The influence of the sintering system on PMN properties
(2003-03-15)
PMN powder samples with PbO excess of 0, 1,2 and 3% were submitted to the pressing and sintering at 1200°C for 4h with a heating rate of 3°C/min. A new sintering system, developed at our laboratories, was used. It allows ...
Lead exposure in an urban community: Investigation of risk factors and assessment of the impact of lead abatement measures
(Academic Press Inc Elsevier ScienceSan DiegoEUA, 2007)
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 ...
A fast method for the determination of lead in honey samples using stabilizer-free silver nanoparticles
(2018-01-15)
A sensitive, rapid and robust method based on the use of stabilizer-free silver nanoparticles was developed for lead detection in honey. Silver nanoparticles were synthesized without the presence of any stabilizers using ...

Metalloproteinase inhibition protects against reductions in circulating adrenomedullin during lead-induced acute hypertension
(Wiley-Blackwell, 2015-06-01)
Intoxication with lead (Pb) results in increased blood pressure by mechanisms involving matrix metalloproteinases (MMPs). Recent findings have revealed that MMP type two (MMP-2) seems to cleave vasoactive peptides. This ...
A plateau detected in lead accumulation in subsurface deciduous enamel from individuals exposed to lead may be useful to identify children and regions exposed to higher levels of lead
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
In a previous study, we showed 4 times more lead in surface deciduous enamel (1.9-5.9 mu m) of a notoriously contaminated area (Bauru, Sao Paulo State, Brazil) in comparison to samples from a region with no lead contamination ...
Direct amorphous-to-cubic perovskite phase transformation for lead titanate
(2000-01-01)
The phase evolution of lead titanate processed by the polymeric precursor method was investigated by thermal analysis, X-ray diffraction, and high-resolution transmission electron microscopy. The results showed that the ...
Lead in saliva from lead-exposed and unexposed children
(ELSEVIER SCIENCE BV, 2009)
Introduction: Whole blood is used for diagnosis of lead exposure. A non-invasive method to obtain samples for the biomonitoring of lead contamination has become a necessity. This study 1) compares the lead content in whole ...
