【摘要】：目的探讨华北某重污染城市大气PM_(2.5)与PM_(10)浓度与该市居民神经系统疾病急救人次的关系。方法收集该城市2013年1月1日至2015年12月31日的PM_(2.5)与PM_(10)日均浓度、气温和相对湿度,以及每日神经系统疾病急救人数,采用广义相加时间序列模型,控制长期趋势、气象因素、"星期几效应"和节假日效应等混杂因素后,分析大气PM_(2.5)、PM_(10)浓度与每日神经系统疾病急救人次的关系。结果大气中PM_(2.5)(lag 03)与PM_(10)(lag 04)浓度每升高10μg/m~3,该市居民因神经系统疾病急救的人次分别增加0.75%(95%CI 0.34%~1.17%)和0.35%(95%CI 0.05%~0.66%)。结论大气颗粒物污染尤其是PM_(2.5)浓度的升高可能增加了居民神经系统疾病的风险。
[Abstract]:Objective to investigate the relationship between the concentrations of PM_ _ (2.5) and PM_ _ (10) in the atmosphere of a heavily polluted city in North China. Methods the daily mean concentrations of PM_ (2.5) and PM_ (10), air temperature and relative humidity, and the number of daily emergency patients with neurological diseases were collected from January 1, 2013 to December 31, 2015 in the city, and the generalized additive time series model was used. After controlling the long-term trend, meteorological factors, "week day effect" and holiday effect, the relationship between the concentration of atmospheric PM_ _ (2.5) and PM_ _ (10) and daily emergency number of nervous system diseases was analyzed. Results the concentrations of PM_ (2.5) (lag 03) and PM_ (10) (lag 04) in the atmosphere increased by 10 渭 g / m ~ (4), The number of emergency patients with neurological diseases increased by 0.75% (95%CI 0.34 1.17%) and 0.35% (95%CI 0.05 0.66%) respectively. Conclusion Atmospheric particulate pollution, especially the increase of PM_ _ (2. 5) concentration, may increase the risk of nervous system diseases in residents.
