【摘要】：目的探討銀川市大氣顆粒物污染水平及其對(duì)居民循環(huán)系統(tǒng)疾病死亡的暴露-反應(yīng)關(guān)系。方法通過收集銀川市2013—2015年空氣質(zhì)量監(jiān)測(cè)數(shù)據(jù)、氣象監(jiān)測(cè)數(shù)據(jù)和居民死亡監(jiān)測(cè)資料,采用廣義相加模型,分析銀川市大氣顆粒物物對(duì)與居民循環(huán)系統(tǒng)疾病死亡的暴露-反應(yīng)關(guān)系。結(jié)果大氣PM_(10)和PM_(2.5)年均濃度均超過GB 3095—2012《環(huán)境空氣質(zhì)量標(biāo)準(zhǔn)》二級(jí)標(biāo)準(zhǔn)。大氣PM_(10)和PM_(2.5)濃度每升高10μg/m~3對(duì)人群循環(huán)系統(tǒng)疾病死亡的超額危險(xiǎn)度分別為0.56%(95%CI:0.15%~0.97%),1.33%(95%CI:0.46%~2.21%);大氣PM_(10)和PM_(2.5)濃度對(duì)小于65歲組的循環(huán)系統(tǒng)疾病死亡的影響無統(tǒng)計(jì)學(xué)意義(P0.05),對(duì)65歲以上年齡組人群循環(huán)系統(tǒng)疾病死亡的超額危險(xiǎn)度分別在滯后7、5 d時(shí)達(dá)到最大效應(yīng),分別為1.24%(95%CI:0.21%~2.28%)和0.57%(95%CI:0.08%~1.06%);大氣PM_(10)、PM_(2.5)濃度對(duì)女性循環(huán)系統(tǒng)疾病死亡的超額危險(xiǎn)度高于男性。結(jié)論研究期間銀川市大氣顆粒物濃度較高,且對(duì)人群循環(huán)系統(tǒng)疾病死亡存在一定的暴露-反應(yīng)關(guān)系。
[Abstract]:Objective to investigate the level of atmospheric particulate pollution and the relationship between exposure and response to circulatory diseases in Yinchuan. Methods by collecting air quality monitoring data, meteorological monitoring data and resident death monitoring data from 2013 to 2015 in Yinchuan City, a generalized additive model was used. The relationship between exposure and death of atmospheric particulates and circulatory diseases in Yinchuan was analyzed. Results the average annual concentrations of PM_ (10) and PM_ (2.5) in the atmosphere exceeded the second grade of GB 3095-2012. For each 10 渭 g/m~3 increase in atmospheric PM_ _ (10) and PM_ _ (2.5) concentrations, the excess risk of death from circulatory diseases in the population was 0.56% (95 CI: 0.15 0.97%). 1.33% (95% CI: 0.46%); The effects of atmospheric PM_ _ (10) and PM_ _ (2.5) concentrations on the mortality of circulatory diseases in patients younger than 65 years old were not statistically significant (P0.05). The excess risk of circulatory disease death in the age group over 65 years old reached the maximum effect at the time of delay of 7d or 5d, respectively. It was 1.24% (95% CI: 0.21 and 2.28%) and 0.57% (95% CI: 0.08% 1.06%); Atmospheric PM_ (10) and PM_ (2. 5) concentrations had higher excess risk of circulatory disease death in women than in men. Conclusion during the study period, the concentration of atmospheric particulate matter in Yinchuan City was high, and there was a certain relationship between exposure and response to the death of circulatory diseases in the population.
