Essential and Practical Bioindication Methods and Systems for the Water Quality Assessment

Previously we are discussing the main systems of the water quality classification [1] that based on the Ecosystem model of [2]. The major point of this approach is the amplitude of the water variables that covered of all possible parameters for surface and technical waters, as well as the amplitude of variables in which the aquatic ecosystem can survive. Considering that water quality assessment is rather expensive, elaboration of express-methods of its assessment is an urgent problem. Therefore, the bioindication methods were involved for the water quality assessment. This approach is based on the hierarchic organization of the biotic community, which is described by the model of trophic pyramid [1]. The distribution of the groups of organisms or species over the intervals of the environmental factors is also of considerable importance. The aim of present study is to describe the major most used essential and practical bioindication methods and systems for the water quality assessment as a part of the surface water quality monitoring.
