Resumen

We collected sediment samples in Igarapé do Quarenta (IQ40) to extraction of heavy metal into five fractions: exchangeable, bound to carbonates, bound to Fe-Mn oxides, bound to organic matter, and residual according to Tessier et al. (1979). To the sequential extraction procedure in a 50 mL tube added 1 g of sediment sample. To analyze from heavy metal present into muscle and liver from Hoplosternumlittorale, we collected twenty species and analyzed heavymetals in Hoplosternumlittoraleand sediment sequential fractions by Flame Absorption Atomic Spectrometry (FAAS). As a tool alternative statistical analysis, we suggest the use of beanplotin the results obtained by sequential fraction. The results show high heavy concentrations in the exchangeable, bound to carbonates, bound to iron and manganese oxides, bound to organic matter fractions. The beanplot shows being an important tool to understand the behavior of the heavy metal in sequential fractions present in contaminated sediment. High Zn and Cu concentration found exchangeable fraction explain the high concentration in muscle and live fromHoplosternumlittorale.
