ZAFRA-MEJIA, Carlos Alfonso; RODRIGUEZ-MIRANDA, Juan Pablo y RONDON-QUINTANA, Hugo Alexander. The relationship between atmospheric condition and human mortality associated with coarse material particulate in Bogotá (Colombia). LogosCyT [online]. 2020, vol.12, n.3, pp.57-68. Epub 27-Nov-2020.

This article studies the relationship between atmospheric condition (AC) and human mortality rate associated with coarse particulate matter (PM10) in a high-altitude mega-city (Bogotá-Colombia). Information was collected from three automatic monitoring stations equipped with measuring instruments for PM10, temperature, solar radiation and wind speed. The sampling period lasted six years. The results showed the best possible scenario for the maximum hourly concentrations of PM10 (52.3-135 μg/m3). These events occurred during daytime periods where the predominant AC was between unstable and very unstable. The risk from exposure to PM10 showed that February>March>January were the highest risks. These months showed PM10 concentrations 35.9% higher than those observed during the months of lower risk (August>June>July). A higher mortality rate (+2.0%) was suggested in urban sectors with less atmospheric instability (AI) and predominance of impervious cover compared to sectors with higher AI and predominance of vegetated cover.
