Heavy Metal Contents in the Soil and Leaves of Different Vegetables in Lagos State, Nigeria
Fatai Olakunle Ogundele , Anthony Inah Iwara and Chidinma Joy Jeremiah

Background and Objective: Previous studies on edible vegetables considered few vegetables and many did not assess the level of metals under the soil of leafy vegetables. The objective of the study was to assess the concentration of heavy metals in the soil and leaves of 8 vegetables (pumpkin, spinach, lettuce, green onion, curry leaf, scent leaf, water leaf and ewedu) frequently cultivated in Lagos State, Nigeria. Material and Methods: Edible leaves of the vegetables and soil samples at depth of 0-15 cm were randomly collected and analyzed for manganese (Mn), iron (Fe), copper (Cu) and zinc (Zn) using Atomic Absorption Spectrophotometer (AAS) technique. Results: The concentration of metals in the leaves of the selected vegetable plants showed that Mn, Fe, Cu and Zn had high concentrations in Green onion (0.038 mg kg1), Pumpkin (0.365 mg kg1), Pumpkin (0.008 mg kg1) and Curry and Spinach (0.005 mg kg1), respectively. The order of metal concentration in the soil was Fe>Mn>Zn>Cu. Conclusion: It was concluded that contents of heavy metals in the respective leafy vegetables were safe for consumption as justified by Accumulation Factors (AF) values.
