Associations of lead biomarkers and delta-aminolevulinic acid dehydratase and vitamin D receptor genotypes with hematopoietic outcomes in Korean lead workers

Blood lead levels and enzymatic biomarkers of environmental lead exposure in children in Córdoba, Argentina, after the ban of leaded gasoline

“…These results also agree with previous studies that reported that PbB levels higher than 25.0 mg/dl affected d-ALAD activity. 87,88 Similar results were obtained in studies correlating an increase in plasmatic and urinary d-ALA with PbB levels, [89][90][91] suggesting that d-ALAD activity is not a sensitive indicator of low Pb exposure. One important aspect of the d-ALAD biomarker that arises from the present study is the reduction in d-ALAD activity inhibition (61.59 + 1.15 U/L) from the value obtained by Hansen et al 24 of 38.80 + 1.10 U/L, a finding that is closely related to the decrease in PbB levels reported here compared to those obtained in that study.…”

Toxicological analysis of the risk of lead exposure in metal processing

“…The obtained results confirmed a high positive correlation between the concentration of lead in the blood and urine, and years of service of the exposed subjects (r = 0.854, p < 0.01, and r = 0.722, p < 0.01, respectively). Lee et al found a high positive correlation between blood lead levels and years of service [25], which complies with the results obtained in the present research.…”

Involvement of some low-molecular thiols in the peroxidative mechanisms of lead and ethanol action on rat liver and kidney

“…Pb concentration in the blood of the rats continuously intoxicated with 500 mg Pb/l MoniuszkoJakoniuk et al, 2003) is within a range of values noted in Pb workers (Lee et al, 2001). The blood Pb concentration, being the major indicator of exposure to this toxic metal, in the Pb and Pb + EtOH groups was 507.6 ± 28.8 and 801.7 ± 30.4 g/l, respectively.…”
