Transport of NPs through environment partition is the most critical parameter to evaluate NPs impact, expecting high mobility of NPs that are designed to be released into the environment . Transport and, therefore, NPs mobility are determined by forces, such as London-van der Waals and double-layer forces that are responsible for attachment.
