Abstract Fish intake may constitute a significant route by which humans are exposed to metals, especially people who depend on fish as source of protein Alexandrians. Therefore, this study aimed investigate the metal contents in muscles eight commonly consumed freshwater (Tilapia, Catfish, and Common Carp) marine species (Emperors, Groupers, Mackerels, Silver Pomfret, Roving Groupers) collected from local markets located Alexandria City for 1-year calendar year, 2022. Seasonal variations levels tested metals species, with differences between were recorded. Also, Cu, Zn, Fe, Co, Cd all during experiment did not exceed guideline limits, while Ni, Cr, Pb October–May, June–September, February–May 2022, respectively, exceeded permissible limits settled FAO WHO. Additionally, Mackerels Groupers had high-level Mn that European Commission. The accumulation these different relative variation accumulation, Cu was most predominant element Tilapia, Zn Fe Carp, Emperors, Co Tilapia. Consumption high Metal Pollution Index (MPI) value pose potential public health risk. On meantime, calculated values estimated daily intakes (EDI), hazard index (HI), target quotient (THQ) indicated no risk Alexandrians via consumption because they World Health Organization’s acceptable intake.

Bioaccumulation and Trophic Transfer of Heavy Metals in Marine Fish: Ecological and Ecosystem-Level Impacts

Journal of Xenobiotics, Journal Year: 2025, Volume and Issue: 15(2), P. 59 - 59

Published: April 18, 2025

Heavy metal contamination in marine ecosystems poses a critical environmental challenge, with significant implications for biodiversity, trophic dynamics, and human health. Marine fish are key bioindicators of heavy pollution because their role food webs capacity bioaccumulation transfer. This review synthesizes current knowledge on the pathways mechanisms accumulation fish, focusing factors that influence uptake, retention, tissue distribution. We explore processes governing transfer biomagnification, highlighting species-specific patterns risks posed to apex predators, including humans. Additionally, we assess ecological consequences at population, community, ecosystem levels, emphasizing its effects reproduction, community structure, interactions. By integrating recent findings, this highlights gaps suggests future research directions improve monitoring risk assessment. Given persistence bioavailability metals environments, effective control strategies sustainable fisheries management imperative mitigate long-term public health risks.
