Abstract
Determination of heavy metals in roasted plantain sold along major roads in Lagos, South west, Nigeria was investigated using Atomic Absorption Spectrophotometry method. Roasted plantains were randomly purchased without specific order from five vendors by the road sides from Agege, Iyana-ipaja , Oshodi, Ojodu-Berger and Ogba. All the samples were analyzed for levels of heavy contaminants such as Lead, Copper, Zinc, Arsenic, Cadmium, Iron, Chromium, Manganese, Aluminum and Potassium. The results showed that Lead ranged from 0.08-0.26mg/kg, Copper ranged from 3.27-7.57mg/kg while Zinc varied from 1.72-4.90mg/kg in all the samples. Iron ranged from 6.47-11.73mg/kg, Chromium ranged from 0.05-0.14mg/kg while Manganese varied between 0.09-0.35mg/kg. The level of Aluminum as revealed by the analyses ranged from 7.57-11.26mg/kg while Potassium varied between 5.72-8.63mg/kg. Food and Agricultural Organization/World Health Organization (FAO/WHO) for example had recommended an optimum levels of 0.2mg/kg (Lead), 0.02-0.38mg/kg (Copper), 0.04mg/kg (Manganese) and 0.05mg/kg (Cadmium) for foods. Therefore, this study has shown that most of the roasted plantains were contaminated with some of these heavy metals, indicating that consumers of this snack without being mindful of the health implication from the environment where it is obtained may be exposed to health risks associated with presence of metals.
