OBJECTIVE Blood lead (B-Pb), one of the most used toxicological biomarker all kind, has serious limitations. Thus, the objective is to evaluate whether plasma lead (P-Pb) is more adequate. METHODS A long-term follow-up study of five cases of lead poisoning. P-Pb was analysed by inductively coupled plasma mass spectrometry. Kinetics after end of exposure was modelled. RESULTS P-Pb at severe ...

In May 2012, the CDC adopted a new sliding scale reference value for childhood lead poisoning, reducing the former 10 μg/dL benchmark by half. Using Massachusetts (MA) as a model state, we estimated the change in the population of 9-47 month-olds at risk for lead poisoning. We then examined the impact of the 5 µg/dL reference value on the demographic characteristics of lead risk in MA communiti...

The heterogeneity of lead isotope ratios white paints within individual paintings is evaluated. analyses five different 17th-century Dutch paintings, sampled in locations, identifies the presence isotopic a single painting. Pure pigment form cones 16th-century Venetian white, contrast, was found to be isotopically homogeneous. study evaluates origins increased evolution from pure artwork.
