Abstract
In the present work, the bioaccumulation of Cr (III) by Artemia franciscana was investigated. Metallothionein protein plays a key role in the uptake of Cr (III) by Artemia and it was estimated by the silver saturation method. Artemia (Brine Shrimp) was subjected to Cr (III) initial concentration of 40 ppm which was reduced to 1ppm on 4th day of experimental condition with removal efficiencies of 97.5%. The number of organisms were varied to find out the maximum removal efficiency. The physical parameters such as pH were maintained in alkaline condition of 9, temperature was maintained at room temperature and 30 -35 of salinity condition was found to be optimum for the survival and reduction of chromium by Artemia.
