ClearAdsorption behavior of organic pollutants and metals on micro/nanoplastics in the aquatic environment
This review examines how micro- and nanoplastics in aquatic environments adsorb organic pollutants and metals onto their surfaces, effectively acting as carriers for other contaminants. Researchers found that environmental factors like pH, salinity, and aging of the plastic significantly influence this sorption behavior. The findings raise concerns that microplastics may increase the bioavailability and toxicity of chemical pollutants in waterways.
Adsorption behaviour and interaction of organic micropollutants with nano and microplastics – A review
This review analyzed the adsorption behavior of organic micropollutants — including pharmaceuticals, pesticides, and industrial chemicals — onto nano- and microplastics, finding that adsorption is governed by pollutant hydrophobicity, particle surface area, and aging state, and that microplastics can act as vectors delivering co-contaminants to aquatic organisms.
Interactions of microplastics and soil pollutants in soil-plant systems
This review synthesized literature on microplastic interactions with organic pollutants and heavy metals in the soil-plant system, covering sorption mechanisms, distribution characteristics, and transfer to crops. Microplastics were found to both adsorb and desorb contaminants depending on environmental conditions, acting as both concentrators and dispersal agents for soil pollutants.

Micro(nano)plastics: Unignorable vectors for organisms
This review examines the role of micro- and nanoplastics as vectors for contaminants — including heavy metals, organic pollutants, and pathogens — in aquatic and terrestrial environments. It synthesizes evidence on how plastic particles can adsorb, transport, and release harmful substances, amplifying their ecological and health risks beyond the physical effects of the particles alone.
Effect of microplastics on the environmental behavior of emerging contaminants in aquatic matrices
This study examines how microplastics affect the environmental behavior of emerging contaminants in aquatic systems. Microplastics can adsorb other pollutants and alter their bioavailability, potentially increasing or decreasing toxic effects depending on the chemicals and environmental conditions.
Adsorption of some hazardous aromatic hydrocarbons by various pristine and heat-activated aged microplastics as potential pollutant carriers in aquatic environment
Researchers examined how pristine and heat-aged microplastics of four polymer types adsorb hazardous aromatic hydrocarbons, finding that aging significantly altered adsorption capacity. The results demonstrate that weathered microplastics may act as more effective pollutant vectors than pristine particles in aquatic environments.
Transport of persistent organic pollutants: Another effect of microplastic pollution?
This review examines how microplastics act as vectors for persistent organic pollutants (POPs) in aquatic environments, covering the physical and chemical factors governing pollutant adsorption and desorption. The authors discuss how interactions between microplastics and POPs vary with polymer type, particle properties, and environmental conditions, and when these interactions may result in toxic effects on aquatic organisms.
Environmental behaviors of microplastics in aquatic systems: A systematic review on degradation, adsorption, toxicity and biofilm under aging conditions
Aging processes like UV irradiation and physical abrasion alter microplastic surface properties, increasing their capacity to adsorb environmental pollutants while also enhancing leaching of toxic additives like phthalates, collectively amplifying the environmental toxicity of weathered microplastics.
Effects of Weathering on Microplastic Dispersibility and Pollutant Uptake Capacity
This study examined how environmental weathering changes the surface properties of microplastics and their ability to absorb co-pollutants, finding that weathered MPs bind more contaminants than pristine particles due to surface oxidation and cracking. The results emphasize that the environmental fate and toxicity of microplastics change dynamically as they age in the environment.
