%X this study analyzed the levels of cadmium, lead, copper, chromium, manganese, mercury, and zinc in leachate from the ribeir£żo preto landfill site in s£żo paulo state, brazil. samples were taken from runoff tanks in module i (operating from 1989 to 2000) and module ii (operating since november 2000). metal levels were measured by atomic absorption spectrophotometry at the university of s£żo paulo in ribeir£żo preto (university hospital). results were compared to the maximum limits for metal concentration in liquid effluents set by ruling 357/2005 of the national environmental council (conama). the study also investigated whether there was any attenuation in metal concentrations in the leachate, considering differences in the life spans of the various ribeir£żo preto landfill site modules. metal levels in the samples were within the maximum limits for cadmium, chromium, copper, mercury, and manganese, but lead and zinc were above the limits set by the above-mentioned ruling.
