Particle resuspension: A review

Published numerical values of resuspension variables, rates, factors, and weathering half-lives are summarized. Results of the review show the great uncertainty in accurately predicting resuspension. Resuspension rates range over six orders of magnitude from 10^?12 to 10^?4 fraction/sec, resuspension factors over nine orders of magnitude from 10^?10 to over 10^?2 m^?1, and weathering half-lives from 35 days to years. Data are yet needed to evaluate resuspension changes as a function of pollutant particle properties, including chemical composition, solubility, and shape.
