Abstract Description of 2 mathematical models used to determine the distribution of air pollutants, an indispensable parameter for the design of an appropriate ventilation system. The first model, in the form of a complex polynomial based on spatial network theory, takes account of the interaction between the different emission sources. The second, a system of differential equations resulting in an algorithm, expresses the influence of the air movement due to the ventilation on the distribution of dust concentration in a closed space. The results obtained by applying these models confirm the possibility of a mathematical representation of the phenomena that are involved in the propagation of pollutants in the air of production workplaces.
