TRANSFORMATION OF DIFFERENT SHAPE ORGANIC SUBSTANCE IN LADOGA WATERS IN CONDITIONS OF ANTHROPOGENIC EUTROPHICATION

By Tatyana Petrovna Kulish

Abstract

The new chemiluminescent express methods for determination of the hydrogen peroxide and peroxidase activity in the natural water have been developed. The structure of the aqueous humic substance was, studied according to the IR- and mass spectra. It has been determined firstly that as a result of the disbalance in the productive-destructive processes the significant changes taken a place in the organic carbon system in the lake water. The earlier conservative aqueous humic substance has been covered the destructive processes. During its transformation the carbon-hydrogen component of the aqueous humus molecule is changed. In its composition there is the basic quantity of the carbon, biogenic elements, metals and microelements which are in the lake water. The labile carbonic shape consists mainly of the phyroplankton and products of its living activity. It is imposible to understand the eutrophication processes and to evaluate the water contamination with the heavy metals and also characterize the productive-destructive processes in the lake without data on the transformation of the aqueous humic substanceAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
