METHOD OF ASSESSMENT OF ENVIRONMENT Russian patent published in 2015 - IPC G01N33/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the ecology and can be used in assessment of the degree of toxicity of a certain area of the territory. Assessment of environmental state is carried out by assessing the purity of the atmosphere on the needles of the trees, and the needles are used of the trees of 2-3 years of age, which is cut at a height of 1.5 from the part of the crown facing the source of pollution, and the ecological state of the environment is assessed based on determining compliance of the detached needles to biological aspects by examination for signs of chlorosis and necrosis, the class of damage to needles, the class of drying of needles, and in case if the compliance to biological aspects is 95-100%, the class of damage to needles corresponds to needles without spots and needle drying class corresponds to un-dried needles, it corresponds to an environmentally safe area, if the compliance to biological aspects is 80-94%, the class of damage to needles corresponds to needles with a small number of spots, and the needle drying class corresponds to drying of 1/3 of the length of the needle, it corresponds to a zone of relative environmental well-being, if the compliance to biological aspects is less than 80%, the class of damage to needles corresponds to needles with large number of black and yellow spots, and the needle drying class corresponds to drying of more than 1/2 of the needle length, it corresponds to an area of high environmental risk.

EFFECT: increase in informativeness and reliability of assessment is achieved.
