Abstract

Tempe, Sidenreng and Lapompakka lakes are having potential fisheries. One species mostly consumed is Tawes, Barbonymus gonionotus. Household waste, industrial and agricultural activities around the lake are suspected to be the source of metal pollution to these lakes and their organism, particulary of lead (Pb) and cadmium (Cd). This study aim at analyzing the lead (Pb) and cadmium (Cd) concentration in Tawes, Barbonymus gonionotus and to determine whether this Tawes species is still safe to be consumed. Total samples collected were 54 fish. The Pb and Cd concentration were determine from the fish flesh and analyzed using the Atomic Absorption Spectrophotometry (AAS) method and presented descriptively. The results showed that the concentrations of Pb and Cd in this species of all three lakes were not detected. Based on the quality standards for metal contamination of Pb and Cd in the fish and its processed products according to SNI (2011), the concentrations of Pb and Cd in the three lakes have not exceeded the standard, meaning that Tawes fish is still suitable for consumption.
