Abstract:
In this study the effects of various amounts of dietary EDTA (ethylene di amine tetra-acetic acid) supplementation on the amounts of cadmium, mercury, lead and arsenic were evaluated over a growing period of 90 days. This research was conducted according to completely randomized design with 5 treatments including 1(the control), 2, 3, 4 and 5 containing different EDTA concentration of 75, 150, 300 and 600 ppm, respectively and 6 replicates. The average concentration of arsenic ranged from total weight, total length and body height in fingerling fishes were 2.1±0.06 g, 1.96±0.05 and 0.51±0.01 cm, respectively. The average concentration of arsenic ranged from 56 to 84.66 µg/kg in different treatments. The highest and lowest concentration of arsenic were observed in treatment 2 and 5 were significantly different among various treatments (P>0.05).The highest and the lowest concentration of mercury were observed in treatment 3 (129.33±2.4 µg/kg) and 4 (112.±332.02 µg/kg), respectively. The amounts of mercury in treatment 1, 4 and 5 were significantly different from treatments   2 and 3(P<0.05). Lead concentration ranged from 192 to 256 µg/kg, in which the treatment 4 showed a significantly different as compared to the other (P<0.05). The lowest and the highest concentration of cadmium were observed in treatments 2 (106.00±4.72 µg/kg) and 4 (113.0±4.61 µg/kg), respectively. The concentration of cadmium in treatment4 was a significantly different from treatments 1, 2 and5 (P<0.05).
