The purpose of the study was to evaluate some proximate compositions and health risk of heavy metal uptake by vegetables grown at a waste-water irrigated sites in FCT, Abuja. The study was carried in dry seasons between 2015 and 2017. Two different types of vegetable samples (Lagos Spinach- Celosia argentea and African Egg-plant- Solanum macrocarpon) were collected simultaneously from three irrigated farm sites. Heavy metal levels were quantified using Atomic Absorption Spectrophotometer (AAS). Other parameters were determined using standard methods. The levels of heavy metals in vegetables varied according to sites. Proximate composition in both vegetable leaves recorded higher mean values for total ash (8.65-8.97), crude fibre (10.83-11.25), protein (4.96-5.08), Fat (3.05-3.29) and dry matter (65.58-68.85) indicating that they were rich in nutrients that promote healthy living. The mean levels of Zn (3.36±0.50) and Ni (0.03±0.01) in Lagos Spinach ; and Zn (2.80±0.36) and Ni (0.04±0.02) in African Egg-plant were generally lower than the FAO/WHO permissible limits except for Fe (14.96±0.86),(15.81±0.89) and Pb (1.12±0.11), (1.31±0.11) in both vegetables that were significantly higher (P |
