摘要: 研究了纳米材料(多壁碳纳米管和纳米氧化锌)泄漏进入水环境后吸附多环芳烃(菲)对水生生态系统可能造成的影响及其影响机制,以便能及早采取相应的风险管理措施.实验结果表明,多壁碳纳米管(MWCNTs)显著降低了菲(Phe)在鲫鱼肌肉和肝脏中的富集,但增加了其在鱼脑中的富集量;C-Phe组菲在眼部、胚胎和生殖腺中含量均高于ZnO-Phe组.MWCNTs、nZnO与菲均诱导鲫鱼脑部和肝脏组织中自由基的生成.

Abstract: In this study, the impacts of nanomaterials (including multi-walled carbon nanotubes and nanosized ZnO) in the presence of phenanthrene were studied. The reaction mechanisms were also investigated and it was designed to address the potential environmental impacts of manufactured nanomaterials. The results show that the concentrations of phenanthrene in the brain of Carassius auratus increased while those in the liver decreased significantly in the presence of MWCNTs. With the coexisting nZnO, the concentration of phenanthrene in the gonad embryo and eye of the fish were higher than the one with the coexisting MWCNTs. In the brain and liver of the fish, free radicals induced by MWCNTs, nZnO and phenanthrene.
