Abstract

Silver barb (Barbonymus gonionotus) is one of the natural wealth of Indonesian waters classified as fish that are easily adaptable and widely consumed by people.The purpose of this study was to determine the effect of Cadmium (Cd) Heavy Metal Contamination in Tempe lake, Wajo Distric on Histopathology of Liver in Silver barb (Barbonymus gonionotus). The samples used were fifteen Tawes with each of the five Tawes liver samples at each station. Measurement of heavy metal content is done with Atomic Absorption Spectrofotometi (AAS) and obtained cadmium (Cd) concentrations in the liver organs of contaminated fish which were 0,04 until 0,33 mikrogram/g with an average of 0.11 plus minus 0.08 mikrogram/g. Liver organ preparations in fixation using neutral buffered formalin (NBF) 10 percent, dehydration using multilevel alcohol, embedding using paraffin, cutting with a thickness of 4 micron stained using haematoxilin eosin was then observed. Analysis of the data used is descriptive qualitative. Based on the results of observations obtained damage or histopathology that occurs in the liver that shows the existence of degeneration, hemorrhage, infiltration of inflammatory cells and necrosis. The level of damage to the tissue depends on the concentration of the metal contaminated in the fish^s organs. Most of the damage that occurred was thought to be due to exposure to heavy metals dissolved in the waters of the fish ecosystem which had passed the threshold.
