多环芳烃(PAHs)是一类重要的大气污染物,也是细颗粒物(PM2.5)的主要有毒组分.在我国当前强氧化性的大气复合污染条件下,多环芳烃易被大气中多种氧化剂(·OH,O3,Nox等）氧化成毒性更高的硝基、羟基或含氧多环芳烃(NPAHs、OHPAHs、OPAHs),从而显著增强PM2.5的毒性而对人体健康产生危害.
CeO2 has been widely used in soot catalytic oxidation on account of its excellent oxygen storage capacity and rich active oxygen species.Catalytic activities has been improved with CuO incorporating i
随着纳米技术的广泛应用,纳米材料不断地进入到空气、土壤、水体等环境中,当然,评估其环境效应和潜在的风险是当前环境化学研究者关注的热点.大多数人认为,尽管铁是一种在自然界中分布广泛并且没有毒性的物质,但是当其粒径达到纳米级别时,由于尺寸效应,不可避免地会引起其物理化学性质的变化,并且很可能对生物体产生毒性作用.因此,对纳米铁进行相关的毒性效应研究是十分必要的.
