Resumo
The Metropolitan Region of Sao Paulo (Brazil) with a population 16.322 million people (1995 estimate)(2) living a in a area of 8,051 km2 and most of them concentrated in the city of Sao Paulo with 9.8 million people and 4.6 million cars, although with an air quality better than some other Latin American megacities such Mexico and Santiago do Chile is still under an air quality that exceeds the national air quality standards (1, 2, 3). In 2/17/1993 Brazilian Petroleum Company (PETROBRAS) and the Bolivian Petroleum Company (Yacimientos Petroliferos Fiscales Bolivianos - YPFB) signed an agreement to bring natural gas from Bolivia to the south and southeast of Brazil (6). The end of the construction of the gas pipeline will be in 1999, and it will deliver 4 million Nm3/day of natural gas to COMGAS - Sao Paulo State Gas Company. This amount will increase to 8.1 million Nm3/day by the year 2006, that will be sufficient to supply the Sao Paulo Metropolitan Region market need at that time (6). In this study an estimate of the influence in the air quality was performed supposing the substitution of fuel oil by natural gas in industry and also in diesel buses. The results showed that there will be benefits in relation to sulfur dioxide, PM10, greenhouse gases and trace elements, and negligible effects in relation to NOx, NMTOC and carbon monoxide.
