Environmental evaluation of metals in sediments and dragonflies due to sugar cane cultivation in neotropical streams
(Springer, 2008-11-01)
The use of fertilizers, containing different metals ions such as lead(II), chromium(III), cadmium(II), copper(II) and zinc(II), in the soil, for sugar cane cultivation, may cause impacts on the hydric resources of the ...

The effect of hydrographs on bed load transport and bed sediment spatial arrangement
(AMER GEOPHYSICAL UNION, 2012)
Field measurements of sediment transport in gravel bed rivers often reveal hysteretic effects due to differences in sediment availability between the rising and falling limbs of a flood hydrograph. However, only a small ...
A 210Pb chronological study in sediments from poços de caldas alkaline massif (PCAM), Brazil
(2018-07-01)
The Constant Flux and Constant Sedimentation (CF:CS) of supported/excess 210Pb model was successfully used to study sediment profiles from Antas stream, located in the region of Poços de Caldas city, Minas Gerais State, ...
Mercury fractionation in stream sediments from the Quadrilátero Ferrífero gold mining region, Minas Gerais State, Brazil

Biocatalysed acidification and metal leaching processes in sediments of polluted urban streams
(Inderscience Enterprises, 2014-04)
Sediments of fluvial streams are a sink for pollutants such as heavy metals and organic recalcitrant compounds. In anoxic conditions, sulphide generation and alkalinisation cause precipitation of heavy metals. The redox ...
