Abstract

Heavy metals are naturally embedded in aquatic environment, but their levels are increasing due to industrial, agricultural and mining activities. Mercury (Hg) and lead (Pb) are two of the most common toxicants that can be found in aquatic environment. Behavioural and neurological changes are associated with overexposure to Hg poisoning, while Pb might cause high blood pressure and damage to the reproductive organs. Fish is a common table food consumed by humans for protein nourishment; therefore, it is important to study heavy metal contamination in it. The aim of the present work was therefore to determine the content of Hg and Pb in milkfish (Chanos chanos Forsk) from Pampang fishponds, Makassar, Indonesia. Dithizone was used as the reagent for the qualitative analysis of Hg, while KCN was used for Pb. Quantitative analysis performed by Atomic Absorption Spectrophotometry at 253.5 nm for Hg and 283.3 nm for Pb confirmed the presence of Hg and Pb. The results showed that the average content of Hg in milkfish was 1.01 µg/g while Pb was undetected. Therefore, it could be concluded that milkfish from the Pampang fishponds were contaminated with Hg thus poses high risk for human health
