The objective of the present study was to compare the content of polyphenolic compounds in sediments of lakes with different types of catchment. Sediment samples for analysis were collected from the littoral and profundal zones of lakes with field or forest catchments. The study material was supplemented with select aquatic plant species. Basic physicochemical properties and the content of polyphenolic compounds were determined in the material applying the Folin-Ciocalteu method.
The results reveal that bottom sediments of forest lakes were distinguished by a higher content of polyphenols compared to sediments of field lakes (0.290 and 0.200%om). Aquatic plants were characterized by a highly diverse content of polyphenols (0.74-2.67%om); shining pondweed had the highest content.
