TL;DR: It has been found that the small size and high surface area of NPs make them more toxic to organisms than microplastics, however, most of the current toxicological studies of NPS on freshwater organisms could not be simulated in real environment.

TL;DR: In this paper, the adsorption of an anionic surfactant sodium dodecyl sulfate (SDS) on negatively charged silica was studied to provide a better understanding of the anionic adaption phenomena in an electrostatic repulsion environment between SDS and soil.
Abstract: The adsorption of an anionic surfactant sodium dodecyl sulfate (SDS) on a negatively charged silica was studied to provide a better understanding of surfactant adsorption phenomena in an electrostatic repulsion environment between surfactant and soil. The adsorption experiment was conducted under different electrolyte concentration and pH. Results indicated that adsorption happened with hydrophobic interaction, although electrostatic repulsion was generated between SDS and silica surface. The adsorption amount decreased with decreasing electrolyte concentration and increasing pH due to the increase of electrostatic repulsion. The influence of electric potential near the silica surface on the adsorption was confirmed with the modified Langmuir adsorption equation, 1-pK basic Stern model and zeta potential. Because silica is ubiquitous in soils and the water environment, the adsorption characteristics of an anionic surfactant is important when we consider the fate of an anionic surfactant in the env...
