Resumo

Northern bobwhite (Colinus virginianus) and scaled quail (Callipepla squamata) from the Rolling Plains ecoregion in Texas and Oklahoma were evaluated for organochlorine pesticides, Pb, and Hg. Of all organochlorine pesticides analyzed, only p,p'-dichlorodiphenyldichloroethylene (p,p'-DDE) and p,p'-dichlorodiphenyldichloroethane (p,p'-DDD) were found in a few composite liver samples. Similarly, a small fraction of tissue samples had detectable levels of Hg (liver and breast) or Pb exceeding background concentrations (femur). Lead concentrations in a few individuals fell within the range associated with moderate toxicity.
