Impact of Tubificids (Tubifex) on the release of sediment-associated DE 83
本套完整资料共包括开题报告，毕业论文，毕业答辩PPT稿，英文文献原文，英文文献翻译，学年论文共6个部分
摘 要
本文主要通过模拟实验来研究颤蚓对沉积物中多溴联苯醚释放的影响，即在养殖锦鲤鱼的鱼缸中铺设底泥，并在一组鱼缸的底泥中投入颤蚓，另一组鱼缸的底泥中不投入颤蚓，通过定期测试进鲤鱼体内多溴联苯醚含量来分析讨论问题。并且在实验过程中对各注入渤海的河流沉积物中多溴联苯醚进行简单调查研究，对其污染水平和分布特点进行初步探索。本实验结果如下：
（1）有颤蚓组别锦鲤鱼体内的多溴联苯醚含量明显高于无颤蚓组别锦鲤鱼体内的多溴联苯醚含量，说明颤蚓会使底泥沉积物中的多溴联苯醚释放出来，并在锦鲫鱼体内富集。
（2）在实验的20天时间里，锦鲫鱼体内ΣPBDEs增长的净含量为606.60ng/g (脂肪)。含量最高的多溴联苯醚同系物为BDE-47，增长的净含量为334..99ng/g (脂肪)，占ΣPBDEs比例近似55.22%。其次是BDE-154、-100，增长净含量分别为72.73,40.94ng/g(脂肪)。
（3）低溴联苯醚BDE-28、-47、-100、-154易在锦鲤鱼体内富集，高溴联苯醚不易富集或易在锦鲤鱼体内转化为低溴联苯醚。
（4）大沽排污河是本次调查研究的各入海河流沉积物中多溴联苯醚含量最高的河流，独流减河和北排河沉积物中的多溴联苯醚的含量次之，但污染水平并没有超过我国其他河流。
（5）永定新河口、独流减河万家码头大桥、唐津高速桥下、永和大桥、子牙新河、青静黄挡潮闸等处沉积物中的PBDEs含量都较低，与日本报道的海洋沉积物低水平相当。

ABSTRACT
In this paper,mainly through simulation experiments to study the impact of tubificids on the realese of sediments-associated the polybrominated diphenyl ethers(PBDEs).That's brocade carps in a aquarium having the sediment and the sediment in one group of aquarium being input tubificids, another group of aquarium do not put tubificids in sediment, through regular testing the contents of PBDEs in the brocade carps to discuss the questions of PBDEs.And during the experiments course ,we also observed the contents of PBDEs in the sediment of rivers into the Bohai Sea,and its pollution levels and distribution were also investigated.
(1).The group that the sediment with tubificids brocade carps' PBDEs contents obvious higher than no tubificids group, that's explain the tubificids may use the PBDEs in the sediment to release out and enrich in the brocade carps.
(2).The increasing net contents of ΣPBDEs in brocade carps is 606.60 ng/g (lipid)within 20 days time of experiment.The highest contents of the congeners is BDE-47and the increasing net contents is 334.99 ng/g (lipid), proportion in ΣPBDEs is nearly 55.22%. The secondary is BDE-154, -100, being 72.73 , 40.94 ng/g (lipid) respectively.
(3).Low bromine biphenyl ether BDE-28, -47, -100, -154 are easy to enrich in brocade carps, but high bromine biphenyl ethers are difficult to concentration or they are easy to transformate to low bromine biphenyl ether in the brocade carps.
(4).The contents of PBDEs in the sediment of the Da Gu drain contamination river is the highest of all the rivers' of we investegate ,secondary is Du Liu Jian river and Bei Pai river', but contaminate level do not exceed our country's other rivers.
(5).The content of PBDEs in the sediments of Yong Ding Xin river, Du Liu Jan Wan Jia Ma Tou bridge, high-speed bridge of Tangjin, Yong He bridge, Zi Ya Xin river, Qing Jing Hang Dang Chao Fa PBDEs is low, comparatively around to the level that Japan reports.
