Abstract:
Despite array of benefits link to consumption of fresh fruits in human growth and development, the major problem is that most of them are reservoir for heavy metals which their excessive are dangerous and deleterious to function of human and animal system. Therefore, there is need for frequent assessment of level of heavy metal in our fruits to ascertain the level of conformation with the standard intake in human body. The current study is aimed at examine the level of heavy metal in fruits sold at Sekona Market in Ede South Local Government Area Ede, Osun state. Seven samples of the fruits were obtained from Sekona market. The edible portion of the purchased fruit samples were properly separated washed and chopped into small pieces using a knife. The fruits were air-dried and then dried in an oven at 80 °C. Dried samples of the fruits were ground into a fine powder (80 mesh) using a commercial blender. Heavy metals in fruit samples were extracted by acid digestion and analyzed for Lead, Chromium, Cadmium, Nickel, Zinc, Copper and Cobalt using a flame atomic absorption spectrophotometer. The results obtained showed that Banana, Apple, Orange, Watermelon, Cucumber, Pineapple and Carrot had Lead (0.064±0.00, 0.091±0.00, 0.0118±0.01, 0.105±0.01, 0.211±0.03, 0.130±0.02 and 0.151±0.01mg/kg), Chromium (0.073±0.00, 0.085±0.00, 0.125±0.04, 0.163±0.02, 0.190±0.00, 0.116±0.01 and 0.170±0.01 mg/kg), Cadmium (0.071±0.00, 0.047±0.00, 0.051±0.00, 0.025±0.00, 0.050±0.01, 0.062±0.00 and 0.043±0.00 mg/kg) and Nickel (0.130±0.01, 0.110±0.00, 0.0155±0.02, 0.230±0.03, 0.185±0.03, 0.165±0.02 and 0.190±0.01), Zinc (1.282±0.04, 1.206±0.17, 2.00±0.04, 2.625±0.03, 2.840±0.02, 2.300±0.03 and 2.580±0.04 mg/kg), Copper (0.065±0.00, 0.040±0.03, 0.120±0.03, 0.330±0.02, 0.240±0.00, 0.300±0.00 and 0.260±0.01 mg/kg) and Cobalt (0.063±0.00, 0.042±0.02, 0.090±0.01, 0.102±0.02, 0.145±0.01, 0.163±0.01 and 0.180±0.02 mg/L). The level of heavy metals in fruits examined is within the required stipulated standard of heavy metals permissible level except in few Cases.
