中文摘要：

研究建立了利用顶空气相色谱法测定水源地水中多种苯系物的方法，包括（苯、甲苯、乙苯、邻二甲苯、间二甲苯、对二甲苯、苯乙烯和异丙苯），该方法具有简单、快速和经济、准确等特点。研究结果表明，水源地水源中未检出苯系物，但是蓄水性水源地污染风险高于流动性水源地，本研究为水质和环境工作者提供基础依据和风险性评估。

英文摘要：

The method for determination of water and a variety of water sources of BTEX using headspace gas chromatography was established , including benzene, toluene, ethylbenzene, o-xylene, m-xylene, p-xylene, styrene and cumene.The method was simple , fast and economical , accurate and so on.The results showed that the water was not detected in ground water BTEX , but the water was higher than the risk of contamination of water sources of liquidity sources.This study provided basic evidence and risk assessment to the water quality and environmental workers .
