Distribution of mercury and methyl mercury in tissues of transplanted mussels

Total mercury and methyl mercury concentrations were determined in whole soft tissue, gills and digestive gland of mussels from the Kaštela Bay, which is polluted with inorganic mercury. Concentrations of total mercury in the digestive gland were 1.5-5.5 times higher than in the whole soft tissue and gills, while concentrations of MeHg were similar in all analyzed tissues. The percentage of methyl mercury in the digestive gland (4-11 %) was lower in comparison to the gills (12-25 %) and the whole soft tissue (13-27 %). A negative correlation was observed between the total mercury concentration in the tissues and the percentage of methyl mercury.
