title: Chromosomal aberrations in the cotton rat, Sigmodon hispidus, exposed to hazardous waste.
abstract: The study of chromosome damage in rodents living on hazardous-waste sites may provide evidence of important biological consequences of chronic exposure to toxic chemical wastes. This study compared bone-marrow cells of animals (Sigmodon hispidus) taken from two superfund waste-disposal sites with those from an uncontaminated site and demonstrated that both populations exposed to hazardous wastes had significantly more structural and numerical aberrations than the control population.
