Trace elements and omega-3 fatty acids of black sea (Bulgaria) bivalve species Mytilus galloprovincialis, Chamelea gallina and Donax trunculus. Human health risk

Abstract The study aimed to evaluate trace elements (Cd, Cr, Cu, Fe, Ni, Pb and Zn) concentrations and fatty acids of three Black Sea bivalve species - Donax trunculus, Mytilus galloprovincialis and Chamelea gallina as well as human health risk and benefit-risk ratio based on n-3 LC-PUFA vs. toxic/essential elements. The results showed variations in the element concentrations among the analysed species. D. trunculus generally contained higher levels of the essential elements Cu and Zn, while C. gallina – higher Cr and Fe. Toxic elements content did not exceed the international standards for mollusks. D. trunculus and C. gallina were better dietary sources of n-3 LC-PUFA, with approximately two-fold higher EPA + DHA content than M. galloprovincialis. Health risks for most toxic and essential elements exposed from bivalve consumption were safe based on THQ, HI and TR indices. The benefit-risk ratio indicated that studied species are safe for human consumption, except one case. Graphical Abstract
