华北平原地下水有机污染特征初步分析
Preliminary analysis on the organic contamination of groundwater in the North China Plain
摘要
Abstract
The groundwater quality is highly influenced by input of contaminants from various sources. In order to acquire the current status of groundwater quality in the North China Palin (NPC), 245 water samples were collected according to the relating reqirements and standards. The samples were analysed by qualified laboratories. The investigation results showed that there were 32 organic contaminants detected in groundwater in the NPC. Among these compounds, the detection frequencies (ratio of number of samples with organic compound(s) detected to the total number of samples) of chloroform, toluene, tetrachloroethylene, benzo[a]pyrene xylene, chlorobenzene, benzene, and 1, 2-dichlorobenzene are higher than 4.5%. According to the standards of groundwater quality (China Geological Survey, 2007), the concentrations of carbon tetrachloride, benzo[a]pyrene, and volatile phenols some water samples (<2.5% of the total) were higher that that for class III, which corresponds to the drinking water standards. It should be noted that there were organic contaminants detected in some deep groundwater samples. This suggests that further monitoring work should be carried out for these sites. Normally, the higher detection frequency of organic contaminants corresponds to reagion with intensive human activities, especially in the pediment reagion, due to its high permeability of the geological media. The results preliminarily indicated that there is a correlationship between the organic contaminantion and the increase of the water hardness. Due to the high temporal and spatial heterogeneity of groundwater organic contamination, it is suggested that further monitoring work should be carried out for these sites where organic contaminants were detected.关键词
