“…The effect of photo-oxidation on the adsorption behavior of MNPs is studied using batch adsorption experiments by determining adsorption kinetics and adsorption isotherms. The Langmuir and Freundlich models are the most commonly used models to describe adsorption of contaminants on pristine and aged MNPs, indicating mono- or multilayer adsorption processes on heterogeneous surfaces. ,, The influence of photo-oxidation on the adsorption behavior of contaminants on MNPs mainly depends on three mechanisms (Figure ): (1) the increase in surface roughness and SSA of aged MNPs could provide more adsorption sites for contaminants, , (2) decreased hydrophobicity and increased O-containing functional groups can change adsorption affinity of contaminants to MNPs mediated by hydrophobic or hydrophilic interaction, , and (3) increased electronegativity of aged MNPs could influence the electrostatic interaction between MNPs and charged OPs and HMs. , …”

“…Currently, several reviews have summarized the weathering processes of MPs and corresponding effects on the environmental behavior of MPs, mainly considering the different weathering processes and mechanisms, and the effect of weathering on the properties, adsorption, and toxicity of MPs. ,− However, few of them have thoroughly considered the physical, chemical, and biological effects of photo-oxidation of MNPs in the environment. In the last two years, an increasing number of studies have focused on understanding the process of photo-oxidation and its impact on different types of MNPs, as well as the effect of environmental constituents on this process. ,,,− Furthermore, research on the influence of photo-oxidation of MNPs on the adsorption and photochemical transformation of other pollutants has gained more attention. − The biological effect of photo-oxidized MNPs on organism activity, especially microbial community composition and function has also become a subject of interest among scholars. ,, More importantly, the photo-oxidation process and the physical, chemical, and biological behavior of MNPs are mutually associated and inseparable. Thus, it is necessary to give a critical review of recent research on the physical, chemical, and biological effects of photoaged MNPs in aquatic and terrestrial environments.…”

Micro-and nanoplastics (MNPs) are attracting increasing attention due to their persistence and potential ecological risks. This review critically summarizes the effects of photo-oxidation on the physical, chemical, and biological behaviors of MNPs in aquatic and terrestrial environments. The core of this paper explores how photo-oxidation-induced surface property changes in MNPs affect their adsorption toward contaminants, the stability and mobility of MNPs in water and porous media, as well as the transport of pollutants such as organic pollutants (OPs) and heavy metals (HMs). It then reviews the photochemical processes of MNPs with coexisting constituents, highlighting critical factors affecting the photo-oxidation of MNPs, and the contribution of MNPs to the phototransformation of other contaminants. The distinct biological effects and mechanism of aged MNPs are pointed out, in terms of the toxicity to aquatic organisms, biofilm formation, planktonic microbial growth, and soil and sediment microbial community and function. Furthermore, the research gaps and perspectives are put forward, regarding the underlying interaction mechanisms of MNPs with coexisting natural constituents and pollutants under photo-oxidation conditions, the combined effects of photo-oxidation and natural constituents on the fate of MNPs, and the microbiological effect of photoaged MNPs, especially the biotransformation of pollutants.

“…Jiang et al found that the aging mode would significantly affect the surface structure, hydrophobicity, surface charge, and concentration of oxygencontaining functional groups of MPs, resulting in differences in the adsorption characteristics of SAs on MPs. 9 However, the aging behavior of MPs is inevitable in the natural environment. It has been reported that MPs were found widely distributed in major freshwater systems and even were detected in the drinking water all over the world.…”

Microplastics pollution in the aquatic environment has been considered as a particular concern for global ecosystems in recent years. Herein, bleached eucalyptus pulp was chemically modified by 2,2,6,6-tetramethylpiperidine-1-oxyl and 2,3-epoxypropyltrimethylammonium chloride to produce modified cellulose nanofibrils (CNFs). Then, porous CNF-based aerogels were prepared by the freeze-drying process and selected as a matrix filter for highly efficient separation of polystyrene microplastics (PSMPs). Results showed that the modified CNF aerogels could efficiently separate different types of PSMPs with filtration efficiencies of 100 and 75% for carboxylate-modified polystyrene (PS–COOH) and amine-modified polystyrene (PS–NH2), respectively. Meanwhile, the hydrophilicity and porous structure of these materials endowed aerogels with high filtration flux. The excellent filtration performance of materials mainly relied on their microstructure and high surface charge, which could effectively capture and separate PSMPs from aqueous solution through the synergistic actions of physical entrapment, electrostatic interaction, and hydrogen bonding. In addition, the modified aerogels had good stability and reusability, and the filtration efficiency of PS–COOH remained at 100% after eight cycles. These findings provide a green and promising method for designing functional aerogel filters from sustainable resources to be used for applications in microplastics separation and water purification.

Microplastics (MPs) can act as carriers of environmental arsenic species into the stomach with food and release arsenic species during digestion, which threatens human health. Herein, an integrated dynamic stomach model (DSM)-capillary electrophoresis-inductively coupled plasma mass spectrometry (CE-ICPMS) is developed for online monitoring of the release and transformation behaviors of arsenic species loaded on MPs (As-MPs) in the simulated human stomach. The 3D-printed DSM with a soft stomach chamber enables the behaviors of gastric peristalsis, gastric and salivary fluid addition, pH adjustment, and gastric emptying (GE) to be controlled by a self-written program after oral ingestion of food with As-MPs. The gastric extract during digestion is introduced into the spiral channel to remove the large particulate impurity and online filtered to obtain the clarified arsenic-containing solution for subsequent speciation analysis of arsenic by CE-ICPMS. The digestion conditions and pretreatment processes of DSM are tracked and validated, and the release rates of As-MPs digested by DSM are compared with those digested by the static stomach model and DSM without GE. The release rate of inorganic arsenic on MPs is higher than that of organic arsenic throughout the gastric digestion process, and 8% of As(V) is reduced to As(III). The detection limits for As(III), DMA, MMA, and As(V) are 0.5−0.9 μg L −1 using DSM-CE-ICPMS, along with precisions of ≤8%. This present method provides an integrated and convenient tool for evaluating the release and transformation of As-MPs during human gastric digestion and provides a reference for exploring the interactions between MPs and metals/metalloids in the human body.
