Content of Trace Elements in Tissues of Gastropod Mollusks of the Family Buccinidae (Gastropoda) off the Coasts of South-Eastern Sakhalin (the Sea of Okhotsk)

Abstract

The content of Pb, Cd, Cu, Cr, Mn, Ni, Fe, and As in the muscle, mantle, and digestive glands of the gastropod mollusks Neptunea excelsior, N. behringiana, N. multistriata, and N. varicifera, as well as Buccinum verkruezeni, living near the coasts of the South-Eastern Sakhalin has been estimated. Representatives of the ge-nera Neptunea and Buccinum showed some differences in the ranges of variation and series of value sequences of trace element concentrations in the muscle. Exceeding the hygienic standard for the content of As in the hepatopancreas was found in all the studied mollusks, and in the muscle – in all, except for N. behringiana. The maximum permissible level of Cd concentration was exceeded in the hepatopancreas of N. multistriata.
