PM_(2.5)对成人及胎儿心血管系统不良效应

Adverse effect of PM_(2.5) on cardiovascular system in adults and fetuses

近年中国大气污染严重,其健康影响受到人们高度关注。大气颗粒物污染中细颗粒物(PM_(2.5))的健康危害最大。大量证据表明,大气PM_(2.5)与心血管疾病有密切关系,并且PM_(2.5)对成年期和胎儿期这两个不同时期心血管系统的不良效应存在统计学差异。本文分别针对PM_(2.5)对成人心血管系统及胎儿心血管发育不良效应的研究进展作一回顾。

Air pollution has been serious in China in recent years and its effect on human health is highly concerned by the public. Among the particulate pollutants, particulate matter 〈 2. 5 microns in aerodynamic diameter （ PM2.5 ） imposes the most adverse effect on human health. Substantial evidences suggest that PM2.5 pollution relates closely to the incidence of cardiovascular diseases and the adverse effects of PM2.5 are significantly different among the adults and fetuses. The latest research progress on adverse effects of PM2. 5 on adult cardiovascular system and the development of fetal cardiovascular system were reviewed in this article.
