The results of measurement of physi

The results of measurement of physicochemical parameters (pH, electrical conductivity, sulphates, chlorides, temperature, turbidity, total hardness, iron, manganese, copper, dissolved oxygen, oxygen saturation, total suspended solid, ammonium nitrogen, total nitrogen and orthophosphates) are presented in Table 2. Water temperature ranged between 3.6 and 12 °C during the time of study, while air temperature was minimum (– 1°C) in December and maximum (27 °C) in May.
