Analysis of water chemistry in the alpine lake Kolové pleso, the Tatra Mountains
Abstract
The study focuses on the long-term observation of physical variables as well as inorganic and organic contents in the water of the lake Kolové pleso (High Tatras). Physical variables were measured directly at the sampling site at regular monthly intervals. The chemical composition of the collected water samples was analysed by photometric method. Organic substances were detected by GC/MS and chemical oxygen demand (COD) method. The study confirmed the seasonal dependence in water temperature, total water hardness and oxygen saturation. The amount of sulphates and nitrates also varied over the seasons. Significant inter-annual differences were also observed in the amount of athracene.
