mehg and total mercury concentrations were determined in the muscle tissues of four fish species (cyprinus carpio, rutilus frisii, carassius auratus and esox lucius) from anzali wetland (guilan, iran). fish with the highest amount of mehg was selected to determine the thermodynamic parameters of mehg extraction. the extractions process was performed in the range of temperatures 331.15 to 367.15...
