Description:
Umbilical cord blood specimens from 11,837 births between April 1979 and April 1981 have been analyzed for lead by anodic stripping voltammetry. The mean was 6.56 +/- 3.19 (standard deviation) micrograms per deciliter of blood, and the range was 0.0 to 37.0 micrograms per deciliter. The mean decreased annually by 0.77 +/- 0.03 microgram per deciliter, about 11 percent. Lead concentrations were higher in infants born in summer than in infants born in winter (7.17 versus 5.99, probability less than .001). A Fourier model of the data is presented, and possible reasons for the decline are discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rabinowitz, M B -- Needleman, H L -- New York, N.Y. -- Science. 1982 Jun 25;216(4553):1429-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7089532" target="_blank"〉PubMed〈/a〉
