大气中不同粒径颗粒物诱导人羊膜FL细胞UDS的研究

Unscheduled DNA Synthesis Induced in Human Amnion Cell FL by Variously-sized Atmospheric Particles

本研究以诱导人羊膜细胞ＵＤＳ为指标，对太原市大气不同粒径的颗粒物提取液进行了致突变性检验，结果表明，不同粒径颗粒物的提取液均可产生一定的遗传毒性，尤以３．３μｍ以下的颗粒物的遗传毒性较强。

Using the unscheduled DNA Synthesis (UDS) in human amnion cell FL, we observed the mutagenicity of variously-sized atmospheric particles.The result demonstrated that. the extract of variously-sized atmospheric particles have genetic toxicity, especially the particles less than 3.3μm having higher genetic toxicity.
