摘  要:
通过对河水、河床底泥、岸边土壤剖面、地下水样品的测定,对太行山前平原磁河地区地下水中苯系物在水土系统中的分布特征进行了研究。结果表明,各种介质中的苯系物(苯、甲苯、乙苯、二甲苯)具有一定的相关性,与河不同距离和不同深度土壤中的苯系污染物主要来自污水河。但是,由于有机污染物在土壤中的吸附等作用过程,有机污染物浓度在一定的距离内迅速降低。在河岸边不同距离的地下水中,仅少量地下水水样中检出了苯系物,但它们的浓度均低于生活饮用水的要求限值。

摘  要:
Through determination of river water,river sediments,soil profiles along the river,and groundwater,the distribution characteristics of BTEX,which were detected in the water of Cihe River in the piedmont plain of Taihang Mountains,was studied systematically.The results showed that the contaminants in different media are closely related.The soil samples from different depth and distance of the profiles along the river indicated that BTEX are mainly from the river.Because of the attenuation processes(e.g.adsorption to soils),the content of organic contaminants in soils decreases significantly with depth and distance from the river.The data of shallow groundwater samples from the well of different distance from the river showed that the organic contaminants were only detected in a few wells and their concentration can still meet the standards of drinking groundwater.
