In the process of sanitary and chemical control over the content of pesticides in the air, air sampling is of great importance, which largely determines the correctness of the analysis results. The accuracy of this selection depends on many factors, including the use of an absorption medium with high absorption efficiency. The reason for the main errors in air sampling is that it does not take into account the state of aggregation of the substances under study, the concentration mechanism and properties of the absorbing medium, the presence of accompanying impurities, the possibility of chemical transformations of the analyzed compounds [6].

As a result of a comprehensive study of the problem of air sampling to determine the content of pesticides in it, it was established that it is necessary to comply with certain criteria and select the optimal absorption medium, which at present, in particular, are polymers, including domestic polyurethane foam, which has a high absorption efficiency.

Further in-depth study of the mechanism of sorption of pesticides by polyurethane foam will make it possible to more fully solve the problem of sampling air containing vapors of pesticides of various chemical structures.
