Effects Of Pcb 126 And Ammonia, Alone And In Combination, On Green Frog (Rana Clamitans) And Leopard Frog (R. Pipiens) Hatching Success, Development, And Metamorphosis, Mariana Beatriz Jofre, Michele L. Rosenshield, William H. Karasov

Journal of the Iowa Academy of Science: JIAS

The Green Bay watershed in Wisconsin is polluted with polychlorinated biphenyls (PCBs), dioxin, heavy metals, ammonia, and over 100 organic contaminants. In this study we exposed embryos and larvae of two ranid species commonly occurring in the Green Bay ecosystem, the green frog (Rana clamitans) and the leopard frog (R. pipiens), to PCB 126 (3,3', 4,4', 5-Pentachlorobyphenil, nominal concentrations 0-50 μg/l, two control treatments: water plus 0.08% acetone as carrier for the PCB, water alone), unionized ammonia (0-2 mg/I), and mixtures of both contaminants. Exposure to PCB 126 did not cause significant mortality of embryos ...
