The Cheongju Wonheung Ecological Park was constructed to help the multiplication of toads, following the beginning of the development of surrounding areas. A great number of CCA (Chromated Copper Arsenate)- treated wood structures were included in the construction around the pond and the migration passage to the nearby mountain (Guryong Mountain). Noticeable malformation, however, occurred in toad tadpoles and most of them were found to be dead after all. This study was conducted to find the cause of the incidence, focusing on the contamination of the area with heavy metals. CCA-treated wood, soil, and water samples were collected around the pond and they were analyzed for heavy metals. The results showed that teratogenic copper concentrations were highly elevated in pond water and soil samples, suggesting that CCA-treated wood may be a potential source of toad malformation.
