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 bottom sediment, occurred in spring (May) and summer (July, August). Total alkaline phosphatase activity in the bottom sediment of Szmaragdowe lake over the five-year period of study oscillated between 764.1 to 7938.7 nmol PO4źdm-3źh -1. In the littoral it ranged from 3107.4 to 7938.7 nmol PO4źdm-3źh -1, and in sublittoral from 764.1 to 3429.5 nmol PO4źdm-3źh -1.
