Toxic Heavy Metal And Salinity Assessment In Water Soil And Vegetables Around Meki Irrigation Farms

The concentration Heavy metals Pb Cr Cd macronutrients Na K Ca and physicochemical properties Temp. pH EC TDS of soil vegetable and water were investigated using standard procedures. Soil sample was taken using auger with 0 - 20 cm depth using zigzag method. To determine the statistical differences between more than two groups of data ANOVA were used and t-test were also used to compare between two groups of data. And each vegetables sample was collected from the same place where a soil sample was taken. Uncultivated area was taken as control. Except potassium all physicochemical parameters for both ground GW and surface water SW were within recommended range of the standards WHO and FAO for agricultural use. The pH for GW as well as SW was slightly alkaline. Except Pb Heavy metals concentrations for soil and vegetables samples were below the safe limits for human consumption. This high Pb levels in meki may probably attributed to more vehicular exhaust fumes. But when statistically evaluated using ANOVA heavy metals concentration in soil samples were all significantly different P0.05 from Controlled uncultivated area. This shows that anthropogenic activities leading cause of metal emission. The concentration of macronutrients for soils and vegetables analyzed in all parts are within the range set up by the standards. The main purpose of this work is to know the sources of heavy metals emission and to control it using different methods.
