DETERMINATION OF HEAVY METAL LEVELS IN DRIED FISH SPECIES SOLD AT NKWO AMAENYI MARKET, AWKA ANAMBRA STATE

This study investigated the levels of heavy metals in selected dried fish species sold at Nkwo Amaenyi Market, Awka, Anambra State, Nigeria. The increasing consumption of dried fish and the potential health risks associated with heavy metal contamination necessitated this research. Samples of commonly consumed dried fish species were randomly purchased from different vendors within the market and analyzed for the presence of selected heavy metals, including lead (Pb), cadmium (Cd), chromium (Cr), mercury (Hg), and arsenic (As). Standard laboratory procedures involving sample digestion and Atomic Absorption Spectrophotometry (AAS) were employed for the determination of heavy metal concentrations. The results revealed varying concentrations of the heavy metals across the fish species examined. While some metal concentrations were within the permissible limits established by the World Health Organization (WHO) and the Food and Agriculture Organization (FAO), others showed elevated levels that may pose potential health risks to consumers when consumed over a prolonged period. The study further indicated that environmental pollution, handling practices, and methods of fish processing could contribute to heavy metal accumulation in dried fish products. The findings underscore the importance of regular monitoring and quality control measures in fish markets to ensure food safety and protect public health. The study recommends stricter regulatory enforcement, improved environmental management practices, and consumer awareness regarding the potential risks associated with contaminated fish products.
