摘要(Abstract)：

近些年,我国大气颗粒物所带来的健康问题越发突出,由此产生的环境疾病日益引起人们的广泛关注。大量的流行病学和毒理学研究发现,大气颗粒物能引起呼吸系统、心血管系统、神经系统、免疫系统等的损伤,造成新生儿出生缺陷,增加罹患癌症的风险,且与人群发病率和死亡率上升有关。但是由于大气颗粒物物化属性比较复杂,一种或几种损伤机制并不能完全解释其与致病效应的关系,因此具体的损伤机制目前还没有统一的说法,大气颗粒物物理化学属性与致病效应的关系仍在探索当中。本文从大气颗粒物的粒径、浓度、比表面积、来源、成分等基本属性入手,剖析其基本特点和可能影响健康的原因,探讨大气颗粒物通过氧化损伤途径诱导致病效应,并结合当前大气颗粒物健康影响研究现状提出在未来研究中应注重的相关内容。

关键词(KeyWords)： 颗粒物;环境疾病;损伤机制;氧化损伤;ROS;PM2.5
