发布时间：2018-11-05 08:11
【摘要】：目的探讨银川市大气颗粒物污染水平及其对居民循环系统疾病死亡的暴露-反应关系。方法通过收集银川市2013—2015年空气质量监测数据、气象监测数据和居民死亡监测资料,采用广义相加模型,分析银川市大气颗粒物物对与居民循环系统疾病死亡的暴露-反应关系。结果大气PM_(10)和PM_(2.5)年均浓度均超过GB 3095—2012《环境空气质量标准》二级标准。大气PM_(10)和PM_(2.5)浓度每升高10μg/m~3对人群循环系统疾病死亡的超额危险度分别为0.56%(95%CI:0.15%~0.97%),1.33%(95%CI:0.46%~2.21%);大气PM_(10)和PM_(2.5)浓度对小于65岁组的循环系统疾病死亡的影响无统计学意义(P0.05),对65岁以上年龄组人群循环系统疾病死亡的超额危险度分别在滞后7、5 d时达到最大效应,分别为1.24%(95%CI:0.21%~2.28%)和0.57%(95%CI:0.08%~1.06%);大气PM_(10)、PM_(2.5)浓度对女性循环系统疾病死亡的超额危险度高于男性。结论研究期间银川市大气颗粒物浓度较高,且对人群循环系统疾病死亡存在一定的暴露-反应关系。
[Abstract]:Objective to investigate the level of atmospheric particulate pollution and the relationship between exposure and response to circulatory diseases in Yinchuan. Methods by collecting air quality monitoring data, meteorological monitoring data and resident death monitoring data from 2013 to 2015 in Yinchuan City, a generalized additive model was used. The relationship between exposure and death of atmospheric particulates and circulatory diseases in Yinchuan was analyzed. Results the average annual concentrations of PM_ (10) and PM_ (2.5) in the atmosphere exceeded the second grade of GB 3095-2012. For each 10 渭 g/m~3 increase in atmospheric PM_ _ (10) and PM_ _ (2.5) concentrations, the excess risk of death from circulatory diseases in the population was 0.56% (95 CI: 0.15 0.97%). 1.33% (95% CI: 0.46%); The effects of atmospheric PM_ _ (10) and PM_ _ (2.5) concentrations on the mortality of circulatory diseases in patients younger than 65 years old were not statistically significant (P0.05). The excess risk of circulatory disease death in the age group over 65 years old reached the maximum effect at the time of delay of 7d or 5d, respectively. It was 1.24% (95% CI: 0.21 and 2.28%) and 0.57% (95% CI: 0.08% 1.06%); Atmospheric PM_ (10) and PM_ (2. 5) concentrations had higher excess risk of circulatory disease death in women than in men. Conclusion during the study period, the concentration of atmospheric particulate matter in Yinchuan City was high, and there was a certain relationship between exposure and response to the death of circulatory diseases in the population.
