Bivalve are exposed to a wide range of contaminants, some of which may be toxic to human health. The aim of this study was to detect essential and non-essential elements such as Na, Ca, Mg, Cr, Mn, Fe, Ni, Cu, Zn, As, Cd, Pb, Hg, Be and Co in water, sediments, and and from Faro Lake. It is a lake of marine origin located on the northern coast of Messina (Sicily), where shellfish farming has been practiced for many years. Metals were analysed by a single quadrupole inductively coupled plasma mass spectrometer (ICP-MS), except for Hg, which was quantified using a direct mercury analyser (DMA-80). The study evaluated the nutritional intake of elements through the ingestion of clams and mussels and the potential health risks to consumers. The lead levels found in were below the LOQ, while in the concentrations were below the limit indicated by European Regulation 915/2023. Statistical analysis was carried out on and samples using SPSS 27 and the data showed highly significant differences between the two species ( < 0.001). Cadmium (Cd) and mercury (Hg) concentrations were also below the legal limit in all samples analyzed. This study has shown that clams and mussels are a source of sodium (Na) with a Recommended Dietary Allowance (RDA) of 36% in and 77% in . The percentages obtained for calcium (Ca) and magnesium (Mg) were 17%-19% and 18%-8%, respectively. The RDA of chromium (Cr) was of 191% for and of 405% for The Fe percentages were 92% and 169% for and , respectively. The concentrations of the other metals observed in the two bivalve species of Lake Faro were generally lower than the Tolerable Weekly Intake (TWI) values estimated as a risk to human health.
双壳贝类会接触到多种污染物，其中一些可能对人体健康有毒。本研究的目的是检测法罗湖水中、沉积物以及双壳贝类中的钠（Na）、钙（Ca）、镁（Mg）、铬（Cr）、锰（Mn）、铁（Fe）、镍（Ni）、铜（Cu）、锌（Zn）、砷（As）、镉（Cd）、铅（Pb）、汞（Hg）、铍（Be）和钴（Co）等必需和非必需元素。它是一个起源于海洋的湖泊，位于墨西拿（西西里岛）的北部海岸，那里的贝类养殖已经开展多年。除汞（Hg）外，金属通过单四极杆电感耦合等离子体质谱仪（ICP-MS）进行分析，汞使用直接测汞仪（DMA-80）进行定量。该研究评估了通过食用蛤蜊和贻贝摄入元素的营养情况以及对消费者的潜在健康风险。在[具体样本1]中发现的铅含量低于定量限，而在[具体样本2]中的浓度低于欧洲法规915/2023规定的限值。使用SPSS 27对[具体样本1]和[具体样本2]进行统计分析，数据显示这两个物种之间存在极显著差异（P<0.001）。在所有分析样本中，镉（Cd）和汞（Hg）的浓度也低于法定限值。本研究表明，蛤蜊和贻贝是钠（Na）的来源之一，在[具体样本1]中的膳食推荐摄入量（RDA）为36%，在[具体样本2]中为77%。钙（Ca）和镁（Mg）的百分比分别为17%-19%和18%-8%。铬（Cr）的RDA在[具体样本1]中为191%，在[具体样本2]中为405%。铁（Fe）的百分比在[具体样本1]和[具体样本2]中分别为92%和169%。在法罗湖的两种双壳贝类中观察到的其他金属浓度通常低于估计对人体健康有风险的每周耐受摄入量（TWI）值。
