Air quality (AQ) is a major challenge in Bogota. Frequently, PM ambient standards are exceeded in the southwestern areas of the city. An AQ modeling plataform was estalished in Bogota aiming to understand sources of pollution and evaluate control strategies. Modeling fields allow to estimate pollutant concentrations outside the AQ monitoring network range. Health impacts can be assessed at the city domain using results from the model, along with epidemilogical and demographics data.
In this work, we estimate the health burden of air pollution in Bogota and assess the economic cost. A maximum vale of 67.5 ug/m3 of PM.5 was estimated by the model in the southwestern areas of the city. The PM2.5 average concentration resulted in 1746 city-wide deaths, with a cost of 1000 million of dollars.
The large impact of air pollution in Bogota has motivated the environmental authority to define Urban Zones for Better Air (ZUMA in Spanish), where intersectoral actions will be concentrated to improve air quality, mitigate emissions and reduce the risk to people's health from air pollution.
