Abstract

Evaluation of heavy metals in vegetables and soil of agricultural fie1ds of Kathmandu valley was conducted. Highest accumulations of copper (65.5 mg kg-1;, lead 146.75m g kg-1) and cadmium( 2 mg kg-1) from Shankhamul; nickel (29.25mg kg-1) from Nakhu; cobalt (15.25mg kg-1) and manganese (675 mg kg-1; from Balkhu; chromium (73.75 mg kg-1; from Banasthali, zinc (162 mg kg-1) and iron (75636 mg kg-1; from Khusibun were recorded in soil of agricultural fields. Highest accumulations of Cu, Co and Zn were recorded in spinach and Pb in red radish; Ni, Cr and Fe was recorded in broad leaf mustard and Mn in cress leaf while considering the mean of each vegetables studied. Concentration of non-essential but toxic metal like Pb was higher than the normal plant value (0.1-10mg kg-1) in all the vegetables (except potato) collected from different sampling sites.
