METHOD FOR DETERMINING ENVIRONMENT QUALITY BY EPR-SPECTROSCOPY OF LICHENS Russian patent published in 2015 - IPC A01G15/00 G01N33/00 

FIELD: agriculture.

SUBSTANCE: invention relates to ecology. The invention provides a method of determining the quality of the environment by EPR-spectroscopy of lichens, including the collection of samples of lichen thalli from the trunks of trees growing in an industrial and background area, which is not contaminated by anthropogenic emissions into the environment, cleaning, drying, grinding, which is characterised by the fact, that drying is carried out at a temperature of 85-95°C to constant weight and ground, the EPR spectra are removed, from which the concentration of paramagnetic centres is determined, in the excess of the concentration of the paramagnetic centres in the lichen samples collected in the industrial zone, over the concentration of the paramagnetic centres of the lichen samples from the background area the low quality of the environment in the industrial zone is detected, and in case of equal concentrations of the paramagnetic centres - the acceptable quality of the environment is detected, and in the studies the samples of the same species of lichen are used.

EFFECT: invention provides the improvement of the method of lichenoindication, improvement of the quality of evaluation of the test objects, obtaining objective result.
