Influence of calcium presence on the absorption of cadmium by the rock oyster Saccostrea cucullata from Persian Gulf (Ostreidae; Bivalvia) in laboratory conditions
Bioaccumulation of Cadmium as a function of its concentration and exposure time inSaccostrea cucullata (Ostreidae; Bivalvia) has been studied in filtered sea water and in laboratory. Results showed that the accumulation of Cd by gills was greater than other organs such as visceral mass. At 150 µg /l saturation as a function of time appeared in uptake of Cadmium by gills, all binding sites for Cd may be...

Phytosociology of roadside communities to identify ecological potentials of tolerant species
Roadside vegetations are open to contaminations of diverse heavy metals and other gaseous pollutants, and to physical disturbances of being trampled by pedestrians and crushed by vehicles continuously. Being a biodiversity-rich region of the world, roadsides of Southwest India, are expected to be rich in unique pollution-tolerant species. Tolerant plants in heavy metal polluted roadsides may be excluders or accumulators...
