INVENTÁRIO DE EMISSÕES VEICULARES DA REGIÃO METROPOLITANA DE SALVADOR PARA O ANO DE 2010

Abstract

Vehicular emission inventories are extremely important tools to quantify emissions assess trends, ensure sufficient information for studies of atmospheric dispersion and assessing environmental impacts. This work sought to develop the vehicle emissions inventory for the metropolitan area of Salvador, the third largest city in Brazil, for the year 2010, along with its statistical uncertainty analysis. It was used the methodology of the European Environment Agency, that relate the emissions ratings with the vehicles average mileage. The results indicates the emission of approximately 369,000 (± 56%) tons of Carbon Monoxide, 30,600 (± 43%) tons of de hydrocarbons, 93,600 (± 30%) tons of nitrogen oxides, 1,000 (± 31%) tons of Sulfur Oxides and 3,000 (± 19%) tons of particulate matter. Based on the results, it is intended to support the development of the vehicular pollution Control programme (VPCP) in Bahia, Brazil.
