Summary: Microplastic contamination is widespread in aquatic environments, with increasing plastic production leading to a rise in microplastic pollutants released into the environment. These plastic particles can absorb various chemical pollutants and contribute to toxin accumulation in the food chain. This study investigated the adsorption behavior of aniline, a priority environmental pollutant, on polystyrene microplastics (mPS). The results showed that mPS had a maximum adsorption capacity of 0.060 mg/g, with equilibrium reached after 24 hours. The adsorption kinetics followed a pseudo-second-order model and the Freundlich model described the adsorption isotherms. The adsorption mechanisms may involve 7C-7C interactions and hydrophobic interactions. Factors such as pH, ionic strength, and temperature of the solution played significant roles in the adsorption process.

Summary: In recent years, there has been increasing worldwide attention on the adsorption of heavy metals on microplastics (MPs), which are emerging carriers for environmental pollutants. However, the understanding of heavy metal adsorption on biodegradable MPs in estuarine environments is still limited. This study investigated the aging of biodegradable and conventional MPs in the Pearl River Estuary after long-term exposure and their impacts on heavy metal adsorption from seawater. The results showed that both types of MPs could adsorb heavy metals, with fluctuating adsorption capacities on different MPs and exposure times. The aging characteristics of MPs played a significant role in heavy metal adsorption, accounting for 51.0% of the contribution, while environmental factors only contributed to 13.2%.

Summary: This study investigated the adsorption kinetics, isotherm and influencing factors of 17β-estradiol (E2) on three dominant microplastics, as well as analyzed the adsorption mechanism using molecular dynamics simulation. The results showed that E2 adsorption onto microplastics followed Pseudo-second-order kinetics and Redlich-Petersen isotherm model. The adsorption capacity of E2 on microplastics was polyethylene (PE) > polypropylene (PP) > polystyrene (PS). The small particle size of microplastics facilitated the adsorption due to its large specific surface area. Thermodynamic parameters indicated that the adsorption of E2 was a spontaneous and exothermic process, with low temperature being beneficial for adsorption. MD simulation confirmed that E2 adsorption on microplastics belonged to surface adsorption, consistent with experimental results.

Summary: There is a growing concern about plastic pollution and its impact on both health and ecology. This study investigated the release of di-2-ethylhexyl phthalate (DEHP), a common plastic additive, from different types of plastics into seawater. The results showed that the leaching potentials of DEHP varied among the selected plastics, with polyethylene mulch having the highest leaching potential and PBAT/PLA bags having the lowest. The study also assessed the potential environmental and human exposure risk of the leached DEHP, indicating low pollution risks in seawater.

Summary: This review comprehensively summarized the interaction characteristics and mechanisms between microplastics and antibiotics, with a particular emphasis on the weathering properties of microplastics and the growth of attached biofilm. The study found that aged microplastics usually adsorb more types and quantities of antibiotics from aquatic environments compared to virgin microplastics, and the attached biofilm can further enhance adsorption capacities and biodegrade some antibiotics. This research fills the knowledge gaps of the interaction between microplastics and antibiotics, provides basic information for evaluating their combined toxicity, reveals the distribution of both emerging pollutants in the global water chemical cycle, and informs measures to remove microplastic-antibiotic pollution.

Summary: This study investigated the distributions, influential factors, and ecological risks of 15 phthalate acid esters (PAEs) in the sediments of three typical lakes in Inner Mongolia. The results showed that PAEs were widespread in surface sediments, with highest concentrations in lakes with higher population density and anthropogenic activities. The cold climate explained the higher abundance of DEP in sediments from lakes at higher latitudes. Most PAEs were terrestrial pollutants, and highest PAE concentrations were found at discharge river estuaries. PAE concentrations in core sediments increased with years and fluctuated due to PAE usage and input. Risk assessment indicated that DIBP and DEP posed high risks to sensitive fish.

Summary: This study investigated the combined adsorption/desorption of antibiotics and heavy metals on aged microplastics. The results showed that the specific surface area of aged microplastics increased, and the adsorption capacities of antibiotics and heavy metals were higher on aged microplastics compared to pristine microplastics. The adsorption of antibiotics on microplastics was minimally affected by heavy metals, while heavy metal adsorption was slightly enhanced by antibiotics at pH 8.0. The adsorption capacities of antibiotics and heavy metals reached their maximum at pH 5.0 or 6.0 and decreased thereafter, with the highest level of heavy metal adsorption at approximately pH 6.0. The desorption rates of antibiotics and heavy metals were lower from aged microplastics compared to pristine microplastics.

Summary: Microplastics act as sources and vectors of organic contaminants in the environment, raising concerns for potential harmful impacts on the environment, biota, and human health. Microplastic particles exhibit a higher affinity for hydrophobic organic contaminants underwater. However, the concentrations of organic contaminants adsorbed on microplastic surfaces and their distribution are greatly influenced by environmental factors and physicochemical properties in aquatic environments.

Summary: Phthalate esters (PAEs) are widely produced and used in China as endocrine disruptors, with a significant amount entering aquatic systems annually. A study in Poyang Lake found that concentrations of PAEs nearly doubled in the dry season compared to the wet season, with DBP and DEHP being the most abundant congeners. The ecological risk assessment revealed that while DEP and BBP posed no risk in the lake, DBP had a potential risk and DEHP had an unacceptable risk that requires further action.

Summary: This study investigated the leaching behavior of phthalate plasticizer from polyvinyl chloride (PVC) microplastics and found that plastic properties had a significant impact on the release of plasticizer, while environmental factors had a minor influence. Fulvic acid was found to greatly promote phthalate release, suggesting that it can enhance phthalate solubility and solution-plastic affinity. Additionally, the coexistence of fulvic acid and NaCl resulted in more phthalate leaching, indicating a potential role of other fulvic acid-like additives in the leaching process.

Summary: The large-scale use of polytetrafluoroethylene has led to increased amounts of polytetrafluoroethylene (PTFE) microplastic particles entering the environment. The interaction between PTFE and arsenic (As(III)) in water in the presence of humic acid (HA) and fulvic acid (FA) needs to be urgently investigated due to pollution in the environment. PTFE forms pi complexes with HA units, which increases the number of oxygen-containing functional groups on its surface, ultimately enabling the adsorption of As(III).
