Abstract

Biomagnification refers to the process by which the concentration of certain toxic substances increases as they move up trophic levels in an ecosystem. In aquatic food chains, this phenomenon poses significant risks to the health of ecosystems and human populations dependent on these ecosystems for food and livelihood. The accumulation of persistent organic pollutants (POPs), heavy metals, and other contaminants in aquatic organisms leads to negative effects on biodiversity, species survival, and ecosystem function. This paper explores the mechanisms of biomagnification in aquatic food chains, examines its impact on aquatic organisms, and highlights the broader environmental and human health implications. Case studies on biomagnification in marine and freshwater systems are reviewed, emphasizing the effects on apex predators, such as fish-eating birds and marine mammals. The paper concludes with recommendations for monitoring and mitigating the effects of biomagnification to preserve ecosystem health and biodiversity.
