D. salina is a unicellular green alga. The individual effects of Cd 2+ (0.5 mg.L-1) at different concentrations of NaCl (1, 1.5 and 2M) on the growth (cell number and total chlorophyll content) of Iranian strain of Dunaliella salina were examined during 36 days of treatment. The results show that increase in salt concentration caused significant increase in cell number and chlorophyll content of D. salina. It seems such increase in growth rates is due to formation of CdCl2 and decrease of uptake of Cd 2+ by cells.
