ABSTRACT
Aim of the study:
The purpose of the study was to analyze selected physicochemical indicators of water in Lake Rotcze (Łęczyńsko-Włodawskie Lake District, Poland) during selected months of the year to determine possible seasonal changes.
Material and methods:
Water samples for analysis were taken four times, once in each season. Temperature, pH, ammonia (NH3), nitrites (NO2–), nitrates (NO3–), phosphates (PO43–), total hardness (GH), and carbonate hardness (KH) were measured in the collected water samples. Additionally, the floristic composition of vegetation in the littoral zone was determined.
Results and conclusions:
The study of the seasonal variability of selected physical and chemical parameters of water in Lake Rotcze allows to form the following conclusions: in a shallow lake with intensely mixed waters, the water temperature varies seasonally as it is strongly dependent on air temperature, water pH remains stable throughout the year, and values of total hardness and carbonate hardness showed a decrease during the warm season.
