PESTAB. Known bat brain-to-carcass lipid relationships for DDE, DDT and dieldrin were compared for different bat species and to birds. Data were gathered from several different studies. Data from bats of three species fed DDE were plotted together and fitted to a single regression line, since covariance analysis indicated that individual species relationships were not significantly different. Other bats did not yield data which would fit this curve. The data do suggest that when bats of the same age category are examined and when analyses are performed by the same methodology, the relationships found may apply to several species. Conditions for the use of carcass lipid concentrations for diagnosis of organochlorine poisoning seem to be no more restrictive than those for use of brain concentrations. It is concluded that estimated minimum lethal concentrations in carcass lipids can be used to determine DDE, DDT or dieldrin induced mortality if they are expressed in ppm concentrations. It is suggested that bats and birds in museum collections can be examined for these organochlorine residues and pesticide induced mortality could be determined.
