| 摘 要： | 地下水是滹沱河冲积平原主要工农业及生活用水水源,地下水污染程度直接影响到区内居民的健康状况。为阐明人类活动影响下浅层地下水有机污染状况,以滹沱河冲积平原为重点研究区,采集了大量地下水样品进行测试分析。结果表明:区内浅层地下水已经受到有机污染威胁,主要检出有机组分为卤代烃类和氯代苯类,其中三氯甲烷检出率高达14.02%;有机物超标样品较少,但是超标浓度较高,主要超标组分为四氯化碳。利用EPI Suite软件计算可知高检出组分GUS值均较高,有较高的一致性。由于有机物的高毒理性,研究区内有机污染已经不容忽视。

| Abstract: | Groundwater is the source of main agricultural,industrial and domestic water in the alluvial plain of Hutuo River.The pollution degree of groundwater directly affects habitants’ state of health in the area.In order to explain the condition of shallow groundwater organic pollution under the influence of human activities,the alluvial plain of Hutuo River was selected as the main study area,and then by a large amount of groundwater sampling,analysis and test,we analyzed the characteristics of shallow groundwater organic pollution.The results showed that shallow groundwater has been under threat of organic pollution in the area,the main detected organic components are halogenated hydrocarbons,poly-aromatics and chlorobenzenes,among which the detection rate of trichloromethane amounts to 14.02%;Over-standard organics samples are sparse,but the over-standard concentrations are high,the main over-standard component is tetrachloromethane.Because of the high toxicity of organics,organic pollution has become unable to be neglected in the study area. |
