To investigate the possible relationship between airborne particulate matter and mortality, we developed regression models of daily mortality counts using meteorological covariates and measures of outdoor PM10. Our analyses included data from Cook County, Illinois, and Salt Lake County, Utah. We found no evidence that particulate matter < or = 10 microns (PM10) contributes to excess mortality in Salt Lake County, Utah. In Cook County, Illinois, we found evidence of a positive PM10 effect in spring and autumn, but not in winter and summer. We conclude that the reported effects of particulates on mortality are unconfirmed.
为了研究空气中颗粒物与死亡率之间的可能关系,我们利用气象协变量和室外PM10测量值建立了每日死亡人数的回归模型。我们的分析包括来自伊利诺伊州库克县和犹他州盐湖县的数据。我们没有发现证据表明直径小于或等于10微米的颗粒物(PM10)会导致犹他州盐湖县的超额死亡率。在伊利诺伊州库克县,我们发现春季和秋季存在PM10的正向影响证据,但冬季和夏季没有。我们得出结论,关于颗粒物对死亡率影响的报道尚未得到证实。
