EVALUATION OF MINERAL (FE, CA AND ZN) AND HEAVY METALS (MN AND PB) COMPOSITION OF PROCESSED CASSAVA PRODUCT (FUFU) SOURCED FROM DIFFERENT MARKETS IN PORT HARCOURT METROPOLIS
Abstract
This study was carried out to assess the mineral composition and potential heavy metal contamination of fermented cassava fufu sourced from four key markets in Port Harcourt Metropolis: Choba, Borokiri, Oilmill, and Mile 3. The samples were collected over 4 weeks (n=4) and analyzed using atomic absorption spectroscopy. Iron, calcium and zinc was analyzed for mineral composition while lead and manganese was analyzed for heavy metals. Further statistical analysis was done to compare the mineral and heavy metal levels across markets and assess potential correlations with environmental factors. Results revealed some variations in the 4 markets for the samples, (5.764 - 9.666 mg/kg) for Iron, (6.772-12.354 mg/kg) for Calcium, (10.323 - 14.960 mg/kg) for Zinc, (0.730 - 2.164 mg/kg) for Manganese and (0.270 - 0.978 mg/kg) for Lead. Some values exceeding the permissible level, some not up to while others were within the standardized limit. Factors influencing mineral and heavy metal content are likely cassava variety, soil conditions, and processing methods. These findings highlight the need for further research to understand the variability and influencing factors, and for targeted interventions to optimize mineral content in fufu and reduce heavy metal content for a balanced and healthy diet for the population of Port Harcourt Metropolis.
