Todos os anos Portugal é assolado por vários incêndios florestais. Estes acarretam enormes consequências a nível ambiental, social e económico. Este trabalho visa avaliar a influência desses incêndios na poluição ambiental. A análise de dados relativos ao número de ocorrências e área atingida ao longo da década (2003-2012), bem como das consequências destes incêndios na poluição atmosférica, nomeadamente nas concentrações de gases e partículas na camada limite, dar-nos-á uma melhor perceção da dimensão deste problema. Para além dos efeitos imediatos dos incêndios florestais, existem também os efeitos a médio e longo prazo. Nestes enquadram-se a erosão dos solos e as alterações de quantidade e qualidade dos recursos hídricos das regiões afetadas. O estudo estatístico dos parâmetros atrás referidos e uma aprofundada pesquisa bibliográfica sobre as consequências destes incêndios permitirão a sugestão de algumas medidas que possam reduzir o número de ocorrências, a sua magnitude e a sua influência na qualidade ambiental; Influence of forest fires on environmental pollution Abstract: Every year Portugal is devastated by a series of wildfires. These have enormous environmental, social and economical consequences. This thesis aims to evaluate the influence of forest fires on environmental pollution. The statistical analysis of the number of occurrences and the affected area during the decade (2003-2012), as well as the impact on air pollution, particularly in concentrations of gases and particles in the boundary layer, will give us a better view of the problem. The impact that the forest fires may have on soils and hydric resources from the affected regions will also be analyzed. The analysis of the parameters mentioned above, and a literature search on the impact of these fires will lead to a better understanding of the real impact of these events, which will allow the presentation of some measures that can reduce the number of occurrence, its magnitude and its influence on environmental quality.
