(Universidade Federal de Santa MariaBrasilCiência e Tecnologia dos AlimentosUFSMPrograma de Pós-Graduação em Ciência e Tecnologia dos AlimentosCentro de Ciências Rurais, 2014-05-30)
Most of the people do not reach the recommended intake for calcium (Ca), which is a mineral
essential for bone development, muscle contraction, blood coagulation, cell permeability and several
other functions. Hen eggshells ...
Assessment of phase distribution and removal of metals in anaerobic digesters
(2021-01-01)
A determination of the mobility and bioavailability of metals could provide more comprehensive knowledge about the real environmental potential of anaerobic biodigestion and health risks associated with inappropriately ...
Bioaccumulation of heavy metals in mesozooplankton from a human-impacted south western Atlantic estuary (Argentina)
(Sears Foundation Marine Research, 2019-01-01)
The total metal concentrations (Cd, Cu, Pb, Zn, Mn, Ni, Cr, and Fe) in the mesozooplankton (200 μm–2 mm) were studied for a year in a human-impacted estuary strongly affected by urban and industrial discharges located in ...
Metal speciation in sediments from crude oil prospecting in the coastal area of ondo state, nigeria
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2013)
Information obtainable from metal speciation is far more valuable with respect to bioavailability, toxicity and fate of metals than information from total metal data. Therefore, metal speciation on sediment to assess the ...
The geomicrobiology of iron, cobalt, nickel and manganese in lateritic tropical soils from the Santa Elena Peninsula, Costa Rica
(2019)
There is an increasing interest in the biogeochemistry of metals, like cobalt, fuelled by the growing need for batteries and other high technology products. Bioprocessing of Co has been proposed to improve its recovery ...
