A sea, a river or a lake are not just masses of water, but they must be viewed together with the creatures in them, as ecosystems. Billions of microscopic organisms are located at the bottom of lakes and rivers or found in suspension in their waters, acting on the chemical composition of the water. The anthropization of the environment has profound repercussions on aquatic ecosystems. As a result there is a change in the chemical composition of natural waters and imbalance of stability in biocenoses. Starting from these considerations the objectives pursued in carrying out the present study are: identifying the qualitative and quantitative structure of the diatomaceous flora, establishing their specific diversity, evaluating the level of saprobity, in order to evaluate the ecological status of the Butimanu-Dâmbovița lake water based on the biological diatom index (IBD).
