Abstract: 

Artemia urmiana is the only animals that bear difficult conditional and live in Urmia lake.This species is very important food chain of lake, so study the effects of different pollutants on it has a special importance. In this research the growth of Artemia which was exposed to different doses of Zinc and Cadmium, and then the interaction between Zn and Cd was studied. In this way, the nauplieus of Artemia exposed to 23, 68 and 114mg/L Zinc and 13, 26 and 39mg/L Cadmium. Length of the species in terms of micrometer was taken into consideration as growth index and was studied on first, 5th, 11th, and 17th of the Artemia life. The results show that growth of Artemia in compared to control group was decreased and also the length of life was decreased. Then four group of adult Artemia were exposed to 5, 10 and 15mg/L Zn and Cd for 24 hours. And bioaccumulation of heavy metals were measured and compared with control group. Results detected that Zinc has a neutralizing effect on poisonousness of Cadmium and causes cadmium absorption to decrease.
