南京市大气污染物与居民心脑血管疾病死亡的相关性

Correlation between air pollutants and cardio-cerebrovascular mortality in Nanjing

  • 摘要: 目的 探讨南京市大气污染物与居民心脑血管疾病死亡的相关性。

    方法 收集南京市2013年1月1日-2016年12月31日大气污染物粗颗粒物(PM10)、细颗粒物(PM2.5)、二氧化氮(NO2)、一氧化碳(CO)、二氧化硫(SO2)、臭氧(O3)的平均质量浓度、气象数据(包括气压、温度、相对湿度的日平均值)和居民每日心脑血管疾病死亡人数,采用时间序列分析大气PM2.5质量浓度与居民每日心脑血管疾病死亡率的关系。

    结果 大气污染物PM10、PM2.5、NO2、CO、SO2、O3质量浓度分别为106.1、62.1、45.6、1.0、25.1、86.0 μg/m3。其中PM10、PM2.5、NO2平均质量浓度高于《环境空气质量标准》(GB 3095-2012)二级标准。在单污染物模型中,大气PM2.5日均质量浓度每增加10μg/m3,心脑血管疾病死亡风险增加0.293%(95% CI:0.016%~0.569%)。在双污染物模型中,当引入其他污染物后,大气PM2.5对居民心脑血管疾病死亡率的影响消失(P>0.05)。

    结论 大气PM2.5污染可能增加南京市居民心脑血管疾病的死亡风险。

     

    Abstract: Objective To assess the correlation between air pollutants and cardio-cerebrovascular mortality (CCM) in Nanjing.

    Methods Daily average concentrations of crude particles (PM10), fine particles (PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone (O3), meteorological factors (including air pressure, temperature, and relative humidity), and daily cardiovascular and cerebrovascular deaths during 2013-2016 in Nanjing were collected to analyze the relationship between PM2.5 concentration and CCM by time-series analysis.

    Results The average concentrations of PM10, PM2.5, NO2, CO, SO2, and O3 were 106.1, 62.1, 45.6, 1.0, 25.1, and 86.0 μg/m3, respectively.The results of PM10, PM2.5, and NO2 exceeded the national ClassⅡ standard stipulated by Ambient air quality standard (GB 3095-2012).In single pollutant model, an increase of 10 μg/m3 in PM2.5 concentration raised CCM risk by 0.293% (95% CI:0.016%-0.569%).As for two-pollutant model, when entering other pollutants, the association of PM2.5 with CCM disappeared (P>0.05).

    Conclusion PM2.5 may increase the CCM risk in Nanjing.
