Abstract

Abstract Poultry waste as enhancement for crop development has become a norm for nutrients’ source but their pollution potentials is a source for concern. Thus, this study aimed at assessing proximate compositions and heavy metal accumulation in organs of Amaranthus spinosus and Talinum fruticosum handpicked from three poultry faecal sites in Badagry, Lagos State. Leaves and roots of A. spinosus and T. fruticosum as well as soil samples were collected from Yafin, Agric and Badagry dumpsites in Badagry Local Government and these were subjected to proximate and heavy metal analyses using standard analytical procedures. Data obtained were analyzed using mean-standard deviation. Proximate analyses of A. spinosus and T. fruticosum from three faecal sites contained appreciable Moisture, protein, carbohydrate, fiber, ash, and fat contents. Also, heavy metal analyses of the vegetables from the three faecal sites ranged as follows: Cd: 0.01-0.05mg/100g in leaves; 0.04-0.12mg/100g in roots, Co: 0.04-0.05 in leaves; 0.04-0.12mg/100g in roots, Cr: 0.58-0.84mg/100g in leaves; 0.91-1.01mg/100g in roots, Cu: 0.27-70.51mg/100g in leaves; 0.50-58.55mg/100g in roots for A. spinosus; Cd: 0.04-0.07mg/100g in leaves; 0.06-0.12mg/100g in roots, Co: 0.02-0.06mg/100g in leaves; 0.08-0.34mg/100g in roots, Cr: 0.05-0.12mg/100g in leaves; 0.04-0.23mg/100g in roots, Cu: 61.55-121.81mg/100g in leaves; 48.45-147.45mg/100g in roots for T. fruticosum and Cd: 3.53-9.05mg/100g, Co: 0.14-0.69mg/100g, Cr:0.14-4.22mg/100g: and Cu: 2.59-8.11mg/100g in soils for all three dumpsites sampled. However, all metals analysed were below WHO limits for vegetable and soils except cobalt, copper and chromium. Thus, locals should be advised against consumption of vegetables from dumpsites since toxic substances often accumulates in the environment and maybe hazardous to man’s health.
