Ecological characteristics of lakes in north-eastern Poland versus their trophic gradient. 5, Chlorophyll content and visibility of Secchis disc in 46 lakes
Chlorophyll content and visibility of Secchi's disc in spring and summer have been described for 46 lakes differing in their trophic state and mixia (dimictic and polymictic lakes). Chlorophyll content increased and visibility decreased along with increasing lake trophic state. For spring and summer the following relationships have been demonstrated: significant positive correlation between content of total phosphorus and chlorophyll, negative correlation between chlorophyll content and visibility, and lees significant positive correlation between content of total nitrogen and chlorophyll in summer. No relationship was found between concentration of silicates and chlorophyll.
