Introduction	This study evaluated fine atmospheric particulate matter (PM2.5) collected from the urban industrialised area of Guaynabo and the less polluted site of Fajardo in Puerto Rico. The samples, gathered between November 2000 and September 2001, were analysed for trace metals such as arsenic, cadmium, copper, iron, nickel, lead, vanadium, and zinc using atomic absorption. Elemental and organic carbon levels were also assessed. Results indicated that all metals, except for iron, were higher in Guaynabo compared to Fajardo. Notably, nickel and vanadium levels in Guaynabo were elevated compared to other cities, potentially contributing to respiratory issues in the region. Multivariate analysis revealed strong relationships between the elements in both Guaynabo and Fajardo, with distinct patterns of association.
