| dc.description.abstract | Biomarkers in fish are considered to be one indicator of the level of exposure and response to pollutants in a body of water. The purpose of this study was to evaluate the histopathological structure of the liver and bioaccumulation of heavy metal elements in Tilapia meat as a biomarker of environmental pollution in post coal mining ponds. Tilapia samples come from three different post-mining ponds, namely from the control pond, Godlstar pit (10 years old) and Senong pit (5 years). Heavy metal content in fish meat was analyzed using Sanning Electron Microscopy combined with an Energy Dispersive tool X-ray (SEM-EDX). The results showed that the level of accumulation of heavy metals (K, Cu, Zn) in fish samples with the highest percentage of metal elements was Cu between 1.48-1.74%; Zn between 0,80-1.17% and K between 1.58-2.43% and all of these percentages are greater than those of the control fish. Histological lesions in the liver of Tilapia, O.niloticus are in line with the accumulation of metals in meat. The levels of Cu and K in meat are more low in longer ponds, higher Zn percentage in old ponds. These results provide evidence that microanalysis of metal elements in tissue with SEM-EDX and fish liver histopathology as pollutant biomarkers can be a sensitive indicator of pollutant exposure in post-coal mine land waters. The findings of this study are expected to be used as consideration in the aspect of diagnostic methods in monitoring fish health status and quality of fish products originating from post-mining ponds. | en_US |
