(Elsevier B.V., 2014)
Investigation of Protein Biomarkers and Oxidative Stress in Pinirampus pirinampu Exposed to Mercury Species from the Madeira River, Amazon-Brazil
(2022-04-01)
In recent decades, the scientific community has widely debated the contamination of fish in the Amazon region by mercury species. As the diet of riverside populations in the Amazon region is based mainly on fish, these ...
Reduction of mercury(II) by tropical river humic substances (Rio Negro) - A possible process of the mercury cycle in Brazil
(Elsevier B.V., 2000-12-04)
The evolution of elemental Hg from its environmental compounds has already been supposed to be an important process within the global mercury cycle. The present study characterizes the abiotic reduction of Hg(II) ions by ...

Natural and anthropogenic variations in atmospheric mercury deposition during the Holocene near Quelccaya Ice Cap, Peru
(Wiley, 2014)
Mercury (Hg) is a toxic metal that is transported globally through the atmosphere. Emissions of Hg from mineral reservoirs and recycling between soil/biomass, oceans, and the atmosphere are fundamental to the global Hg ...
Mercúrio em solos do Sudeste brasileiro : interações e avaliação da vulnerabilidade perante mercúrio elementar e mercúrio (II)
(Universidade Federal de Minas GeraisUFMG, 2015-02-25)
This study aimed to evaluate the influence of physical and chemical soil characteristics of southeastern Brazil, without anthropogenic influence, in the natural mercury content of soils and retention of atmospheric mercury ...
Total Mercury Determination in Muscle and Liver Tissue Samples from Brazilian Amazon Fish Using Slurry Sampling
(2018-08-01)
This paper presents a slurry sampling method for total mercury determination by graphite furnace atomic absorption spectrometry (GFAAS) in tissue of fish from the Amazon. The tissue samples were lyophilized and macerated, ...
