ABSTRACT
Heavy metal contamination is of special concern due to widespread reports emanating both from India and abroad about various diseases and disorders observed both in human and livestock due to metal toxicity. The present study was conducted to evaluate the scavenging efficiency of in vivo gown Zea mays L. for the uptake of Cd, Pb, Cr and Ni. For studying the heavy metals load of sewage sludge and their effect on crop quality in relation to non-applied sites, solid sludge and Zea mays L. were collected from seven STPs viz., Howrah, Garulia, Bhatpara, Nabadwip, Srirampur, Kona and Chandannager, and from the periurban areas viz., Nadia/Chakdaha/Ektapur (N/E), Nadia/Chakdaha/Pumlia (NP), Nadia/Chakdaha/Sikarpur (NS) and Nadia/Chakdaha/Tatla (NT). The results suggesed that plant like Zea mays L. had more scavenging capacity for Cd as co-pared to lead, chromium and nickel. If this plant is cultivated at these sites in abundant with above heavy metals, this would scavenge the heavy metal toxicity from the soil to the limited extent
