RAPID BIOINDICATION METHOD Russian patent published in 2010 - IPC G01N33/18 

FIELD: chemistry.

SUBSTANCE: method involves continuous measurement of behavioural and/or physiological reactions of aquatic organisms in natural conditions using measuring devices connected to a self-recording device or a computer and a signalling device. Bioindication takes place based on results of complex changes in functional characteristics of indicator organisms. Values of measured parametres are processed by the computer in real time separately for each specific indicator organism with subsequent averaging and integration of the results. Changes are evaluated from measurements of not less than three main parametres of behavioural and/or physiological reactions of indicator organisms and their fluctuation frequency. By comparing the current state of the indicator organism with its normal state and analysing the integrated measurement results, an alarm signal is generated automatically. The said signal indicates changes in conditions of the aquatic medium and degree of deviation from normal conditions. Bioindication is carried out using not less than two types of indicator organisms for one and/or more biotopes, where the biotopes used are different water layers or bodies.

EFFECT: increased reliability and efficiency.
