Abstract

Geosorbents are the main host of anthropogenic organic pollutants and play a vital role in their fate and transport in the natural environment. Soil and sediment are the most common and abundant geosorbents in the natural environment; their interactions with organic pollutants, especially sorption and desorption processes, have been extensively studied from the perspectives of thermodynamics and kinetics. Recently, the aging of organic pollutants in geosorbents has drawn increased attention, leading to an improved understanding of interactions between organic pollutants and geosorbents and informing remediation criteria. Aging has been deemed important in accurately assessing ecologic and health risks of organic pollutants, and both positive and negative impacts have been reported in studies of natural and artificial sorbents. This paper summarizes recent research progress on organic pollutant aging in geosorbents, including related mechanism research, influence factors, bioavailability assessments, and biological and physicochemical remediation of aged organic pollutants. We also discuss issues in the current research and bring forward suggestions for future study.
