Abstract
This study was aimed to evaluate the metals concentration in agricultural soil and vegetables irrigated by different irrigation sources. For this purpose agricultural soil and eight vegetables used for commercial consumption were collected from waste-water and tube-well water irrigated sites of Lahore district. Metals i.e. iron (Fe), sodium (Na), potassium (K), magnesium (Mg) and calcium (Ca) were analyzed via flame atomic absorption spectrophotometer. Concentration of metals in soil and vegetables irrigated by wastewater was higher considerably as compared to the soil and vegetables irrigated by tube well water. Among heavy metals concentration in vegetables irrigated by waste-water, trend was appeared as K > Na > Ca > Mg > Fe, while vegetables cultivated by tube-well water, trend was appeared as K > Ca > Na > Mg > Fe. Similarly, leafy vegetables accumulated higher heavy metals levels as compared to non-leafy vegetables.
