OBJECTIVE
To access the relationship between ambient particulate matter( PM_(2. 5)and PM_(10)) concentration and daily emergency ambulance dispatches due to neurological diseases in one city of the North China.
METHODS
Semi-parametric generalized additive model was used to analyze the relationship between particulate matter( PM_(2. 5)and PM_(10)) concentration and daily emergency ambulance dispatches due to neurological diseases from January 1, 2013 to December 31, 2015 after adjustment for time trends, weather conditions and "days of the week".
RESULTS
An 10 μg/m~3 increase in the lag 03 day concentration of PM_(2. 5)corresponded to increase of 0. 75%( 95% CI0. 34%-1. 17%) in daily emergency ambulance dispatches due to neurological diseases, and an 0. 35%( 95% CI 0. 05%-0. 66%) increase correspondence for PM_(10) in the lag04.
CONCLUSION
Outdoor particulate matter( PM_(2. 5)and PM_(10)) concentration is significantly associated with increased risk of emergency ambulance dispatches due to neurological diseases in the North China.
目的
探讨中国北方某城市环境颗粒物（PM₂.₅和PM₁₀）浓度与因神经系统疾病导致的每日急救车出车次数之间的关系。
方法
采用半参数广义相加模型，在对时间趋势、天气状况和“星期几”进行校正后，分析2013年1月1日至2015年12月31日期间颗粒物（PM₂.₅和PM₁₀）浓度与因神经系统疾病导致的每日急救车出车次数之间的关系。
结果
PM₂.₅滞后03天浓度每增加10 μg/m³，因神经系统疾病导致的每日急救车出车次数增加0.75%（95%CI：0.34% - 1.17%）；PM₁₀滞后04天浓度每增加，出车次数增加0.35%（95%CI：0.05% - 0.66%）。
结论
中国北方室外颗粒物（PM₂.₅和PM₁₀）浓度与因神经系统疾病导致的急救车出车风险增加显著相关。
