ABSTRACT
Background: Food safety is a major public concern worldwide. During the last decades, the increasing demand for food safety has stimulated research regarding the risk associated with consumption of foodstuffs contaminated by pesticides, heavy metals and or toxins. Materials and Methods: In this study, selected heavy metals (Cd, Cr, Cu, Pb and Zn) in Green peas sold at Gwagwalada and Wuse markets in Abuja have been investigated. The samples were wet digested and the metals were analysed using Atomic Absoprtion Spectrophotometer (AAS). Results: The mean metal levels were found to be 0.75, 17.38, 0.75, 0.13, B.D.L, 34.50 µg/g for Cd, Cr, Cu Pb and Zn respectively. Zn was the highest metal found and Pb was below detection limit. The metal levels found in the study were compared with regional or international standards to determine whether these levels are within acceptable limits in foods. Conclusion: Notably, only Cd level was above the safe limits when compared with the National Agency for Food and Drug Administration and Control (NAFDAC) and World health Organization/ Food and Agriculture Organization (WHO/FAO) tolerable limits for metals in fresh vegetables.
Key words: Androgenic factors, Phytonutrient, metals, pollution, atomic absorption spectrophotometry (ASS), NAFDAC.
