空气颗粒物与人群死亡率暴露-反应关系的特征

Character of Exposure-Response Relationship between Particulate Matter and Population Mortality

目前,针对空气颗粒物与人群死亡率暴露-反应关系特征的研究已经成为空气污染流行病学研究的关键和难点问题之一。暴露-反应关系特征是指暴露-反应关系曲线的形状及是否存在阈值浓度。该文对国内外空气颗粒物与人群死亡率暴露-反应关系特征研究进行了综述,空气颗粒物暴露对人群死亡率的影响尚未发现阈值浓度的存在,暴露-反应关系曲线的形状也需要进一步的研究。我国开展颗粒物与人群死亡率暴露-反应关系研究正面临难得的机遇。

The character of exposure-response relationship between particulate matter and population mortality has been one of the critical and difficult problems in air pollution epidemiological study. The character of exposure-response relationship included the shape of the exposure-response relationship and the existence of the threshold concentration. In this paper, the recent relevant researches on the character of exposure-response relationship between particulate matter and population mortality were reviewed. The threshold concentration of particulate matter for mortality was not found and the shape of the exposure-response curve need to be further studied. Now, in China, we are facing a good opportunity for researching the exposure-response relationship between particulate matter and population mortality.
