Developmental lead exposure: behavioral alterations in the short and long term
(Elsevier B.V., 2001-09-01)
Wistar dams were exposed to 500 ppm of Pb, as Ph acetate, or 660 ppm Na acetate in drinking water during pregnancy and lactation. Male pups at 23 (weaned) or 70 days (adult) of age were submitted to behavioral evaluation ...

Determination of cadmium and lead in table salt by sequential multi-element flame atomic absorption spectrometry
(Elsevier, 2005-02-28)
In the present paper, a simultaneous pre-concentration procedure for the sequential determination of cadmium and lead in table salt samples using flame atomic absorption spectrometry is proposed. This method is based on ...
An on-line system for preconcentration and determination of lead in wine samples by FAAS
(2002-09)
A flow injection method has been developed for the direct determination of free available Pb(II) and total Pb content in wine samples. The method is based on the chemical sorption of Pb(II), from pH 7 buffered solutions, ...
Factorial design in the optimization of preconcentration procedure for lead determination by FAAS
(Elsevier, 2005-02-28)
The present paper proposes a preconcentration procedure for lead determination using flame atomic absorption spectrometry (FAAS). It is based on lead(II) ions extraction as brilliant cresyl blue (BCB) complex and its ...
Lead gunshot pellet ingestion and tissue lead levels in wild ducks from Argentine hunting hotspots
(Elsevier, 2014-05)
Lead poisoning in waterfowl due to ingestion of lead pellets is a long recognized worldwide problem but poorly studied in South America, particularly in Argentinean wetlands where duck hunting with lead gunshot is extensive. ...
Determination of lead in the absence of supporting electrolyte using carbon fiber ultramicroelectrode without mercury film
(Wiley-Blackwell, 1998-08-01)
The determination of lead ions directly in water, for application in analysis of samples of environmental interest, was studied by electroanalytical techniques. Linear sweep anodic stripping voltammetry with a carbon fiber ...
