Abstract
Heavy metal contamination poses significant ecological and health risks in aquatic ecosystems due to its persistence and bioaccumulation potential. This study assesses heavy metal contamination in Brycinus macrolepidotus from the Ovia River, Nigeria, using non-invasive techniques. Iron (Fe), zinc (Zn), copper (Cu), lead (Pb), and cadmium (Cd) levels were examined in muscle tissues, caudal fins, and scales. The research begins with an in-depth background study emphasizing the
environmental and health implications of heavy metal contamination. Non-invasive techniques are prioritized to accurately assess contamination levels while minimizing harm to fish populations. Ovia River, chosen for its freshwater ecosystem supporting diverse aquatic life and human activities, serves as the study area, with sampling locations representing both upstream and downstream conditions affected by various human activities. Sample collection involved careful handling of Brycinus macrolepidotus specimens to preserve their physiological state. Noninvasive methods collected muscle tissue, caudal fin clips, and scales for heavy metal analysis, ensuring minimal harm to the fish. Results reveal varying heavy metal concentrations, predominantly iron and zinc, in different fish tissues. Non-invasive techniques effectively assessed contamination levels, providing insights crucial for environmental monitoring and conservation efforts.
