黄河河口区域有机污染物的特征分析

Character Analysis of Organic Pollutants in Yellow River Estuary Area

对2004年采集于黄河河口区域的水样进行了检测分析．共鉴定出有机污染物8类192种，包括VOCs33种、SVOCs159种；其中属美国列出的129种优先控制污染物的有62种，属我国列出的58种优先控制污染物的有33种，属GB3838—2002控制的有31种．定量出的VOCs有19种，主要包括卤代烃类和单环芳香族类，其质量浓度平均值分别为0．683和0．609μg／L；定量出的SVOCs有69种，主要包括多环芳烃类、酯类、单环芳香族类、卤代烃类、酚类和农药类，其质量浓度平均值分别为0．458，1．011，0．367，0．121，0．220和0．045μg／L，其中多环芳烃类、酯类和单环芳香族类的污染程度相对较高，分别超标2．857，0．288和0．001—1．543倍．

The check measurement to the water from Yellow River estuary area in 2004 was carried out. The qualitative results demonstrate that 192 kinds of organic substances in 8 categories are checked out, including 33 kinds of VOCs and 159 kinds of SVOCs; there are 62 kinds of EPA prioritycontrolled organic substances, 33 kinds of national priority-controlled organic substances and 31 kinds of GB3838 - 2002 controlled organic substances among them. The quantitative results demonstrate that 19 kinds of VOCs which are worked out mainly embrace halogenated hydrocarbons and mononuclear aromatics whose average mass concentrations are 0.683 and 0.609 μg/L, respectively; 69 kinds of SVOCs which are worked out mainly embrace PAHs, esters, mononuclear aromatics, halogenated hydrocarbons, phenols and pesticides whose average quality concentrations are 0.458, 1.011, 0.367, 0.121, 0.220 and 0.045 μg/L, respectively ; and the pollution of PAHs, esters and mononuclear aromatics whose overruns are 2.857, 0.288 and 0.001 - 1.543, respectively is relatively serious .
