Distribution of Blood Lead Levels in a Birth Cohort of New Zealanders at Age 21

Distribution of Blood Lead Levels in a Birth Cohort of New Zealanders at Age 21

Little is known about lead exposure in the general population of young adults. In this study, whole blood lead concentration (PbB) was determined in a sample of the Dunedin Multidisciplinary Health and Development Study, a well-documented birth cohort of New Zealanders aged 21 years in 1993-1994. Pb...

Zusammenfassung:Little is known about lead exposure in the general population of young adults. In this study, whole blood lead concentration (PbB) was determined in a sample of the Dunedin Multidisciplinary Health and Development Study, a well-documented birth cohort of New Zealanders aged 21 years in 1993-1994. PbB in those who consented to venipuncture at 21 years of age (n = 779; 411 males, 368 females) was compared to PbB for the same cohort at age 11 years. The PbB at age 21 ranged from 0.4 to 56 μg/dl with a geometric mean of 4.5 μg/dl (95% CI, 4.3-4.7 μg/dl). Only three individuals had a PbB above 30 μg/dl. Males had significantly higher PbB than females (geometric mean 6.0 vs. 3.2 μg/dl; p
