Multitemporal Analysis of the Influence of PM<sub>10</sub> on Human Mortality According to Urban Land Cover
High urbanization and a consequent change in land cover can lead to a deterioration in air quality and generate impacts on public health. The objective of this paper is to provide a multitemporal analysis of the influence of particulate matter ≤ 10 μm (PM<sub>10</sub>) on human mortality...

| description | High urbanization and a consequent change in land cover can lead to a deterioration in air quality and generate impacts on public health. The objective of this paper is to provide a multitemporal analysis of the influence of particulate matter ≤ 10 μm (PM<sub>10</sub>) on human mortality from the land cover variation in a Latin American megacity. Six monitoring stations (monitoring daily PM<sub>10</sub> concentration, increases in daily mortality (IDM), and land cover) were established throughout the megacity. The results suggest that for every 10% increase in vegetation cover, the daily PM<sub>10</sub> concentration and IDM decreases by 7.5 μg/m<sup>3</sup> and 0.34%, respectively. Moreover, it is evident that the monitoring station with the lowest vegetation cover (8.96 times) shows an increase of 1.56 times and 4.8 times in the daily PM<sub>10</sub> concentration and IDM, respectively, compared with the monitoring station with the highest vegetation cover (46.7%). It is also suggested that for each increase of 100 inhabitants/hectare in population density, the daily PM<sub>10</sub> concentration and IDM increases by 9.99 µg/m<sup>3</sup> and 0.45%, respectively. Finally, the population densification of the megacity possibly implies a loss of vegetation cover and contributes to the increase in PM<sub>10</sub> and IDM. |
