- Abstract
The purpose of this paper was to evaluate the mobility and toxicity of lead in the sediment collected from the artificial lakes Batllava and Badovci. Pollution indicators were used to confirm the level of sediment pollution such as contamination factor, pollution load index, geoaccumulation index and enrichment factor. The study shows that sediments from these lakes have lead contents that exceed values by international guidelines limits. According to lead content classification, lake sediments are classified as light to medium toxic. Lead concentration was also analyzed in the waters of these two lakes and concentration measured was at very low values compared to EEC Directive 98/83 respectively below the detection level <0.01 mg/L. The sediments of Badovc and Batllava lakes were analyzed for total lead content, and according to the results in Badovcit Lake the average value of Pb was 166 mg / kg, while in the Batllava Lake sediment, the average value was 30.6 mg/kg. Comparing with international guidelines and to some lakes in the region, the Badovc Lake sediments exceed the international guidelines values and the referent lakes of the region. In the Badovci Lake sediment, pollution indicators were CF 10.42 classified as very high, PLI 10.42 extreme, Igeo 2.09 medium to high and Ef 1.88 minimum. Whereas in the Batllava Lake sediment these values were CF 1.92 medium, PLI 1.92 medium, Igeo 0.38 low to moderate and EF 1.72 minimal. Organic matter, dissolved oxygen, pH and conductivity, play a role in the favor of lead bonding to the sediment. In this study, the contents of other metal in sediments have been investigated, which present important similarities with lead, such as copper and manganese. These lakes should be monitored more frequently due to the possibility of the changing lead content by changing environmental conditions. The Batllava Lake sediment in terms of lead content, according to the pollution indicators used it was in better condition compared to the Badovc Lake sediment.
