| Abstract: | The results of a one-year detailed water quality study of the Pinios river are presented. Physicochemical parameters (pH, conductivity, DO) did not show significant differences neitherbetween sampling sites, nor between sampling periods. Nutrients(nitrogen and phosphorus compounds) showed temporal variationsprobably caused by seasonal variations in runoff nutrient fromweather events. Heavy metals (Pb, Cd, Cr, Cu, Ni) were determinedin the dissolved fraction and the variations observed were related to the geology of the examined area and the influence from anthropogenic sources. Statistical analysis of variance ofthe most important chemical parameters and heavy metals showedsignificant variation between sampling periods, but insignificantones between sampling sites. |
