| 1 | Organochlorine compounds and polycyclic aromatic hydrocarbons in surface sediment from Baiyangdian Lake,North China:Concentrations,sources profiles and potential risk显示文摘Organochlorine pesticides(OCPs),polychlorinated biphenyls(PCBs),and polycyclic aromatic hydrocarbons(PAHs) were determined in nineteen surface sediment samples collected from Baiyangdian Lake and its inflowing river(Fuhe River) in North China.Total concentrations of OCPs,PCBs and PAHs in sediments ranged from 5.4 to 707.6 ng/g,2.3 to 197.8 ng/g,and 101.3 to 6360.5 ng/g,respectively.The levels of contaminants in Fuhe River were significantly higher than those in Baiyandian Lake.For hexachlorocyclohexane(HCHs) and dichlorodiphenytrichloroethanes(DDTs),α-HCH and p,p-DDT were predominant isomers;while for PCBs,PCB 28/31,PCB 40/103,PCB 60,PCB 101,and PCB 118 were predominant congeners.Possible sources derived from historical usage for OCPs and incomplete combustion fuel,wood,and coal and exhaustion of boats or cars for PAHs.Risk assessment of sediment indicated that sediments in Fuhe River were likely to pose potential biological adverse impact. | Guocheng Hu Xiaojun Luo Fengchao Li Jiayin Dai Jianyang Guo Shejun Chen Cao Hong Bixian Mai Muqi Xu | 2010 | Journal of Environmental Sciences2010，22，2： | 42 |
| 2 | Distribution of polybrominated diphenyl ethers and decabromodiphenylethane in surface sediments from Fuhe River and Baiyangdian Lake,North China显示文摘Nineteen surface sediment samples collected from Baiyangdian Lake and its inflowing river (Fuhe River) in North China were analyzed for polybrominated diphenyl ethers (PBDEs) and decabromodiphenylethane (DBDPE).The concentrations of PBDEs and DBDPE in sediments ranged from 5.5 to 300.7 ng/g dry weight (dw) and 1.1 to 68.2 ng/g dw,respectively.Their levels in sediments in Fuhe River were significantly higher than those in Baiyandian Lake.Compared to data from other regions,the PBDE levels in surface sediments from Baiyangdian Lake and Fuhe River were in the medium to lower range.Among the PBDE congeners,BDE209 was predominant,with contributions to the total PBDEs ranging from 79.4% to 97.3% in sediment samples.For the lowly brominated congeners (tri-to hepta-BDE),BDE47 and BDE99 were the most abundant,which contributed 52.1% and 44.1% to the sum of tri-to hepta-BDEs in the sediments from Baiyangdian Lake and Fuhe River,respectively.The compositional patterns of PBDEs in Baiyangdian Lake sediments indicated that technical deca-BDE mixture was the major pollutant sources with a minor contribution of penta-BDE mixture.The present study suggested that the importance of Fuhe River as a possibly potential sources of PBDEs contamination in Baiyangdian Lake. | Guocheng Hu Zhencheng Xu Jiayin Dai Bixian Mai Hong Cao Jianshe Wang Zhimin Shi Muqi Xu | 2010 | Journal of Environmental Sciences2010，22，12： | 18 |
| 3 | Characteristics of microfauna and their relationships with the performance of an activated sludge plant in China显示文摘微动物志组织的出现和许多与在中国的 Baoding Lugang 污水处理工厂的物理化学、运作的参数相比。属于并且爬行纤毛虫类是纤毛虫类的主导的组。爬行纤毛虫类和留有遗嘱的阿米巴与自河 BOD5 (生物化学的氧需求) 显示出一个强壮的协会。因此,自从他们的数字减少了,当这个过程生产了差的优秀自河,这二个组是可能的是有用简历指示物。留有遗嘱的阿米巴也有重要负相关与自河 TN (总氮) , NH4+-N, SS (推迟的固体) 和 SVI (污泥容量的索引) ,它意味着这组纤毛虫类可以是活性污泥系统的好性能的指示物。食肉的纤毛虫类和 flagellates 与 SVI 有重要正相关,建议这二个组可以是污泥的坏解决条件的指示物。因为微动物志种类的鉴定困难、费时间,我们用微动物志建议功能的组评估活性污泥系统的性能。 | ZHOU Kexin XU Muqi LIU Biao CAO Hong | 2008 | Journal of Environmental Sciences2008，20，4： | 5 |
