The need for comprehensive air pollution studies in Lagos cannot be overemphasized in view of the level of industrialization of the city and its nearness to the ocean. Air particulate samples collected with a high-volume air sampler at three locations in Lagos, Nigeria were analyzed by the combination of wavelength-dispersive X-ray fluorescence and atomic absorption spectroscopy methods. Elemental concentrations were subjected to factor analysis for source identification and chemical mass
