METHOD FOR ASSESSING ENVIRONMENTAL POLLUTION Russian patent published in 2021 - IPC G01N33/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine and can be used in ecology and hygiene to study the objectivity of assessing the ecological state of the environment. The method for assessing environmental pollution includes determining the factors and levels of pollution by the volume of technogenic emissions into the atmosphere, in tons (A), pesticides introduced into the soil, kg/ha (B), pollutants in wastewater, t/ha (C), and the integral index of environmental pollution. Also, in addition, within 5 years, the volumes of heavy metals polluting the soil (D), mg/kg, pollutants from livestock products (E), t/ha, and household waste (F), m³/km², subject to the value of D equal to 0.9-9.9 mg/kg, E - 0.03-0.60 t/ha, F - 20.63-100.00 m³/km²and with a value of A equal to 5.0-999, 0 t, B - 0.1-1.0 kg/ha and C -0.1-1.0 t/ha, for each of the parameters, the environmental pollution is preliminarily assessed as level I and 1 point is assigned; under the condition D equal to 10.0-15.5 mg/kg, E - 0.7-2.0 t/ha and F - 101.0-999.0 m³/km²and with the value of A - 1000.0- 10000.0 t, B - 1.1-2.0 kg/ha and C 1.1-100.0 t/ha, for each of the parameters, the level of contamination is preliminarily assessed as II and 2 points are assigned; provided D is more than 15.6 mg/kg, E is more than 2.1 t/ha and F is more than 1000.0 m³/km²and if A is more than 10000.0 t, B is more than 2.0 kg/ha and C is more 100.0 t/ha, for each of the parameters it is preliminarily estimated as III level of pollution and 3 points are assigned, after which the index of ecological pollution of the environment (N) is calculated according to the formula:

where K is the level of pollution in a given (i) year from the corresponding (j) factors, m is the number of factors, n is the number of observed years - 5 years, and, provided the value of N is from 1.13 to 1.30, it is estimated as a favorable ecological territory , with a value of N equal to 1.33-1.60, is defined as a conditionally favorable ecological territory, with a value of N equal to 1.63-2.77, it is defined as an unfavorable ecological territory.

EFFECT: invention improves the objectivity of the assessment of the environment, as well as improved control over the environmental situation.
