Population status and distribution pattern of Indian Blue Peafowl (Pavo
cristatus L.) in Thuraiyur area of Trichy District, Tamilnadu, Southern India.

Abstract :

The green alga Chlorella marina Butcher was investigated in the laboratory for accumulation of six heavy metals, such as chromium, cadmium, cobalt, copper, nickel and lead. The cultures were grown in estuarine water medium mixed with different concentrations of the individual metals. The baseline metal concentrations in C. marina were shown to be in an order of Cu> Pb> Co> Cd> Ni> Cr under normal culture conditions. In the experimental groups, the metal uptake capacity of the alga was Ni> Pb> Co> Cu> Cd> Cr at equilibrium. When assessed using the bioconcentration factors, metal accumulation by C. marina was demonstrated to be the most efficient at a concentration of 0.001 mg L' for Cr, Cd and Co and at 0.01 mg LS1 for Cu and Pb. This study suggests that C. marina can be a source of mineral supplements in mariculture.
