Abstract
Soil samples from selected site of Yamuna Riverine Ecosystem in Delhi Region were collected and analysed for various soil quality parameters and heavy metal concentration following standard testing procedures. Half of the Yamuna riverside soil was considered as unpolluted soil and other half was made artificially polluted by spiking of heavy metal salts Pb(CH3COO)2, CuCl2.2H2O, and ZnSO4.7H2O in a concentration of 0.6 gm/kg, 0.7 gm/kg, and 0.8 gm/kg of each of the salts. Experiment was carried out in18 pots sown with coriander and fenugreek seeds separately as well as in combinations. Metal concentration in plants and soil was analysed separately using AAS. Soil pH, NPK was significantly higher (p<0.05) for control soil than for the treated one. Organic carbon content had no significant variation (p>0.05) with respect to variation in the heavy metal contents in the soils. Soil biological activity, dehydrogenase and respiration were found varying significantly (p<0.05) due to the presence of heavy metals. Copper was observed significantly higher (p<0.05) in shoots of coriander plants in treated soil. Significantly higher (p<0.05) value of Zn was observed in shoots of fenugreek plants grown in treated soil pot and lower in shoots of coriander plants grown in control soil. In case of Pb accumulation, there was no significant variation (p>0.05). Accumulation of heavy metals (Cu, Zn, Pb) in roots of coriander and fenugreek plants showed differential behaviour with different treatments of the experimental soil. Significantly higher (p<0.05) Cu accumulation in the roots of coriander plants and Pb and Zn in roots of fenugreek plants grown in treated soil was observed. However, there was no significant variation (p>0.05) in Pb accumulation in the roots of both the experimental plants.
