Contamination of port zone sediments by metals from Large Marine Ecosystems of Brazil
(Pergamon-Elsevier B.V. Ltd, 2012-03-01)
Sediment contamination by metals poses risks to coastal ecosystems and is considered to be problematic to dredging operations. In Brazil, there are differences in sedimentology along the Large Marine Ecosystems in relation ...
Evidence for a correlation between total lead concentrations in soils and the presence of geological faults
The emission of radon gas in regions of geological faults, during the radioactive decay of uranium and thorium, results in the formation of lead isotopes 210Pb, 208Pb, 207Pb and 206Pb. As a consequence, the lead contamination ...

Potential accumulation of contaminated sediments in a reservoir of a high-Andean watershed: Morphodynamic connections with geochemical processes
Rapid changes due to anthropic interventions in high-altitude environments, such as the Altiplano region in South America, require new approaches to understand the connections between physical and geochemical processes. ...
Integration of geoelectric and geochemical data in the evaluation of natural attenuation in a diesel contaminated site in Sao Manuel (Brazil)
(Inst Geophysics Unam, 2017-07-01)
Geophysics is a very relevant investigation tool in conjunction with chemical analysis, during the diagnosis and monitoring of contamination in the geological environment. This paper presents the results of DCdefine ...
