【摘要】：目的探討華北某重污染城市大氣PM_(2.5)與PM_(10)濃度與該市居民神經(jīng)系統(tǒng)疾病急救人次的關(guān)系。方法收集該城市2013年1月1日至2015年12月31日的PM_(2.5)與PM_(10)日均濃度、氣溫和相對(duì)濕度,以及每日神經(jīng)系統(tǒng)疾病急救人數(shù),采用廣義相加時(shí)間序列模型,控制長(zhǎng)期趨勢(shì)、氣象因素、"星期幾效應(yīng)"和節(jié)假日效應(yīng)等混雜因素后,分析大氣PM_(2.5)、PM_(10)濃度與每日神經(jīng)系統(tǒng)疾病急救人次的關(guān)系。結(jié)果大氣中PM_(2.5)(lag 03)與PM_(10)(lag 04)濃度每升高10μg/m~3,該市居民因神經(jīng)系統(tǒng)疾病急救的人次分別增加0.75%(95%CI 0.34%~1.17%)和0.35%(95%CI 0.05%~0.66%)。結(jié)論大氣顆粒物污染尤其是PM_(2.5)濃度的升高可能增加了居民神經(jīng)系統(tǒng)疾病的風(fēng)險(xiǎn)。
[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.
