Calculation models for the dispersed composition integral functions approximation of the dust in the air

The danger of the small dust particles' influence with sizes PM10 and PM2.5 is indicated. Computational models for approximating the integral functions of the dispersed dust composition are presented. The optimal planning problem is solved under the conditions of the Gauss-Markov theorem for determining the regression coefficients and a set of functions of a two-link and three-link spline.
