ASSESSMENT OF THE LEVELS OF COPPER, CHROMIUM, MANGANESE, LEAD, ZINC, CADMIUM, and IRON

Taking safety into account, the levels of Cu, Cr, Mn, Pb, Zn, Cd, and Fe in Bitter leaves and Scent leaves have been assessed. This study involves the collection of fresh vegetable samples from Uselu market, Edo State, Nigeria. The samples were prepared using stander methods to quantify the concentrations of heavy metals present. The analytical finish was done by Atomic Absorption Spectrophotometer (AAS) model Buck Scientific VGP210 to obtain accurate measurements of heavy metal content in Scent leaves and Bitter leaves. Analytical data available shows a pattern of Cu 0.20mg/kg, Cr 0.10mg/kg, Mn 7.50mg/kg, Pb 0.00mg/kg, Zn 5.15mg/kg, Cd 0.05mg/kg, Fe 6.50mg/kg for Scent leaves and Cu 0.20mg/kg, Cr 0.15mg/kg, Mn 5.00mg/kg, Pb 0.05mg/kg, Zn 4.85mg/kg, Cd 0.05mg/kg, Fe 4.50mg/kg
for Bitter leaves. These data were compared to World Health Organization (WHO) and National Agency for Food, Drugs Administration and Control. The results showed that the levels complied with regulatory standards. The findings of this research will provide valuable insights into the levels of these selected heavy metals in Scent leaves and Bitter leaves, allowing for a comprehensive assessment of potential risks associated with their consumption. Furthermore, this study will contribute to enhancing public awareness about food safety and help formulate recommendations to mitigate heavy metals contamination in vegetables.
