Analysis of Iron and Zinc in Soil and Spinach Grown in Irrigated Farmland of Kaduna Metropolis Nigeria

Abstract

This study was conducted to determine the level of iron and zinc in soil and spinach 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 most of the concentrations were higher that obtained in the control site. In spinach samples, it found that mean concentration for iron was found to be in the range of 1.84±1.60μgg-1 to 14.47±3.42μgg-1 and zinc ranged from 0.57±0.49μgg-1to 18.49± 1.91μgg-1.This also shows that concentrations of iron and zinc in spinach were within FAO/WHO Allimentarious standard. Pearson correlation shows positive correlation between soil and vegetable. Therefore, consumption of spinach from these study areas may not constitute health hazard to human at the time this research work.
