dc.description.abstractTo evaluate possible variations over time (2006-2013) in trace element levels in livers from adult specimens of great egret from the São Paulo Metropolitan Region (SPMR), recent data and published data have been used. The elements Br, Cl, Co, Cs, Cu, Fe, K, Mg, Mn, Na, Rb, Se and Zn were determined by Neutron Activation Analysis (NAA) and the toxic elements Cd and Hg by Atomic Absorption Spectrometry (AAS). The large inter annual variations observed for several elements showed the importance of expanding the time period for this analysis as the series is considered short (<10 years). However, non-significant increase of Br, Cu, Mn, Fe and Zn and a decrease in Cd, also non- significant, were observed at the end of the series. The concentration relations with sex and mass of the birds were also assessed. Females presented lower concentrations of Br, Co, Cs, Se and Zn and it may be related to metabolic differences, detoxification pathways, and other factors. No relationship between body mass and element levels were observed. Obtained results demonstrated the importance of temporal monitoring of trace elements in livers of great egrets, especially for the results obtained for Cu, Fe and Zn, since the contamination by these elements in the region should be considered. The present study is the first relating contaminant level with conditions of birds in the region, encouraging future studies that evaluate this issue.pt_BR
