Abstract
Concentrations of toxic elements (lead, cadmium, mercury, and arsenic) were measured in water, sediment, and four commercial fish species (Cyprinus carpio, Hypophthalmichthys molitrix, Silurus glanis, and Esox lucius) and their tissues (muscle, liver, and kidney) from Saničani Lake, Bosnia and Herzegovina. The concentration of toxic elements was measured by atomic absorption spectrometry. Toxic element concentrations were significantly affected by the fish species and tissues sampled. The lead was the most heavily deposited element in lake sediments and waters. The highest concentrations of Pb and Cd were in the kidney in all four fish species. Concentrations of Hg and As were higher in the muscle than in the kidney and liver in all four fish species. The toxic element concentrations in all examined tissues were significantly higher in Silurus glanis and Esox lucius than in the other fish species examined. Concentrations of all tested elements were present in the fish muscle at differe...nt levels, but these levels were under the maximum levels allowed by the European Union and FAO/WHO. Accordingly, fish meat from this lake is acceptable for human consumption.
