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.
