Review of resuspension models

Resuspension 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
