Modelling of concentration dynamics of fungal aerosols in the atmospheric boundary layer: I. Basic processes and equations

Fungi are the important allergens, pathogens of plants, animals and humans, as well as they produce toxins and are
agents of biodegradation of natural and artificial materials. The publication summarizes the relatively few theoretical and
experimental papers devoted modeling the the dynamics of bioaerosols in the surface layer of the atmosphere. The emphasis
is done on processes and quantitative regularities that are important for the calculation of the dynamics of fungal aerosol,
which consist of fungal spores and mycelial fragments of various diameters. We describe the key processes determining the
dynamics of bioaerosols in the surface layer of the atmosphere, namely: emission, gravitational sedimentation, turbulent
diffusion, washing by precipitations, particle collision, and a number of other processes. We carried out the formulation of
the problem, introduced a number of equations, describing the dynamics of bioaerosols in the surface layer of the
atmosphere, we discussed the boundary conditions, necessary to carry out the calculations.
