Heavy metals (HMs) contamination significantly threatens plants, animals, aquatic ecosystems, and public health. HMs’ accumulation in environments has become a serious environmental issue due to their high stability, bioaccumulation, biomagnification properties. These enter ecosystems through both natural sources and/or human activities. The toxicity of HMs poses threat the aquaculture sector’s sustainability by negatively affecting fish growth, reproduction, overall physiology. Exposure various forms can cause damage, which may affect health direct poisoning symptoms or other adverse effects. One such effect is increased production reactive oxygen species (ROS), crucial metabolites that modulate functions pathogenic organisms lead oxidative stress. This, turn, contribute onset exacerbation numerous diseases threaten This review article examines potential organisms, impact this on generation ROS, implications for resulting from consumption contaminated products.

This study investigates seasonal and gender-related variations in some metal (Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, Zn) accumulation black scorpionfish (Scorpaena porcus) from Izmir Bay (Aegean Sea, Türkiye) assesses the associated human health risks. Samples, collected across four seasons 2023 to 2024, were analyzed for element concentrations using inductively coupled plasma mass spectrometry (ICP-MS). Health risks calculated several models, including estimated weekly intake (EWI), target hazard quotient (THQ), total THQ (∑THQ), carcinogenic risk (CR), Se benefit value (HBVSe), Metal Pollution Index (MPI). The results indicate that consumption of poses potential risks, primarily due manganese (Mn), lead (Pb), mercury (Hg), which exceeded international permissible legal limits. Gender-based differences observed, with males showing higher (p > 0.05); however, these not statistically significant. In contrast, significant sex-based identified specifically cadmium (Cd), exhibiting a meaningful difference < 0.05). Seasonal also apparent (CR) analyses revealed chromium (Cr) nickel (Ni) levels surpassed thresholds. Furthermore, MPI values provided additional insights into overall pollution fish. These findings underscore critical importance monitoring pollution, revising fishery management strategies, managing fish safeguard public health.

Introduction This study aimed to measure the concentration of toxic heavy metals in wastewater samples and Nile tilapia ( Oreochromis niloticus ) species inhabiting (waste stabilization ponds) evaluate their safety as a food source southwestern Ethiopia. For this purpose, like lead (Pb), cadmium (Cd), arsenic (As), mercury (Hg) fish tissues (muscle, gill, liver) were independently examined. Methods A laboratory-based cross-sectional was performed ascertain levels Pb, Cd, As, Hg O. samples. Heavy metal analyzed by microplasma atomic emission spectrometry (Agilent 4210 MP-AES) hydrogen-generated absorption (HGAAS, novAA 400P, Germany). Results concentrations measured following decreasing order (µg L −1 ): Cd &gt; Pb As facultative maturation ponds, with (27.66 µg having highest (0.349 lowest concentration. Among detected samples, showed statistically significant difference between sampling points p = 0.023). The maximum for (0.35 mg kg (0.24 muscle tissue . value (0.02 edible muscles exceeded FAO/WHO permissible limit (MPL 0.01) human consumption. carcinogenic non-carcinogenic health risks consuming due trace relatively low posed fewer potential threats health. According finding, children more susceptible exposure than adults. Conclusion Due high quantities these harmful metals, from oxidation ponds should not be used fishing avoid bioaccumulation. target risk (TR) hazard quotient (THQ) indicated that all below safe threshold. research will provide baseline monitoring various aquatic creatures future artificial habitats regulatory considerations.

The increasing exposure of lentic water bodies to pollutants and the ability aquatic organisms bioaccumulate heavy metals in its edible body parts has raised concerns on food safety animals harvested from them. This study investigated distribution organs C. gariepinus T. zillii Ikpoba reservoir evaluated potential human health risk associated with their consumption. Fish samples Clarias Tilapia were collected for a period six months (January 2019 June 2019) using drag net assistance artisanal fishermen. properly identified metal content gills, liver muscles determined atomic absorption spectrophotometer. results showed that had higher mean concentration metalloids than all examined. order accumulation gills was Fe > Zn Mg Cu Pb Cd, while both fish species Cd. Human assessment indicated no significant adults (HI < 1), whereas children predisposed non-carcinogenic effect 1). Carcinogenic values Cd did not exceed acceptable carcinogenic value humans. integrated (ICR) classified consumption as low – medium (Grade III). shown selected is safe children. Also, along head portion should be discouraged reduce toxicity. continuous monitoring activities within watershed mitigate pollution recommended.
