A Stochastic Model for Transport of Particulate Matter in Air: An Asymptotic Analysis
Source: Acta Applicandae Mathematicae, Volume 59, Number 1, October 1999 , pp. 21-43(23)
A branching particle system with changes of size is considered as a model for transport of particulate matter in air. This type of model is motivated by problems arising in the context of air pollution. High-density fluctuation limits for the process recording the positions and sizes of the particles through time are presented. These results allow to compute approximate probabilities for the temporal and spatial concentrations of particles of given sizes (in particular the small-sized pollutant particles which pose a health hazard).
