摘要
目的探讨湖北省宜昌市大气颗粒物对急救人次的急性影响。方法收集2014年1月—2017年12月宜昌市的日急救人次、细颗粒物(PM2.5)和可吸入颗粒物(PM10)日均浓度以及气象条件等资料,采用广义相加模型分别分析PM2.5、PM10与非创伤急诊人次数、呼吸系统和循环系统急诊人次数的暴露–反应关系。结果宜昌市2014—2017年PM2.5和PM10日均浓度平均为(72.2±50.7)和(107.6±60.9)μg/m3,非创伤急救人次数、呼吸系统急救人次数和循环系统急救人次数的日平均值分别为(33.3±8.6)、(2.6±2.2)和(5.1±3.4)人次;相关分析结果显示,非创伤急救人次数、呼吸系统急救人次数和循环系统急救人次数与PM2.5和PM10暴露均呈正相关(均P<0.05);当PM2.5日均浓度每升高10μg/m3,当天日均非创伤急救人次数、呼吸系统急救人次数和循环系统急救人次数分别升高0.41%(95%CI=0.10%~0.72%)、1.63%(95%CI=0.62%~2.64%)和0.93%(95%CI=0.17%~1.69%);当PM10日均浓度每升高10μg/m3,当天日均呼吸系统急救人次数和循环系统急救人次数分别升高1.30%(95%CI=0.50%~2.11%)和0.73%(95%CI=0.13%~1.34%)。结论大气颗粒物PM2.5和PM10浓度升高可能导致非创伤急救人次数、呼吸系统急救人次数和循环系统急救人次数明显增加。
Objective To explore acute effect of ambient air particulate matter on hospital emergency room visits in Yichang city,Hubei province.Methods We collected daily data on emergency services,mean concentration of fine particulate matter(particulate matter less than 2.5μm in aerodynamic diameter,PM2.5)and inhalable particulate matter(particulate matter less than 10μm in aerodynamic diameter,PM10),and meteorological conditions in Yichang city from January 2014 through December 2017.Generalized additive model(GAM)was used to analyze associations between PM2.5,PM10 and the numbers of non-traumatic,respiratory and cardiovascular emergency room visits.Results During the 4-year period in the city,the average daily concentration of PM2.5 and PM10 were 72.2±50.7μg/m3 and 107.6±60.9μg/m3;the mean daily numbers of non-traumatic,respiratory,and cardiovascular emergency room visits were 33.3±8.6,2.6±2.2,and5.1±3.4,respectively.There were significantly positive correlations between daily concentration of PM2.5,PM10 and the number of non-traumatic,respiratory and cardiovascular emergency room visits(P<0.05 for all).The results of GAM model analysis demonstrated that a 10μg/m3 increase in average daily PM2.5 concentration was related to the increases of 0.41%(95%confidence interval[95%CI]:0.10%–0.72%),1.63%(95%CI:0.62%–2.64%),and 0.93%(95%CI:0.17%–1.69%)in the numbers of non-traumatic,respiratory,and cardiovascular emergency room visits in the same day and for every 10μg/m3 increase in in average daily PM10,the number of respiratory and cardiovascular emergency room visits in the same day increased by 1.30%(95%CI:0.50%–2.11%)and 0.73%(95%CI:0.13%–1.34%),respectively.Conclusion Increased daily concentration of PM2.5 and PM10 may lead to a significant increase in the number of non-traumatic,respiratory and cardiovascular emergency room visits.
