The Variation in Trace Minerals Content (Zn, Cd, As, Pb, Mn, Cr) of Irrigation Water, Soil and Vegetables Along Shagari Quarters Irrigation Site of Kano State

Abstract

This work involves studying the variations of trace mineral contents (Zn, Cd, As, Pb, Mn and Cr) of irrigation water, soil and vegetables at shagari quarters irrigation site of Kano State of Nigeria between the months of June to December 2020. The irrigation water, Soil and vegetables samples were collected from shagari quarters irrigation site and analyzed using Standard analytical methods. The result of the analysis revealed that the concentrations (ppm) of the minerals ranged from Zn (0.71 to 1.75 for sample 5 to sample 2), Cd (0.00 to 0.003 for samples 3, 4, 5, 6, 7, 8 and to 2), As (0.00 to 0.48 for samples 6, 7, 8 and 9 to 2), Pb (0.00 to 0.008 for samples 3, 4, 5, 6, 7, 8 and to 1 and 2), Mn (0.11 to 1.50 for sample 4 to 2) and Cr (0.05 to 0.34 for sample 4 to 5 and 9). The minerals analysed are within the specification set by National Agency for Foods, Drugs Administration and Control (NAFDAC) and as such the Shagari quarters irrigation site as at June to December 2022 is not polluted and the crops are safe for human consumption. However, continuous monitoring is required.
