摘要 目的探讨黑龙江省城市重要饮用水水源地受挥发性有机污染物污染的情况。方法2006年5—6月,参照美国EPA524.2方法,用气相色谱-质谱联用仪对黑龙江省6个水源地共15件水样中25种挥发性有机物(VOCs)进行检测。结果方法的精密度和准确度均符合调查方案的要求,回收率为63%~118%,不同组分的RSD≤26%。15件水样中3件检出1,2-二氯乙烷(0.15~0.21μg/L),8件检出三氯甲烷(0.49~2.49μg/L),11件检出甲苯(0.19~3.32μg/L),2件检出苯乙烯(0.23~0.40μg/L),1件检出异丙苯(0.62μg/L),且均未超标。结论本次调查的水源地虽均受到VOCs不同程度的污染,但均未超标。 Objective To investigate the volatile organic compounds (VOCs) contamination in the water sources of city drinking water in Heilongjiang Province. Methods Fifteen water samples were collected from 6 water sources in May to June in 2006. The method in EPA524.2 of the United States was referred and the gas chromatography-mass spectrometry was used to determine VOCs. Results The precision and accuracy of this method could meet the determination. The rates of recovery were 63%-118%, RSD was ≤26%. Five kinds of VOCs in the water samples were detected, they were 1,2-dichloroethane, chloroform, toluene, styrene and isopropylbenzene. Conclusion The investigation shows that the volatile organic compounds are detected in the water sources of city drinking water in Heilongjiang Province.
