| Abstract: | Lake Vegoritis, in the northwestern part of Greece, accepts the pollutants of the municipal and industrial activities in the area (lignite burning power plants and a nitrogen fertilizer factory). The PIXE external beam technique was used for the elemental analysis of water and sediment samples in order to determine the load of metals in the lake and obtain information for managing its environment. From our results it is deduced that the anthropogenic activities in the drainage basin do not have so far any significant impact on the Vegoritis Lake, as far as the elements studied are concerned. However, there is indication that other pollutants are introduced, mainly along the Solou stream, which cause precipitation of the metals. |
