摘要
对 2 0 0 3年 11月采自北京通惠河的水和表层沉积物样品中 11种氯苯类有机物进行了分析测定 .结果表明 ,通惠河水中氯苯类有机物的总量范围为 0 . 0 93～ 6 . 6 38μg·L-1,其中DCBs平均占氯苯总量的 88. 8% ;表层沉积物 (干重 )中氯苯的总量范围为 95 . 3～ 182. 7 7ng·g-1,其中DCBs、TCBs、TeCBs、PeCB和HCB分别平均占总量的 15 . 6 %、31. 7%、17. 6 %、2 1 .2 %和13. 9% .与国内外其他区域相比 ,表层沉积物中氯苯类有机物污染较为严重 .水和表层沉积物中的氯苯总量没有显著的相关性 .
Eleven chlorobenzenes (except MCB of a total of 12 in the congener series) in water and surface sediment samples collected from Tonghui River of Beijing China in November,2003 are analyzed. The range of total chlorobenzenes (CBs) was 0.093～6.638 μg·L -1 in water, among which DCBs occupy 88.8%; while 95.3～1 827.7 ng·g -1 in surface sediments, among which DCBs,TCBs,TeCBs,PeCB and HCB occupy 15.6%,31.7%,17.6%,21.2% and 13.9% respectively. Comparison with the results of other research areas, the pollution of CBs in surface sediments is some serious. Besides, there is no significant correlation between total CBs concentrations in water and those in surface sediments.
