N2 - Using the Emission Inventory of Tamaulipas State in Mexico, a Geographical Information System (GIS) methodology was developed for the municipality of Altamira to help in the identification of PM10 and metal emission sources considering the meteorological conditions from April to November 2005. The metal content in PM10 was analyzed for the first time in the industrial zone of Altamira, Tamaulipas Mexico. Particulate matter less than 10 μm of aerodynamic diameter was collected every six days in quartz microfibre filters with a high volume sampler (Andersen). 10 metals (Cd, Cr, Cu, Fe, Mn, Pb, Ni, Ti, V and Zn) were evaluated in this industrial zone using an ICP-OES. Metal content in PM10 was extracted from the filters according to the method USEPA IO-3.1. All the reagents and laboratory material were ultrapure and certified class "A". Despite the fact that Altamira atmosphere is influenced by many different kind of industries, PM10 and lead concentrations in Altamira did not exceed Mexican regulations during the studied period as they were always less than 120 μg/m3 and 1.5 μg/m3 in 24 hrs respectively. PM10 concentrations ranged from 23 and 92 μg/m3. The highest concentrations of metals were showed by Fe, Mn and Ti with approximately 2.0, 0.6 and 0.3 μg/m3 respectively. The presence of V, as well as Mn, suggest that a refinery located near the sampling zone is the main source for those metals.
