The purpose of this research is to deepen the investigation of atmospheric impact as a result of aerosol and gas emissions at Comandante Ferraz Brazilian Antarctic Base (henceforth EACF). As a consequence of a campaign during 2009/2010 summer and re-analysis of 1998 filters (whereby there became available an annual set of continuous samples), levoglucosan (the product cellulose pyrolysis) as an indicator of burning of organic material by the Brazilian Station was verified. The numeric model of atmospheric dispersion used for Admiralty Bay was suitable for study of the impact on the atmosphere in Admiralty Bay and in zoned areas of biological importance within the Antarctic Specially Managed Area of King George Island, using a simulation with stations and ships operating simultaneously. The preliminary results of the chemical analyses for carbonyls and BTEX have shown that the direct atmospheric impact zone of EACF, due to these chemicals, is restricted to a radius of a maximum of 400 m, falling sharply in all directions

Considering new parameters in the study of atmospheric impacts at Admiralty Bay
