Detection of lead (Pb) heavy metal in snakeskin gourami (Trichopodus pectoralis) meat in Lake Tempe, South Sulawesi

Abstract

Abstract Trichopodus pectoralis is a type of freshwater fish member of the gourami family found in Lake Tempe. This fish can be found in the central part of Lake Tempe, known as the Pacok Balanda area. In the fisheries sector, pollution can occur in aquatic organisms due to heavy metals that pollute the waters. Meat is one part of fish that cannot be separated from the influence of heavy metal pollution, which will cause toxic effects if present in the body of a living creature and exceeds its threshold. This study aimed to determine the lead (Pb) heavy metal deposits in snakeskin gourami fish meat ( T. pectoralis ) in Lake Tempe. The research used nine T. pectoralis fish with a body length of 12 to 18.3 cm with an average of 15.32±1.75 cm and a bodyweight of 28 to 82 g with an average of 54.55±18.02 g. Measurement of Pb levels in fish meat used the Atomic Absorption Spectrophotometer test method. The results showed the presence of Pb deposits in T. pectoralis fish meat at Lake Tempe with levels ranging from 0.55 to 14.45 mg/kg. This study showed that Pb content in T. pectoralis fish meat in Lake Tempe was above the standard limit of metal contamination
