The aim of the present work is to broaden our knowledge on the variability of metals and metalloid concentration levels in surface sediments, macroalgae and mollusc. Accordingly, As, Co, Cr, Cu, Mn, Mo, Ni, Pb, and Zn levels in surface sediments, marine macroalgae species (Ulva intestinalis and Ceramium rubrum) and mollusk (mussel Mytilus galloprovincialis) collected from nine stations along the Sürmene Bay, Black Sea, Turkey, have been investigated using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Hence, higher concentration levels of As, Cu, Mn, Pb and Zn have been recorded in the sediments and macroalgae collected from the harbor area, largely exceeding those recorded in previous studies carried out in the Turkish Black Sea. Consequently, sampled sediments from such area have revealed the highest Contamination Factor (Cf) values as well as the highest Contamination Degree (CD) levels, signaling higher ecological risks. Furthermore, U. intestinalis has shown higher accumulation capacity than C. rubrum and M. galloprovincialis. The Target Hazard Quotient (THQ) and the Hazard Index (HI) have been carried out in order to evaluate the non-carcinogenic health risks posed by metals/metalloid via M. galloprovincialis consumption, revealing values below 1 for all sampling sites, indicating thus no adverse effects on human health.

本工作的目的是拓宽我们对表面沉积物，大型藻类和软体动物中金属和准金属浓度水平变异性的认识。因此，表层沉积物中As，Co，Cr，Cu，Mn，Mo，Ni，Pb和Zn的含量，海洋大型藻类（Ulva intestinalis和Cerramium rubrum）和软体动物（贻贝Mytilus galloprovincialis）使用电感耦合等离子体质谱法（ICP-MS）对从土耳其黑海苏尔梅内湾沿线9个站收集的）进行了研究。因此，从海港地区收集的沉积物和大型藻类中已记录到较高的砷，铜，锰，铅和锌浓度水平，大大超过了之前在土耳其黑海进行的研究所记录的浓度。因此，从该区域取样的沉积物显示出最高的污染因子（Cf）值和最高的污染度（CD）水平，表明较高的生态风险。此外，与小球藻和鸡血单胞菌相比，小肠蟹的蓄积能力更高。。为了评估金属/准金属通过鸡传染性支原体的摄入所造成的非致癌健康风险，已经进行了目标危险度（THQ）和危险指数（HI）的分析，所有采样点的数值均低于1，这表明对人体健康无不利影响。
