background: hematological effects and digestive and neuro-psychological signs and symptoms are some manifestations of lead toxicity. however, there are conflicting reports of their prevalence among lead exposed workers and their relationship with blood lead levels (bll). this case- control study assessed the relationship between bll and hematological indexes and digestive (abdominal colic, iron...

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.
