Distribution characteristics and source of BTEX in groundwater of Eastern Foshan, Guangdong
摘要
Abstract
In order to determine the distribut ion characteristics of BTEX ( including Benzene, Toluene, Et hylbenzene, o-Xylene, m-Xylene, and o-Xylene) in groundw ater, 37 groups of groundw at er sam ples and 10 surface wat er samples collected from the east-ern area of Foshan in Guangdong during 2005 to 2008 were tested using t he gas chromatography and mass spectrum ( GC/ MS) . The results showed that the detection rate of BTEX is 24. 32% in groundw ater, and the total BTEX concentrat ion is low er than 27. 2 μg/ L. Among the six kinds of BTEX, T oluene had t he highest detection rate ( 24. 32% ) and detect ion value ( 10. 7 μg/ L) , which was follow ed by Benzene w ith the detection rate of 10. 81% and detection value of 9 μg/ L respect ively. Ethylbenzene, p-Xylene, m-Xylene, and o-Xylene w ere only detect ed in a few of samples, and the concentrations in groundw ater did not exceed the st andard. Most of samples with BT EX w ere dist ributed in Nanhai area, and most of groundwater samples w ere detected con-taining only one kind of BTEX. There w as an obvious correlation bet ween the BT EX distributions in groundw ater and surface water, and Toluene and Benzene were the dominating BTEX in surface water. The infiltration of surface water containing BT EX is an important source of BTEX in groundw ater of the eastern area of Foshan.关键词
