Effect of Pb-Polluted soil on soybean growth and associated toxicological risk
(Springer, 2021-10)
Glycine max (L.) Merr. (soybean) has been mentioned as a potential accumulator of hazardous metals, such as Pb. The main route of human exposure to heavy metals is consumption. This study evaluates Pb accumulation in soybean ...
Mecanismos reacionais e os processos de carga e descarga no caso de eletrodos planos de Pb em ácido sulfúrico e formação de eletrodos planos de PbO2 partindo de eletrodos de Pb
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Química, 2007-10-04)
Two systems that form the basis of the lead-acid batteries were studied. The first system was the lead/sulfuric acid (Pb/H2SO4) interface. This interface is equivalent to negative electrode of lead acid batteries. The ...

Estudos teóricos de propriedades eletrônicas e estruturais do PbO e PbO2
(Universidade Estadual Paulista (Unesp), 2015-02-26)
PbO has two main allotropic phases: a-PbO, massicot type tetragonal structure belonging to space group P42/mnm (129), with cell constants a = 0.3975 nm and c = 0.5022 nm and B-PbO, litharge type orthorhombic structure ...
Preparação e caracterização de filmes de PbO2 sobre diferentes substratos e MnO2 sobre fibra de carbono para aplicação no tratamento eletroquímico de efluentes simulados
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2008-02-29)
PbO2 films were grown on different substrates (Ti-Pt, ADE, FC and Pb), at constant current density of 20 mA cm-2, using two methodologies: electrodepositon from 0.1 mol L-1 Pb(NO3)2, 1.7 mmol L-1 LSS and 0.1 mol L-1 HNO3 ...
Vitamin D receptor haplotypes affect lead levels during pregnancy
(ELSEVIER SCIENCE BV, 2010)
Pregnant women are particularly susceptible to toxic effects associated with lead (Pb) exposure. Pb accumulates in bone tissue and is rapidly mobilized from bones during pregnancy, thus resulting in fetal contamination. ...
Assessment of how pregnancy modifies plasma lead and plasma/whole blood lead ratio in ALAD 1-1 genotype women
(BLACKWELL PUBLISHING, 2008)
Pregnant women are one of the most sensitive populations to the toxic effects associated with lead (Pb) exposure. These effects are primarily associated with plasma Pb (Pb-P), which reflects the most rapidly exchangeable ...
Isotopic and elemental determination of lead in particulate matter in the cities of Goiânia (GO) and Rio Claro (SP) using ICP-MS technique
(Universidade Estadual Paulista (Unesp), 2016-09-13)
The toxic metal lead (Pb) can be harmful to human health in various manners, but is also considered as a distinguished tracer of environmental pollution, since the relative abundance of its four stable isotopes with the ...
