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 - and 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. generally contained higher levels of the essential elements Cu and Zn, while - higher Cr and Fe. Toxic elements content did not exceed the international standards for mollusks. and were better dietary sources of n-3 LC-PUFA, with approximately two-fold higher EPA + DHA content than . 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.
该研究旨在评估三种黑海双壳贝类物种中的微量元素（镉、铬、铜、铁、镍、铅和锌）浓度以及脂肪酸，并基于n-3长链多不饱和脂肪酸与有毒/必需元素评估人类健康风险和效益风险比。结果表明，分析的物种之间元素浓度存在差异。一般来说，紫贻贝中必需元素铜和锌的含量较高，而翡翠贻贝中铬和铁的含量较高。有毒元素含量未超过软体动物的国际标准。紫贻贝和翡翠贻贝是n-3长链多不饱和脂肪酸更好的膳食来源，其二十碳五烯酸（EPA）+二十二碳六烯酸（DHA）含量比欧洲平牡蛎高约两倍。根据危害商数（THQ）、健康指数（HI）和毒性风险指数（TR），食用双壳贝类所接触的大多数有毒和必需元素的健康风险是安全的。效益风险比表明，除了一个案例外，所研究的物种对人类食用是安全的。
