  • Title: [Chromosome analysis in professional subjects exposed to lead contamination].
    Author: Garza-Chapa R, Leal-Garza CH, Molina-Ballesteros G.
    Journal: Arch Invest Med (Mex); 1977; 8(1):11-20. PubMed ID: 849093.
    Abstract:
    Chromosomes were analyzed in cultured lymphocytes of 44 male workers from a lead oxide factory, and from a control group of 15 nonexposed individuals. Lead concentration in blood ranged from 30 to 75 mug/100 ml in exposed subjects and from 15 to 35 mug/10 ml in controls. Length of exposure to lead ranged from one month to 11 years eight months. In subjects occupationally exposed to lead, a significant increase in chromatid and chromosome aberrations was found. The frequency of such findings parallels exposure time to lead.
