Trace Level Vanadium Determination Using Thermal Lens Spectrophotometry
(Mikrochim. Acta, 2013)
Effects of dietary trace mineral sources and levels fed to layers in their second laying cycle on the quality of eggs stored at different temperatures and for different periods
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2010-12-01)
This study aimed at evaluating the effects of trace mineral levels and sources supplemented to diets fed to semi-heavy layers in their second laying cycle on the quality of eggs stored for 14 days at different temperatures. ...

Narrowing the interface between sample preparation and electrochemistry: Trace-level determination of emerging pollutant in water samples after in situ microextraction and electroanalysis using a new cell configuration
(2018-06-10)
In this work, a new cell configuration that enables the in situ integration of sample preparation and electrochemical detection prior analysis at trace-level is described. To perform the microextraction, a green chemistry ...
Trace metal concentrations in the hair of Zalophus californianus pups and their relation to feeding habits
(Biological Trace Element Research, 2008)
The levels of six trace metals (Hg, Se, Pb, Cu, Fe, and Zn) were measured in the hair of California sea lion pups from eight rookeries in the Gulf of California, with the aim of relating these levels with the animals feeding ...
Use of Cathorops spixii as bioindicator of pollution of trace metals in the Santos Bay, Brazil
(SPRINGER, 2009)
In the present study Cathorops spixii, was evaluated as a bioindicator fish for trace metal pollution. Concentrations of cobalt (Co), iron (Fe), selenium (Se) and zinc (Zn) were determined by Instrumental Neutron Activation ...
