It is very important to study the occurrence of high levels of particulate matter due to the potential harm to people's health and to the environment. In the present work we use a non-homogeneous Poisson model to analyse the rate of exceedances of particulate matter with diameter smaller that 2.5 microns (PM2.5). Models with and without change-points are considered and they are applied to data from Bogota, Colombia, and Mexico City, Mexico. Results show that whereas in Bogota larger particles pose a more serious problem, in Mexico City, even though nowadays levels are more controlled, in the recent past PM2.5 were the ones causing serious problems.

应用非均匀泊松模型研究墨西哥城和波哥大的 PM2.5 超标情况

由于对人类健康和环境的潜在危害,研究高浓度颗粒物的发生非常重要。在目前的工作中,我们使用非均匀泊松模型来分析直径小于 2.5 微米的颗粒物(PM2.5)。考虑了有和没有变化点的模型,并将它们应用于来自哥伦比亚波哥大和墨西哥墨西哥城的数据。结果表明,尽管在波哥大,较大的颗粒会造成更严重的问题,但在墨西哥城,尽管现在的水平受到了更多控制,但在最近过去的 PM2.5是那些造成严重问题的人。
