As part of the EMECAM Project, the objective of this study is that of assessing the impact of air pollution on the daily mortality in Seville throughout the 1992-1996 period.
During the 1992-1996 period, readings were taken daily of the amounts of SO2, particles in suspension (PM10) and NO2 present in the air in the city of Seville, in addition to the number of deaths daily due to different causes. For analyzing this data, a multivariable Poisson regression model was used for modeling each one of the causes of death in terms of the air immission readings, controlling other confusion-causing variables.
A relationship was found to exist between the rises in the NO2 levels and the daily death rate throughout the months of May to October. For each 10 micrograms/m3 rise, the risk of death or all causes showed a 2% rise, the same rise in the NO2 levels leading to a 3% rise in the risk of death resulting from cardiovascular diseases.
A relationship exists between the levels of NO2 air pollution and the daily death rate in Seville. The findings provide scientific knowledge and information which can be of use for preventing the impact of air pollution on human health.
作为EMECAM项目的一部分，本研究的目的是评估1992年至1996年期间空气污染对塞维利亚每日死亡率的影响。
在1992年至1996年期间，除了记录塞维利亚市每日因不同原因导致的死亡人数外，还每日测量空气中二氧化硫、悬浮颗粒物（PM10）和二氧化氮的含量。为了分析这些数据，使用多变量泊松回归模型，根据空气污染物排放读数对每一种死亡原因进行建模，并控制其他混淆变量。
发现二氧化氮水平的上升与5月至10月期间的每日死亡率之间存在关联。每上升10微克/立方米，所有原因导致的死亡风险上升2%，相同的二氧化氮水平上升导致心血管疾病死亡风险上升3%。
塞维利亚的二氧化氮空气污染水平与每日死亡率之间存在关联。这些发现提供了科学知识和信息，可用于预防空气污染对人类健康的影响。
