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
