摘要
越来越多的国内外流行病学调查与研究发现，大气颗粒物的暴露与居民不同疾病死亡率的上升存在着显著的相关关系。本文就不同粒径颗粒物与最严重的健康终点——死亡之间关系的流行病学研究，进行较为系统的回顾和评述。指出：大多数研究就可吸入颗粒物（PM10）对死亡终点的影响已进行了较为系统和深入的探讨，目前研究重点向细颗粒物（PM2.5）对健康终点的影响转移。而粗颗粒物（PM10-2.5）以及与PM2.5之间的比较性研究资料还较为有限。超细颗粒物（PM0.1）的暴露及健康影响数据也很有限。但由于其数量浓度的优势，可能会成为未来流行病学研究的重点。
Numerous epidemiological studies have confirmed significant associations between atmospheric particulate matter （PMs） exposure and an increase of cause-specific mortality. This review systematically expounds that atmospheric exposure to size- fractionated PMs is associated with the most severe health endpoint--mortality. It points out that given the extensively studied relationship between PM10 and mortality, researchers are turning their attention to PM2.5. However, there are limited data on the comparison between PM10-2.5 and PM2.5 and on the health effects of PM0.1 exposure. PM0.1 will be an important fraction of future epidemiological studies because of its huge number concentrations.
