Abstract: The purpose of this work is to determine the hydrochemical parameters of the water of the river Seret and the features of the accumulation of heavy metals by bivalve molluscs Unio pictorum L. to predict the chemical contamination of the reservoir in the near future. The hydrochemical parameters such as pH, oxygen, total water hardness, nitrates, nitrites, ammonium cations, phosphates, chlorides, permanganate oxidation were analyzed. The concentrations of manganese, zinc, copper, plumbum and cadmium in the reservoir and the peculiarities of their accumulation by bivalve mollusks Unio pictorum L. were determined. The possibility of using economic and mathematical modelling tools and statistical methods based on correlation-regression analysis using modern Matlab information systems to identify correlations between chemical indicators of water quality and biological molluscs for modelling the environmental situation of the river Seret and assessing the contribution of the studied indicators in pollution of small rivers is shown.
