关于粗颗粒（PM10-2.5）健康风险的证据有限。在亚洲发展中国家没有对PM10-2.5进行多城市流行病学研究。我们研究了北京、上海和沈阳三个中国城市PM10-2.5与每日死亡率之间的短期关系。PM10-2.5浓度通过从PM10测量值中减去PM2.5来估计。数据分析采用过分散广义线性泊松模型。北京（2007-2008）、上海（2004-2008）和沈阳（2006-2008）的PM10-2.5日均浓度分别为101 μ g/m(3)、50 μ g/m(3)和49 μ g/m(3)。在单一污染物模型中，三个城市的联合分析显示，PM10-2.5与总非意外原因和心肺疾病导致的每日死亡率之间存在显著关联。滞后1天的PM10-2.5浓度每增加10 μ g/m(3)，总死亡率增加0.25% (95% CI: 0.08 ~ 0.42)，心血管死亡率增加0.25% (95% CI: 0.10 ~ 0.40)，呼吸系统死亡率增加0.48% （95% CI: 0.20 ~ 0.76）。然而，在调整PM2.5后，这些关联在统计上不显著。调整PM10-2.5前后，PM2.5与死亡率均显著相关。综上所述，PlAro-z和PlAro-z之间没有统计学上的显著关联。在调整PM2.5后，中国三个城市的s和日死亡率。(C) 2011 Elsevier B.V.版权所有
Evidence concerning the health risks of coarse particles (PM10-2.5) is limited. There have been no multi-city epidemiologic studies of PM10-2.5 in developing Asian countries. We examine the short-term association between PM10-2.5 and daily mortality in three Chinese cities: Beijing, Shanghai, and Shenyang. PM10-2.5 concentrations were estimated by subtracting PM2.5 from PM10 measurements. Data were analyzed using the overdispersed generalized linear Poisson models. The average daily concentrations of PM10-2.5 were 101 mu g/m(3) for Beijing (2007-2008), 50 mu g/m(3) for Shanghai (2004-2008), and 49 mu g/m(3) for Shenyang (2006-2008). In the single-pollutant models, the three-city combined analysis showed significant associations between PM10-2.5 and daily mortality from both total non-accidental causes and from cardiopulmonary diseases. A 10-mu g/m(3) increase in 1-day lagged PM10-2.5 was associated with a 0.25% (95% CI: 0.08 to 0.42) increase in total mortality, 0.25% (95% CI: 0.10 to 0.40) increase in cardiovascular mortality, and 0.48% (95% CI: 0.20 to 0.76) increase in respiratory mortality. However, these associations became statistically insignificant after adjustment for PM2.5. PM2.5 was significantly associated with mortality both before and after adjustment for PM10-2.5. In conclusion, there were no statistically significant associations between PlAro-z.s and daily mortality after adjustment for PM2.5 in the three Chinese cities. (C) 2011 Elsevier B.V.
