Sensory monitoring of the native state of natural waters

Resumo

A procedure has been proposed for express assessment of the degree of pollution of melt and snow waters with volatile aromatic compounds using a set of chemical sensors. The number of measuring units has been minimized to 2 for the yes/no detection (alarm system) of volatile aromatic toxicants in natural waters of different salinities. An algorithm has been developed for the extraction of analytical information on the presence of volatile compounds or salts in meltwater by the sorption efficiency parameters A_ij and their profiles (petal diagrams) or by cluster analysis.
