METHOD OF MONITORING POLLUTION OF NATURAL MEDIA BY TECHNOGENIC SOURCE Russian patent published in 2014 - IPC G01N33/00 G01W1/00 G01N1/22 A01G15/00 

FIELD: chemistry.

SUBSTANCE: method includes the selection of a totality of substances, for which the following procedures will be performed: monitoring of the region around a point source, determination of a route of sampling by the seasonal wind direction and drawing a map of isolines of pollutions on the basis of obtained data. A vector of the prevailing seasonal wind direction is selected. On the said vector sampling for each pollutant is carried out in two points r1 and r2, spaced from the point source at distances in the interval of 5 heights of a source (h) to 15 heights of the source. Coefficients B=ln(q1/q2·exp(C·((1/r2)-(1/r1))))/ln(r1/r2) and A=q1/(r1B)·exp(-C/r1), where q1 and q2 are concentrations of a pollutant in the points of sampling r1 and r2, C=30 h, are calculated. A single-dimensional profile of the pollutant concentration is calculated by the direction of the prevailing wind by formula F(R,A,B)=A·RB·exp(-C/R), where R is the current distance from the source, with transition to an area image of the pollutant distribution in the region being performed by multiplication of the specific concentration F(R,A,B) by a transposed function of the wind rose G(φ+180°), known from meteorological observations for the said region in the selected season.

EFFECT: method makes it possible to estimate a degree of pollution of the environment from the technogenic point source in a quick and accurate way.
