The article is devoted to the process of air pollution as a result of the production and application of paints and varnishes used in the construction industry. In the process of pollution in the air enters the polluting aerosol (toluene), which is a toxic substance. The whole process of pollution is considered step by step, where at each stage the contaminating aerosol changes its parameters of properties. The result of the analysis of the pollution process is a physical model and mathematical dependence describing the essence of this process.
