biotesting

The results of experimental researches are presented to metrology descriptions establishment of biotesting methodology for determine the chronic toxicity water with the usage of Ceriodaphnia affinis Lilljeborg crusta-ceans. It has been used the potassium dichromate (K2Cr2O7) as an etalon substance.

Influencing of biocorrection of determination results obtained via multifunction monitoring of natural envi-ronments was analyzed. For the increase of authenticity of monitoring results, it is necessary to combine the methods of bioindication and biotesting with physical and chemical methods, and mathematical design as well. While determining the supersmall contamination amounts it is expedient, additionally, to utilize the factor analysis of different modifications.
