OBJECTIVE
To study the association between particulate matter less than 10 micron in aerodynamic diameter (PM(10)) and daily mortality among urban population in Tianjin.
METHODS
We collected data of air quality, daily mean temperature and relative humidity, and daily cause-specific death counts, and used generalized additive models to explore the relationship between ambient particulate matter and daily mortality, after adjusting the effects of long-term and seasonal trend, weather conditions and other gaseous pollutants, such as sulfur dioxide and nitrogen dioxide.
RESULTS
An increase of 10 µg/m(3) in PM(10) was associated with 0.45% (95%CI: 0.21 - 0.69) non-accidental morality, 0.60% (0.29 - 0.91) circulatory morality and 0.82% (0.04 - 1.61) respiratory morality, respectively.
CONCLUSION
Our findings indicated that the extent of exposure to PM(10) was significantly associated with daily mortality in urban population in Tianjin, especially with the mortality rates on circulatory and respiratory diseases.
目的
研究天津市城市人口中空气动力学直径小于10微米的颗粒物（PM10）与每日死亡率之间的关联。
方法
我们收集了空气质量、日平均温度和相对湿度以及每日特定病因死亡人数的数据，并在调整了长期和季节性趋势、天气状况以及其他气态污染物（如二氧化硫和二氧化氮）的影响后，使用广义相加模型来探讨环境颗粒物与每日死亡率之间的关系。
结果
PM10每增加10μg/m³，分别与0.45%（95%置信区间：0.21 - 0.69）的非意外死亡率、0.60%（0.29 - 0.91）的循环系统疾病死亡率和0.82%（0.04 - 1.61）的呼吸系统疾病死亡率相关。
结论
我们的研究结果表明，天津市城市人口中PM10的暴露程度与每日死亡率显著相关，尤其是与循环系统和呼吸系统疾病的死亡率相关。
