Influence of Dissolution on Fate of Nanoparticles in Freshwater

Abstract—The fate of engineering nanoparticles (ENPs) determines how long they stay in a certain compartment such as freshwater. Many factors such as diameter of suspended particles in freshwater, depth of freshwater, may affect the fate of ENPs in freshwater with different extent. Dissolution rate (kdiss) of ENPs has been demonstrated as one of the most significant parameters. However, the influences of kdiss on relative importance of the other parameters are still not clear. In this study, the relative importance of four parameters has been calculated with the kdiss being fixed to eight different values respectively. The relative importance decreases along with the increasing kdiss values. The results are well fitted (R2 > 0.999) by an exponential associate function, which simplifies the calculation of the relative importance of the studied parameters.

Index Terms—Dissolution rate, fate model, nanoparticle, sensitivity analysis, exponential associate function.
