- 摘要:对白洋淀地区不同类型纸厂排水口底泥及保定市排污渠底泥进行了GC/ECD分析,可萃取有机氯(EOCl)含量测定,检出了多氯联苯和有机氯农药。用截止分子量为1000道尔顿的透析袋方法对相应地区的水体进行了检测,发现水体中可检出含氯农药六六六,但多氯联苯等由于水中存在浓度低未能检出,同样样品的GC/MS/COM结果表明,水体中主要存在的亲脂性有机污染物为:蒽酮、蒽二酮、苯胺、氯代烃、邻苯二甲酸酯类和苯系物。
- Abstract:PCBs and chorinated pesticides are found in the sediment samples collected from diffe-rent sort of paper mill waste water discharge points and the city Baoding industrial wastewater effluents joint point.The concentration of PCBs is 510.9,112.4 ng per gram drysediment for effluents joint point and a paper mill dischare point,respectively.Extractable organically bound chlorine(EOCI)in the sediment samples was also deter-mined by solvent extraction and neutron activation technique,The volue of EOCI is6.7,13.3,3.7,and 43.0μg per gram dry sediment for effluents joint point and paper mill dis-charge points A,B,D, respectively.The concentration of identified compounds shch asPCBs and chlorinated pesticides constitutes only a minor fraction of the EOCI,less than onepercent for samples A and D,about 3-9per cent for sampples B and C.Considering paper mill B used to take used paper as raw material to make paper, it isreasonable to think of that PCBs originally in the used paper pant will turn to the dischargewater through the process. It is possible that PCBs could even more widly spread by the ef-fluent and the resuspended sediment.Cut off 1000 MW dialysis tubing was sued to collect lipophilic organics from water.BHC was found in all water samples by GC/ECO analysis,The results of GC/MS/COManalysis show that main organics in water are anthrone,anthracenedione,naphthalene,N-phenyl-naphthalenamine, phthalates, chlorohydrocarbons,and benzenhydrocarbons.Summarilly, PCBs pollution takes priority to other organic pollution in the area,moredetailed study on PCBs should be conducted.
