Abstract
Heavy metals are a well-known indicator of water pollutants that can present adverse impact on living things. Of this reason, the study aims to probe the bioaccumulation of mercury and cadmium in Bungo fish that live in Lake Tempe. The study tapped into purposive sampling, i.e., collecting the fish from Lake Tempe situated in Wajo, Sidrap and Soppeng. It was a three-month research, starting from June to August 2021. Samples were tested in detection work by Atomic Absorption Spectrophotometry (AAS). Results of the bioaccumulation of heavy metals in Bungo fish varied according to the sampling locations. The average bioaccumulation of mercury in Wajo, Soppeng and Sidrap was 0,066 plus minus 0,005 mg/kg- 0,048 plus minus 0,006 mg/kg- and 0,059 plus minus 0,002 mg/kg, respectively. The average bioaccumulation of cadmium in Wajo, Soppeng and Sidrap was 0,016 plus minus 0,001 mg/kg- 0,030 plus minus 0,009 mg/kg- and 0,025 plus minus 0,005 mg/kg, respectively. Accordingly, Wajo had the highest degree of mercury bioaccumulation, while Soppeng had the highest degree of cadmium bioaccumulation. In other words, Wajo was the most mercury-polluted area, and Soppeng was the most cadmium-polluted area for Bungo fish. However, the substances in both areas remained below the maximum limits for water pollution.
