Determination Of Mercury In Fish From Dopoulan River
Mercury pollution has been recognized as a potential environmental and public health problem for over forty years. The major source of exposure to mercury for humans is the ingestion of fish. The present study was conducted with the aim of determining the levels of mercury in the muscles of five fish species caught in Dopoulan River and comparing the results with the maximum tolerance levels. Forty fish samples were used for determination of mercury by graphite furnace atomic absorption spectrometry. The results revealed that the concentrations ranged from 0.53 µg/g to 1.02 µg/g, with means of 0.86 µg/kg. Concentration of mercury was lower than the threshold limits acceptable by WHO standards in all studied samples with no harm for human.
