【摘要】：目的:讨论灰霾天气和非灰霾天气中存在的主要大气污染物(PM10、SO_2、NO_2、PM2.5、CO、O3)的分布特征,以及其对人群呼吸系统急性健康效应的影响。方法:采用广义相加模型的统计方法,分析灰霾天气中主要大气污染物与呼吸系统疾病每日就诊人数变化的关系及呼吸系统疾病日死亡人数变化的关系。结果:2013~2015年,PM10、SO_2、NO_2、PM2.5、CO、O3(8 h)等6种主要大气污染物中,除了PM2.5年日均浓度水平略高于《环境空气质量标准》(GB3095-2012)规定的浓度限值外,其余5种均低于《环境空气质量标准》(GB3095-2012);霾天气时,PM10、SO_2、NO_2、PM2.5和CO的浓度与非霾天气时的差异均有统计学意义(P0.01);PM10、SO_2、NO_2、PM2.5、O3浓度的升高均会在不同观察日时,导致我区医疗机构呼吸系统日门急诊量不同程度地增加;NO_2、PM2.5、CO、O3(8 h)浓度的升高,会导致我区居民呼吸系统疾病死亡不同程度地增加。结论:霾天气时,PM10、SO_2、NO_2、PM2.5和CO的浓度大于非灰霾天,灰霾天对人群呼吸系统急性健康效应的影响大于非灰霾天。
[Abstract]:Objective: to discuss the distribution characteristics of PM10 / so _ 2N _ (2) O _ (2) O _ (2) O _ (3) in haze and non-haze weather and its effect on the acute health of respiratory system. Methods: the statistical method of generalized additive model was used to analyze the relationship between the main air pollutants in haze and the daily number of patients with respiratory diseases and the daily mortality of respiratory diseases. Results among the six major atmospheric pollutants, the annual average concentration level of PM2.5 was slightly higher than the concentration limit set by GB3095-2012). The other five species are lower than the Ambient Air quality Standards (GB3095-2012C), and the concentrations of PM10 / so _ 2O _ 2O _ 2C _ (2.5) and CO in haze weather are significantly different from those in non-haze weather. The increase in the concentration of PM _ (10) O _ (10) so _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ 3 will be observed on different observation days. As a result, the daily emergency volume of respiratory system in our region increased the concentration of NO2 / PM2.5 / COO _ 3 (8 h), which will lead to the increase of death rate of respiratory system diseases in different degree. Conclusion: in haze weather, the concentrations of PM10 / so _ 2C _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (2) O _ (
