A factor analysis model based in a multivariate statistical analysis was used as a complement of correlation
coefficients to determine the number and the type of metal sources associated to the receptor monitoring site in
the urban zone of Tampico, Tamaulipas, Mexico. To obtain the possible metal sources, 11 variables including
metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb, Ti, V and Zn) and particulate matter (PM10) data were used. Results of
correlation coefficients showed strong relation between metals as V-Ni and Cu-Zn with 0.89 and 0.85,
respectively. In Addition, Cd-Cr and Fe-Ti showed good correlation coefficients of 0.73 and 0.74, respectively. Pb
and Zn showed correlation among several metals as Cu, Ni, Fe and Mn. These correlations were verified with the
help of factor analysis. 4 factors (possible sources) explaining 85% of the total variance were found. Cu, Mn and
Zn were principally found in the first factor, whereas Cd and Cr were mainly found in the second source. V-Ni and
Fe-Ti were related to the next sources. Thus, the metals associated could be related to industrial activities and
dust suspension near the sampling zone. Meteorological parameters as wind direction and wind velocity were
used in addition to correlation coefficients and factor analysis to study the possible sources of these metals.
