Aquarium personnel observed that a number of organisms in the coral reef tank were succumbing to fungal and other diseases. It was suspected that organisms were compromised due to a common environmental stressor because many types of fish were affected. One possible stressor was the home-made painted coral decor in the tank. The coral reef decor was crumbling in several sections of the display and release of toxic agents was suspected. A water sample containing broken pieces of the decor was shipped to the lab and a TIE performed. Phase 1 TIE results indicated that toxicity to Mysidopsis bahia (mysid shrimp) was removed after EDTA addition and to some extent after cation exchange column treatment.None of the other TIE manipulations affected toxicity. Metal analyses indicated high concentrations of Zn, Cu, Ni, and Cd. To rule out the possibility of pathogens, irradiation was conducted as a novel TIE method. Results of further identification and confirmation methods using differing cation exchange column treatment. None of the other TIE manipulations affected toxicity. Metal analyses indicated high concentrations of Zn, Cu, Ni, and Cd. To rule out the possibility of pathogens, irradiation was conducted as a novel TIE method. Results of further identification and confirmation methods using differing cation exchange columns will be presented. This study demonstrates a unique application of TIE methods.
