Presence of heavy metal pollutants indicates an alarming situation that disrupts marine trophic dynamics, presenting substantial threats to fish populations and ultimately affecting human societies that depend on these aquatic resources for sustainable nutrition.
The present study focused on three fish species from Chennai (Tamil Nadu, India), namely , and . Heavy metal profiling was conducted on organs such as liver, gills, and muscle tissue. ICP-MS was utilized to determine the concentrations of heavy metals.
Upon analysis of Arsenic (As), Cadmium (Cd), Chromium (Cr), Mercury (Hg), Lead (Pb), Strontium (Sr), and Vanadium (V), the concentration ranges (dry weight) were observed as 0.044-0.096 μg/kg, 0.696-0.778 μg/kg, 5.259-12.399 μg/kg, 0.020-0.660 μg/kg, 15.400-17.649 μg/kg, 1.068-15.200 μg/kg, and 0.150-1.208 μg/kg, respectively, across the three fish species. The muscle tissues of exhibited the highest heavy metal contamination, particularly due to its elevated Chromium (Cr) concentration of 12.399 μg/kg.
recorded the highest Hazard Index (HI) in both children (0.238) and adults (0.136). However, the HQ and HI values were < 1, suggesting that consumption of these fish species remains within a safe limit regarding heavy metal contamination. These findings underscore the need for strict monitoring and regulatory measures to reduce further heavy metal contamination in seafood.
重金属污染物的存在表明了一种令人担忧的情况，它扰乱了海洋营养动态，对鱼类种群构成重大威胁，并最终影响依赖这些水产资源获取可持续营养的人类社会。
本研究聚焦于来自金奈（印度泰米尔纳德邦）的三种鱼类，即 、 和 。对肝脏、鳃和肌肉组织等器官进行了重金属剖析。利用电感耦合等离子体质谱法（ICP-MS）测定重金属浓度。
在分析砷（As）、镉（Cd）、铬（Cr）、汞（Hg）、铅（Pb）、锶（Sr）和钒（V）时，观察到三种鱼类的浓度范围（干重）分别为0.044 - 0.096微克/千克、0.696 - 0.778微克/千克、5.259 - 12.399微克/千克、0.020 - 0.660微克/千克、15.400 - 17.649微克/千克、1.068 - 15.200微克/千克和0.150 - 1.208微克/千克。 的肌肉组织重金属污染最高，尤其是其铬（Cr）浓度高达12.399微克/千克。
在儿童（0.238）和成人（0.136）中均记录到最高的危害指数（HI）。然而，危害商数（HQ）和危害指数（HI）值均<1，这表明食用这些鱼类在重金属污染方面仍处于安全限度内。这些发现强调了需要采取严格的监测和监管措施，以减少海鲜中进一步的重金属污染。
