title: Use of bullfrogs (Rana catesbeiana) as biological markers for 2,3,7,8-tetrachlorodibenzo-p-dioxin contamination in the environment.
abstract: Adult bullfrogs were collected along the Rockey Branch Creek in Arkansas. This area is known to be contaminated with 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD). The levels of 2,3,7,8-TCDD found in livers from these bullfrogs ranged from 0.64 to 48 ppb. These results suggest the utility of bullfrogs as a biological marker for 2,3,7,8-TCDD in the environment.
