摘要
对2002-2003年采集于长江河口区域的水样进行了检测分析.共鉴定出有机污染物9类234种,包括VOCs23种、SVOCs211种;其中属美国列出的129种优先控制污染物的有49种,属我国列出的58种优先控制污染物的有24种,属GB3838—2002控制的有19种.VOCs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0.42和0.17μg/L.SVOCs主要包括多环芳烃类、酯类、单环芳香族类、卤代烃类、酚类和醚类,其质量浓度平均值分别为0.50,1.13,0.41,0.06,0.07和0.16μg/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1.78,0.16~0.37和0.002~0.44倍.
The check measurement to the water from Yangtze estuary area in 2002-2003 was carried out. The qualitative results demonstrate that 234 kinds of organic substances in 9 categories are checked out, including 23 kinds of VOCs and 211 kinds of SVOCs; there are 49 kinds of EPA priority-controlled organic substances, 24 kinds of national priority-controlled organic substances, and 19 kinds of GB3838-2002 controlled organic substances. The quantitative results demonstrate that VOCs mainly embrace halogenated hydrocarbons and mononuclear aromatics whose average mass concentrations are 0.42 and 0.17 μg/L, respectively; SVOCs mainly embrace PAHs, esters, mononuclear aromatics, halogenated hydrocarbons, phenols and ethers whose average mass concentrations are 0.50, 1.13, 0.41, 0.06, 0.07 and 0.16 μg/L, respectively; the pollution of PAHs, esters and mononuclear aromatics whose overruns are 1.78, 0.16 - 0.37 and 0.002 - 0.44, respectively is relatively serious.
