The leads were generally solid, but two singers stood out: Janinah Burnett, with her lushly rendered Pamina, and Kenneth Overton, with a drolly acted and finely sung Papageno.
The lead story (if it bleeds, it leads) is generally about some random shooting or some fire somewhere.
Hazardous air pollutants, which include asbestos and lead, are generally subject to strict controls at each source, a requirement intended to bring down the level of pollutants everywhere.
This broad emission band from the ZnO nanotubes/GaN film heterostructure LED is generally related to the fabrication process of nanotubes with a low temperature regime which produces a large number of defects with high diversity.
Lead was generally highly gastric bioaccessible, with 39 66% of the total lead solubilized in an hour from 9 of 12 samples analyzed (Table 3, Figure 3).
Tibia lead, a measure of cortical bone lead, is generally a less important source of blood lead levels than is lead in trabecular bone, but is a good estimate of cumulative lead dose (Hu et al. 1998).
Second, the standards considered the level of lead in whole blood to be the key lead bio-marker and, although not explicitly discussed, blood lead was generally used only as a measure of relatively recent dose.
Lead and lead compounds are generally toxic pollutants (EPA safe limit is 0.015 mg/L (Obuseng et al. 2012).
Third, we used convulsions and deaths as clinical indicators for lead poisoning because symptoms of lead poisoning are generally nonspecific, and blood lead testing was unavailable at the beginning of the outbreak when the majority of affected children died.
Several investigators report that umbilical cord blood lead concentrations are generally lower than maternal blood lead concentrations (Chuang et al. 2001; Harville et al. 2005; Rothenberg et al. 1996).
