espanolEn este trabajo se determinaron in situ las concentraciones de material particulado (PM10) en dos puntos de la ciudad de Bogota, uno en la zona centro y el otro en la zona occidental de la misma durante un periodo de muestreo realizado en el segundo semestre del 2018 (30 dias validos de muestreo). Igualmente se evaluo la correlacion de las variables meteorologicas y la variable concentracion de PM10, de ambos puntos en cuestion mediante el software libre MiniTab. Contrario a la preconcepcion que se tenia debido a la presencia del alto desarrollo urbanistico en el punto de la zona centro y a una amplia zona verde en el punto de la zona occidental las concentraciones del contaminante fueron constantemente superiores al occidente de la ciudad. La direccion del viento predominante en la zona centro que genera un arrastre del contaminante hacia la zona occidental de la ciudad y la peatonalizacion de corredores viales fueron argumentados como las causas plausibles de las diferencias. Un total de 112 y 14 muertes prematuras anuales por cada 100.000 habitantes por causa de la exposicion a la concentracion del contaminante determinada que fueron estimadas para la zona centro y occidental correspondientemente. EnglishIn this work, the concentrations of particulate matter (PM10)were determined in situ at two points in the city of Bogota, one in the central zone and the other in the western zone during a sampling period carried out in the second semester of 2018 (30 valid sampling days). The correlation of meteorological variables (wind speed and direction, temperature and precipitation) and thePM10concentration variable of both points in question were also evaluated using the free software MiniTab. The impacts on the health of the exposed population were determined using the dose-response relationship methodology for several morbidity indicators, as well as for mortality. Average concentrations of21.43±0.76μg/m3and33.58±0.51μg/m3of PM10were obtained in the central and western zones respectively. Contrary to the preconception that was had due to the presence of the high urban development in the point of the center zone and to awide green zone in the point of the western zone the concentrations of the pollutant were constantly superior to the west of the city. The predominant wind direction in the central zone (South East) that generates a drag of the pollutant towards the western zone of the city and the pedestrianization of road corridors were argued as the plausible causes of the differences. A total of 112 and 14 annual premature deaths per 100,000 inhabitants due to PM10exposure were estimated for the central and western areas accordingly. |
