Preliminary Investigation on the Atmospheric Dispersion of Pollutants Due to Ferraz Fire

Abstract

Here we present a summary of the atmospheric modeled data for gas and total particulate matter dispersion and deposition due to the re at Ferraz Station on February 25th, 2012. e main purpose is to permit a preliminary diagnosis of the main areas potentially impacted in Admiralty Bay and vicinities for purposes of future decision-making and scienti c planning. In this way enable an investigation of the area that came under the impact of the re emissions and better detail the levels of contamination of biotic and abiotic components of the local environment. is present version of the model takes into account the meteorological data acquired at the time of the re, as well as observational records and the geomorphology. e great uncertainty assigned to the model refers to the emissions factor due to the high complexity of materials present in Ferraz Station and a subjective estimate of the temperature of the materials ignited during the re. us, the basic function of the model is to describe the spatial behavior of the plume of pollutants and not necessarily the absolute values of the deposition uxes.
