Toxic Elements and Mineral Content of Different Tissues of Endemic Edible Snails ( and ) of Montenegro.

The objective of the present study is to determine the differences between the mineral content of various organs of and , the two most abundant edible snail species in Montenegro. The bioaccumulation of 12 examined elements (zinc, manganese, copper, aluminum, cadmium, lead, nickel, iron, chromium, lithium, selenium and mercury) was determined in the hepatopancreas, albumen gland, digestive tract, reproductive system, mantle, foot and shell from three sampling sites (Biogradska Gora, Nikšić and Malesija). The examined populations of and showed a significant difference in their lithium and selenium contents.
