ABSTRACT
The main purpose of this work was defining seasonal changes of biogenic elements in Lutownia river flowing through the protected areas of Bialowieza Forest. The range of analyses included measurements of temperature, water reaction, electrolytic conductivity, biogenic elements level (ammonium nitrogen, nitrates III i V, phosphates) and dissolved oxygen. On study area analyzed water corresponded to II class of water purity; level of dissolved oxygen was low and content of biogenic elements indicates an average pollution. The Lutownia river brings many urban pollution form near Teremiski village. This fact influences on water purity level and eutrophication of surrounding forest areas. The water of Lutownia river flowing through protected areas Bialowieza Forest does not meet the requirements of water purity. The main problem of last years is sudden reduction water level until the complete disappearance in several summer months, what cause the negative changes in habitats.
