Review of resuspension models. [Particle resuspension]
Resuspension of particles is classified, according to the prominent path of exposure and the type of consideration involved in estimating concentrations, as general resuspension, local resuspension, and transfer resuspension. General resuspension can be driven by winds or mechanical disturbances while local resuspension and transfer resuspension are primarily caused by mechanical disturbances. Modeling techniques consist of the resuspension factor, the resuspension rate and mass-loading. For general resuspension the resuspension rate is preferred while the resuspension factor or mass-loading approach can be used for local resuspension. Data for estimation of transfer resuspension are not really adequate to even make a first approximation as to its importance. Resuspension of contaminants on the ground leading to inhalation is generally assumed to be an important pathway of exposure to people. Methods of calculation for prediction of this pathway (models) are used widely in Environmental Impact Statements, risk assessments, and derivation of standards.
