【 摘 要 】

Some mineral element levels in three Nigerian Vegetables were investigated.  High levels  might cause  pollution of these vegetables thereby rendering them unsafe for consumption by the populace living in these environment. Moisture content, Iron, Manganese and Copper were determined in green Soko, Celocia argents  L; Tete, Amaranthus hybridus L; and Ewe iroko (Ugu) Telfaira occidentalis collected from four  markets (Gbangba, Kuto, Olumore and Iberekodo) in Abeokuta metropolis. Moisture content was determined by standard method while Iron was determined colourimetrically. Copper and Manganese were determined using Atomic Absorption Spectrophotometer, Perkin Elmer Corporation, Norwalk Model. % MCof the leaves ranged from 85.00% in Ugu of Gbangba to 92.48% in Soko of Kuto. The concentrations of Iron, manganese and Copper in the leaves ranged from 6.540 mgkg-1 in Tete of Kuto to 8.40 mgkg-1 in Soko of Olomore, 0.483 mgkg-1 in Ugu of Kuto and Gbangba to 8.420 mgkg-1 in Soko of Gbangba and Iberekodo, 0.041 mgkg-1 in Ugu of Kuto and Gbangba to 0.047 mgkg-1 in Soko of Iberekodo. Their observed mean values are 7.405 mgkg-1, 0.484 mgkg-1 and 0.042 mgkg-1 respectively. The levels of some elements in these vegetables were found to be below the permissible level recommended by WHO but were also found to be lower than the recommended daily dietary intake except for Manganese. Leaves of these three vegetables are recommended for consumption for the populace in this environment
