  Potentially toxic metals (Pb, Fe, Mn, Cr, Cd, Zn and Cu) concentration in selected vegetables namely; lettuce (Lactuca sativa) and spinach (Spinacea oleracea) was investigated alongside their harvesting site soil samples using Atomic Absorption Spectroscopy (AAS). Some physicochemical parameters viz; pH, moisture and ash contents of the plant were also determined. The estimated metal concentrations for the vegetables ranges from 1.59-2.07 ug/g, 211-364 ug/g, 7.0-7.5 ug/g, 5.00-5.25 ug/g, 0.01 ug/g, 20.4-24.12 ug/g, 0.8-1.1 ug/g for Pb, Fe, Mn, Cr, Cd, Zn, Cu respectively. The result showed that soils in industrial site are higher in heavy metals and that vegetable grown in the industrial sites is considerably higher in metal content than those grown in normal agricultural soils. It is also observed that vegetables differ in their ability for heavy metal uptake. Highest metal concentrations were observed in lettuce and lowest in spinach.

  The Pulp of Gardenia aqualla fruit was analyzed for nutritional and anti-nutritional composition. The results obtained were moisture content (80.33%), ash (5.00%), crude lipid (1.70%), crude protein (3.85%), crude fibre (trace), available carbohydrate (89.45%) and the energy value (388.50 kcal/100 g). Elemental analyses shows that Sodium is the most abundant element (203.33 mg/100 g) while manganese is the least (0.2 mg/100 g), Lead was also detected (0.37 mg/100 g). The anti-nutritional parameters analyzed include; Phytate (26.57 mg/100 g), Soluble Oxalate (1.70 mg/100 g), Saponin (1.50 mg/100 g), Nitrate (0.38 mg/100 g) while Hydrocyanic acid content are (1.14 mg/100 g). The antinutrients to nutrients ratio indicate the bioavailability of some important minerals except in the case of [Phytate][Fe] and [Phytate][Ca] in the pulp which are found to reach the critical levels and therefore are expected to hinder Iron and Calcium bioavailability in the pulp.
