Geochemical distribution and threshold values determination of heavy metals in stream water in the sub-basins of Vermelho and Sororó rivers, Itacaiúnas River …
Geochemical survey in the Vermelho (VSB) and Sororó (SSB) sub-basins of the Itacaiúnas
basin in southeastern Amazonian region has shown that the physical-chemical parameters
of stream water do not display accentuated variations between the rainy and dry seasons.
Except for Fe and Mn, in general most metals show low contents in water and evidences of
significant contamination were not observed. Higher contents were mostly registered during
the rainy season. Fe is regularly distributed in water in the studied area and the increase of …
