Abstract
Black Carbon (BC) is an atmospheric pollutant categorized as one of the main contributors to climate change, due to the ability of its particles to absorb solar radiation. The objective of this study was to evaluate the concentrations of BC in the city of Barranquilla, Atlántico, analyzing the influence of its possible sources, for this, a sample was carried out with an AE33 Aethalometer for 5 months (May-September 2019). The sources were identified by calculating the Ångström Absorption Exponent (AAE), while BC transport was calculated with modeling using the Hysplit trajectory model. The average BC concentration was 1.09 ±1.03 µg/m3 , with the highest levels occurring during business days, with high peaks between 6:00 am and 9:00 am. The results obtained for AAE confirmed that the combustion of fossil fuels predominats with a contribution of 58%, for the burning of biomass 6% and for the influence of the two sources in the same period 36%. The modeling revealed the burning points, which determined that the greatest contribution to BC concentrations came from the East and Northeast of the city. BC concentrations and meteorological parameters presented a positive relationship with temperature and solar radiation, and a negative relationship with relative humidity and precipitation. The results indicate that the emission of BC in the city is mainly associated with vehicular traffic, where on certain days the rates are relatively high and can generate harmful effects on the population's health.
