纳米银在水环境中的环境行为和毒性效应研究进展
Review of Environmental Behavior and Toxicity of Silver Nanoparticles in the Aquatic Environment
-
摘要: 纳米材料的环境行为和生态效应是目前国内外研究的热点,其中纳米银颗粒(AgNPs)是使用量最高的纳米材料。本文主要总结了AgNPs在水环境中的赋存、AgNPs的环境行为、AgNPs对不同种类微生物的毒性效应以及影响AgNPs毒性效应的因素,最后对AgNPs在河口区的研究进行了展望。Abstract: The environmental behaviour and ecological impact of nano-materialshave attracted increasing attention in recent years. Silver nanoparticles (AgNPs) are the most frequently used nano-materials. This review summarizes research progress on the behavior and toxicity of AgNPs in the aquatic environment. Occurrence, environmental behavior, toxicity to various microorganisms, and the factors influencing toxicity of AgNPs are summarized. Finally, perspectives for future research regarding AgNPs in estuarine environment are discussed.
