摘要: The current study aimed at quantifying arsenic and lead in feathers from three passerine species that are residents areas exposed to mining activities (Toxostoma curvirostre, Campylorhynchus brunneicapillus, Melozone fusca). Lead As contents bird superficial soil samples were measured with AAS. Levels of these metals compared between sites unexposed mining. Possible correlations Pb also investigated. Soil metal concentrations significantly higher near sites, showed a behavior similar those recorded for samples. Individual birds polluted had mean feather comparison non-polluted sites; no differences among species. This work constitutes basis monitoring contaminants, future toxicological studies attempting understand the impact some may have on populations.
