Water in the Miedwie Lake were the subjects of a five-year study (2008-2010). Total alkaline phosphatase activity was determined seven times a year in these environments. The study on the water demonstrated that the top sublittoral layer (1 m) featured the highest alkaline phosphatase activity among all the analyzed zones. A study of seasonal fluctuations showed that a maximum total alkaline phosphatase activity, both in the water occurred in spring (May) and summer (July, August). Basing on this parameter no increase in eutrophication process in the Miedwie Lake was determined in the course of a 3-year study.

The progress of civilisations causes changes in the water catchment areas lakes. aquatic waters are order - phosphorus and nitrogen compounds. Level of activity alkaline phosphatase (APA) has an important impact on the chemical and biological processes taking place in the aquatic environment. APA belongs to a group of indicators, who tells us about the extent limitations to development of biomass in the tank water. Water of Szmaragdowe lake were the subjects of 2008-2012 (July – September). Total alkaline phosphatase activity was determined seven times a year in these environments. A study of seasonal fluctuations showed that a maximum total alkaline phosphatase activity, both in the water and in the bottom sediment, occurred in spring (May) and summer (July, August). The results presented in in tables 1 to 5 demonstrate that total alkaline phosphatase activity in the waters of Szmaragdowe lake over the five-year period of study oscillated between 242,3 to 642,1 nmol PO4•dm–3•h–1. The oscillation range in both zones of the analyzed water body was similar. In the littoral it ranged from 312,3 to 642,1 nmol PO4•dm–3•h–1, and in sublittoral from 242,3 to 536,9 nmol PO4•dm–3•h–1.

Postęp cywilizacyjny wywołuje zmiany na obszarach zlewni jezior. Akweny wodne zostają obciążenie głównie związkami biogennymi - fosforem i azotem. Poziom aktywności alkalicznej fosfatazy (APA) ma istotny wpływ na procesy chemiczne i biologiczne jakie zachodzą w środowisku wodnym. Badaniami objęto wodę jeziora Strażym. Próbki do badan pobierano w okresie od lipca do września 2009 roku. Badania dotyczące wody wykazały, że spośród analizowanych stref najwyższa aktywność fosfatazy zasadowej posiadała górna warstwa sublitoralu. Z dokonanej analizy wahań sezonowych wynika, _e maksimum aktywności ogólnej fosfatazy zasadowej w wodzie występowała w badanym jeziorze w lipcu 2009 roku.

APA belongs to a group of indicators, who tells us about the extent limitations to development of biomass In the tank water. To estimate differentiation of activity of total alkaline phosphatase in water of the Strazym Lake, in time July - September of 2009. Studies upon water revealed that, among the zones analyzed, upper sublitoral layer was characterized by the highest phosphatase activity. From the analysis of seasonal oscillations it follows that activity maximum for alkaline phosphatase, both in water, occurred in July 2009. Overall activity in alkaline phosphatase in water considered lake fluctuated seasonal throughout the period test bed.
