Lead, mercury and cadmium concentrations were measured in muscle, liver and gill in wild and farmed Barbus sharpeyi from Shadegan Wetland (SW) and Azadegan Aquaculture Site (AAS). Significant variation in metal values were evaluated in Students' tests at p > 0.05. Results showed: In B. sharpeyi high levels of cadmium, lead, and mercury were measured in gill (0.34, 0.68, and 0.06 mg kg dw). The concentration of metals was not significantly different ( p ≥ 0.05) in the muscle between SW (Cd, 0.24; Pb, 0.49 and Hg, 0.04) and AAS (Cd, 0.23; Pb, 0.49 and Hg, 0.04). Lead concentration was higher than cadmium and mercury in different organs ( p > 0.05). Cadmium, mercury and lead in different tissues of SW were higher than AAS and there was no significant difference between them ( p ≥ 0.05). Metal levels in different tissues were higher than WHO standard. [ABSTRACT FROM AUTHOR] |
