中文摘要：
研究了黄河中下游小浪底-花园口-高村河段表层水、悬浮颗粒物和沉积物中10种硝基苯类有机污染物的含量．结果表明。水样中检测到8种硝基苯类有机污染物，其中盂州—干渠中硝基苯浓度最高，为8．4268μg·L^-1，但都没有超过国家标准（GB3838-2002）．伊洛河的悬浮颗粒物中硝基苯类有机物的总浓度达164．382μg·kg^-1．洛阳石化沉积物中硝基苯类有机物的总浓度最高，为14．718μg·kg^-1．在三相（表层水、悬浮颗粒物和沉积物）中，硝基苯的含量最高．硝基苯类有机物在水、沉积物和悬浮颗粒物中的大体分布趋势为悬浮颗粒物〉沉积物〉表层水，沉积物中的污染物有再次释放到水体中的趋势．
英文摘要：
The work presents preliminary study on the organic contaminants of ten nitrobenzenes in the water, suspended solids and sediment samples collected from eleven sampling sites in the middle and downstream of the Yellow River （from Xiaolangdi to Gaocun reach）. The results indicated that eight kinds of nitrobenzenes were detected in water samples except 4-nitrotulene and 2,6-dinitrotulene. The high concentration of Nitrobenzene in the water from Mengzhouyiganqu site was detected, it was up to 8.426 8μg· L^-1, but they were all below the national standard （GB3838-2002）. The total concentration of Nitrobenszenes in the suspended solids of Yiluo river is the highest, it is up to 164. 382μg·kg^-1, The high concentration of nitrobenzenes in the sediment from Luoyangshihua site is detected. It is up to 14.718μg·kg^-1. The concentration of nitrobenzene in three phases is highest. The distribution of nitrobenzens in three phases showed following order： suspended solids 〉 sediment 3〉 surface water. From the results, we can also conclude that the contaminations in sediment samples have a trend to release into water again.
