterocycles, phenols and the main source of these pollutants is the waste water of petroleum chemical industry.
