Abstract

The chemical mass balance (CMB) was applied to the volatile organic compounds (VOC) data base collected in Mexico City during the spring of 1996 and 1997 in conjunction with different source profiles collected during May through November 1997. The study of the contribution of VOC to the atmospheric pollution in large cities and its control has been conducted using the CMB receptor model. Samples of ambient air were simultaneously collected at three different sites, using stainless steel canisters and then analysed by gas chromatography with flame ionisation detection system. Each ambient sample was evaluated for the contribution from different sources of
