Assessment of Cadmium and Lead in Soil and Tomatoes Grown in Irrigated Farmland of the Kaduna Metropolis Nigeria
並列摘要
The objective of this study was to determine the level of cadmium and lead in soil and tomatoes grown in irrigated farmland of Kaduna metropolis. Twenty sampling sites were selected with one control site.Concentration of these metals was determined using atomic absorption spectrophotometer. In the soil analysis it was found that most of the concentrations were higher than obtained in the control site. The concentrations of tomatoes samples for cadmium were found to be in the range of 0.10±0.10 to 1.33±0.23μg/g and lead ranged from 0.92±0.08 to 4.67±1.29μg/g. This also shows that concentrations of cadmium and lead in tomatoes samples were above FAO/WHO Allimentarious standard. Pearson correlation shows positive correlation between soil and vegetable. Therefore, consumption of tomatoes from these study areas may constitute health hazard to human as at the time of this research work.
