title: SCE analysis in children exposed to lead emission from a smelting plant.
abstract: The frequency and location of SCE were evaluated in lymphocytes from peripheral blood cultures of 19 children living in a widely contaminated area and showing an increased absorption of lead. In the comparison between the exposed children and a control group living in an uncontaminated area, no significant differences were found in the mean values of SCE frequencies. The distributions of the SCE between chromosomes were proportional to chromosome length in both groups.
