ABSTRACT

Dynamics of the main hydrobiological indices and integral characteristics, including kinetics of the process of self-purification of the fish pond from phenol, and also the composition of free fatty acids of the surface film of water of this water body, were studied during the vegetation season in 1997. Three functional types of the aquatic ecosystem of the pond alternating during the vegetation season were distinguished by the standard methods of statistics. Each functional type was characterized by the specific rate of self-purification, and also by the specific composition of free fatty acids. It has been found that the composition of free fatty acids of the surface film of water belongs to integral structural characteristics giving an indication of the process of self-purification depending on seasonal dynamics of phytoplankton, and also on the hydrochemical regime of a water body.
