EVALUATION OF HEAVY METAL SCAVENGING COMPETENCE BY IN-VIVO GROWN RICCINUS COMMUNIS L. USING ATOMIC ABSORPTION SPECTROPHOTOMETER

AJEET PRAKASH AND PRASANN KUMAR1

Abstract

The present study was conducted to evaluate the scavenging efficiency of in-vivo gown Riccinus communis L. for the uptake of Cd, Pb, Cr and Ni. Excessive heavy metal accumulation can be toxic to most plants leading to reduction in seed germination, root elongation and biomass production; inhibition of chlorophyll biosynthesis as well as disturbance in cellular metabolism and chromosome distortion. For studying the heavy metals load of sewage sludge and their effect on crop quality in relation to non applied sites, solid sludge and oil plant Riccinus communis L. was collected from seven STPs viz. Howrah, Garulia, Bhatpara, Nabadwip, Srirampur, Kona, Chandannager and from the Periurban areas viz. Nadia/Chakdaha/Ektapur(N/C/E), Nadia/ Chakdaha/Pumlia, Nadia/Chakdaha/Sikarpur(N/C/S), Nadia/Chakdaha/Tatla (N/C/T). The results suggest that oil plant like Riccinus communis L. has more scavenging capacity for Pb and Cr and if this plant is cultivated in sites abundant with above heavy metals, this would scavenge the heavy metal toxicity from the soil.
