由于人类可能面临的健康问题,海洋生物中的微量元素生物积累是一个日益严重的国际问题。分析了沉积物中的13种微量元素,水,和红海鱼的肌肉组织。此外,平均每日摄入量(EDI),癌症风险(CR),危险指数(HI),在评估与消费相关的任何可能的健康问题时,已经考虑了这些元素的目标危险商(THQ)。所有物种在肌肉中呈现了所有分析元素的可量化值(砷(As),铅(Pb),铜(Cu),铝(Al),硼(B),铁(Fe),钡(Ba),锰(Mn),镍(Ni),镉(Cd),铬(Cr),锌(Zn),和汞(Hg),除Cd和Hg外,铁和锌是所有物种中积累最多的元素。相反,在水样中,除了铝,大多数元素都没有删除,硼,铁,和锌。所有红海鱼,然而,有锌的浓度,Ni,Fe,Cu,Mn低于允许的上限,尽管大多数物种的砷含量较高,Cr,和铅(0.48±0.83-5.10±0.79,1.97±0.46-5.25±0.67和2.12±1.01-6.83±0.93µg/g,分别)。研究的红海鱼显示Mn的污染程度(CD),Cu,Fe,Ni,Zn,铅≤1,表明污染最小,As和Cr表现出较高的污染程度。然而,污染指数值(MPI-元素)可以按照升序表示:Lethrinusramak
Trace element bioaccumulation in marine organisms is a rising international issue due to possible health concerns for humans. Thirteen trace elements were analyzed in the sediment, water, and muscular tissue of Red Sea fish. Additionally, the average daily intake (EDI), the cancer risk (CR), the hazard index (HI), and the target hazard quotient (THQ) of those elements have been taken into consideration when evaluating any possible health concerns related to their consumption. All species presented quantifiable values in muscle for all the analyzed elements (arsenic (As), lead (Pb), copper (Cu), aluminum (Al), boron (B), iron (Fe), barium (Ba), manganese (Mn), nickel (Ni), cadmium (Cd), chromium (Cr), zinc (Zn), and mercury (Hg), except for Cd and Hg, being Fe and Zn the most accumulated elements in all species. Conversely, in water samples, most elements were undeleted except for aluminum, boron, iron, and zinc. All Red Sea fish, however, had concentrations of Zn, Ni, Fe, Cu, and Mn below the upper limit allowed, although most species had higher levels of As, Cr, and Pb (0.48 ± 0.83-5.10 ± 0.79, 1.97 ± 0.46-5.25 ± 0.67 and 2.12 ± 1.01-6.83 ± 0.93 µg/g, respectively).The studied Red Sea fish showed contamination degrees (CD) of Mn, Cu, Fe, Ni, Zn, and Pb were ≤ 1, indicating minimal contamination, with As and Cr showing higher contamination degrees. However, the pollution index values (MPI-elements) can be represented according to ascending order: Lethrinus ramak < Cephalopholis hemistiktos < Pagellus affinis < Trachurus japonicus < Cheilinus lunulatus < Siganus luridus < Parupeneus forsskali < Caesio suevica. The study found that edible tissues are safe for human consumption, with HI values for children and adults less than ten, indicating negligible non-cancer hazards. However, fish consumption presents health risks due to chromium, lead, and arsenic, with THQ values several times greater than 1, and CR-Ni, CR-Cr, and CR-As values exceeding the acceptable 10-4 value in all studied species. This study provides critical insights into trace element contamination in marine fish species, highlighting the need for ongoing monitoring and proactive measures to ensure safe marine fish consumption in the Aqaba Gulf.
