摘　　要：近年来,纳米材料在环境领域的使用越来越广泛。纳米金属氧化物在土壤和水体环境修复领域进行应用时,不可避免地会增加其在环境中的累积及其与人们的直接接触,这会对环境安全、生物生命安全造成不可忽视的危害。文章围绕一些有较高可能被泄露而累积在环境中的纳米材料污染,如纳米CuO、纳米ZnO、纳米Fe_(3)O_(4)等进行相关资料收集,对现有的关于纳米金属氧化物对藻类的毒性效应的试验研究结果进行总结,同时也整理了目前学界普遍认可的一些纳米金属氧化物对藻类的致毒机理。另外还对未来的研究方向作出了展望,如致毒机理中具体过程尚需进一步研究等。In recent years,nanomaterials have been used more and more widely in environmental field.When nano metal oxides are applied in water treatment and soil remediation,they will inevitably accumulate in the environment and their direct contact with people will also be increased,which may do harm to environment and creatures.This paper collect researches about the toxicity of the nanomaterials,such as nano CuO,nano ZnO,nano Fe_(3)O_(4),which may be leaked into environment and accumulate in the environment.In this paper,the recent materials on the toxic effects of nanomaterials on algae are summarized at first.Then,the toxic mechanisms of nanomaterials on algae,which are approved by many different researches,are systematically discussed.Finally,the article presents a prospect of some future research directions,such as the specific process of toxic mechanisms need further study.
