Abstract: 

The results of assessing of Individual and Mixed amounts of Transmission of Heavy Metals (Cu, Cd) and (LAS) detergent to Rutilus frisii kutum food chain show that the heavy metal(Cadmium) has transmitted to the food chain from the amount of permissible limit added to Scenedesmus obliquus culture medium. The amount of culture medium is 0.0127 ppm, ranged from 0.0041 in the polluted Scenedesmus obliquus to 0.0015 in Daphnia magna, while this amount is not significant in Rutilus frisii kutum fed on polluted Daphnia magna. This amount in Rutilus frisii kutum fed on polluted Scenedesmus obliquus was 0.002 ppm and the amounts of transmission in food chain were calculated as 32%, 8% and 16%. Copper heavy metal transmission from the amount of permissible limit added to Scenedesmus obliquus culture medium with amount of 0.15 ppm was 0.07 in polluted Scenedesmus obliquus, 0.02 in Daphnia magna and insignificant amount in Rutilus frisii kutum. In Rutilus frisii kutum fed on polluted Scenedesmus obliquus, the amount of 0.02 was achieved and transmission to food chain was 46%, 13% and 13%. The transmission amount of (LAS+Cd) from the amounts of pollutants permissible limits added to Scenedesmus obliquus culture medium with the amount of 2.153 and 0.0127 ppm were 0.007 in polluted Scenedesmus obliquus and 0.003 in Daphnia magna, while this amount in Rutilus frisii kutum fed on Daphnia magna reached to 0.001 ppm and in Rutilus frisii kutum fed on polluted Scenedesmus obliquus reached to 0.003 ppm and the amounts of transmission to the food chain were 58%, 25%, 8% and 25%. Moreover, the achieved results from the transmission of (LAS+Cu) mixture showed that from the amounts of pollutants permissible limit added to Scenedesmus obliquus culture medium with amount of 2.153 and 0.15 ppm were 0.09 ppm in polluted Scenedesmus obliquus. The amounts of transmission in food chain ranged as: 60%,33%,6% and 45%. The results showed that the percentage of Cu and Cd transmission in to food chain is of a significant amount individually or mixed with LAS.
