Potentially mobile of heavy metals on the surface sediments in tropical hyper-s...
SILVA,CARLOS A. RAMOS E; FONSECA,ESTEFAN M. DA; GROTTO,BEATRIZ W.; SOUZA,FLAVO E.S. DE; BAPTISTA NETO,JOSÉ A.ABSTRACT Estuarine sediments represent important pools of trace metals, released from both anthropogenic and natural sources. Fluctuations in the water column physicochemical conditions, on the other hand, may transfer metals from solid to liquid compartment and resulting in contamination of the surrounding environment. The present research was carried out to evaluate the weakly bounded heavy metal levels in tr...
The Role of the Humic Substances in the Fractioning of Heavy Metals in Rodrigo ...
FONSECA,ESTEFAN M. DA; BAPTISTA NETO,JOSÉ A.; MCALISTER,JOHN; SMITH,BERNARD; FERNANDEZ,MARCOS A.; BALIEIRO,FABIANO C.One of the main results of the processes related to urbanization is the contamination of the adjacent water bodies. Inserted in this context, the Rodrigo de Freitas lagoon is situated in the south zone of the city of Rio de Janeiro. This ecosystem receives several inputs containing all sorts of pollutants, including heavy metals. The present work aimed to study the partitioning of heavy metals in the sediments ...
