4.0 Conclusion
Relatively high levels of PTE (As, Cd, Cr, Cu, Mn, Ni, Pb, and Zn) were observed in the vegetables studied, with the most of the values obtained higher than the recommended tolerable safe limits established by FAO/ WHO. The highest level of As, Cr and Ni were found in Pumpkin leaves, Mn and Cd in Okro leaves, Pb in Spinach, however Zn was found to be high in all the vegetables. The trend of
