“…polyethylene PE, polystyrene PS, polypropylene PP) and biodegradable (polybutylene succinate PBS and polylactic acid PLA) polymers. In the case of work by Jiang et al in 2020, PBS was characterized to have a higher adsorption capacity than PE and PVC (around 2-fold compared to PE and 7-fold compared to PVC) [33]. Higher sorption capacity were also noted in the other works, more notably Concha-Graña et al [50] and Zuo et al [51].…”

Plastic pollution is and will be a problem for humanity to deal with for decades to come. The main cause for concern is plastic debris of microsizes, that has been detected in many worrying locations, e.g. human body. Microplastic can carry many substances. It’s possible for many substances, including toxins, to accumulate on plastic surface. This review pertains to the compilation of the newest scientific information regarding plastic’s ability to sorption. The methodological approach as well as mathematical models used in studies pertaining to this topic have been demonstrated. The type of plastic, the matrix and state of microplastic sample have been described to be affecting sorption on plastic. Some problems with methodology in compiled sorption studies have been outlined. It was concluded that more research is needed to be done to fully grasp this topic.

“…Previous studies have shown that DOM reduces the sorption capacity of organic contaminants on microplastics, which is mainly explained by DOM enhancing the co-solubilization of hydrophobic contaminants in the liquid phase. ,, Here, the eco-corona was confirmed to act as a barrier inhibiting the adsorption of organic contaminants on the surface of microplastics, which supports our hypothesis (iii). This is particularly relevant for smaller microplastics, as the smaller the size of the microplastic is, the larger the specific surface area for adsorption.…”

The eco-corona on microplastics refers to the initial layer of biomolecular compounds adsorbed onto the surface after environmental exposure. The formation and composition of the eco-corona in soils have attracted relatively little attention; however, the eco-corona has important implications for the fate and impacts of microplastics and co-occurring chemical contaminants. Here, it was demonstrated that the formation of the eco-corona on polyethylene microplastics exposed to water-extractable soil metabolites (WESMs) occurs quite rapidly via two pathways: direct adsorption of metabolites on microplastics and bridging interactions mediated by macromolecules. The main eco-corona components were common across all soils and microplastics tested and were identified as lipids and lipid-like molecules, phenylpropanoids and polyketides, nucleosides, nucleotides, and their analogues. WESMs were found to reduce the adsorption of co-occurring organic contaminants to microplastics by two pathways: reduced adsorption to the eco-corona surface and co-solubilization in the surrounding water. These impacts from the eco-corona and the soil metabolome should be considered within fate and risk assessments of microplastics and co-occurring contaminants.

“…Cluster #1, #3 and #5 were focused on the combined effects of micro(nano)plastic and other co-occurring contaminants in earthworms. Numerous studies have demonstrated that the small particle size and large specific surface area of micro(nano)plastics make them capable of absorbing ambient pollutants, such as heavy metals and hydrophobic organic chemicals (HOCs) [ 49 , 50 , 51 ]. Their combined toxicity has, therefore, been the focus of many scholars.…”

Micro(nano)plastics are emerging contaminants that have been shown to cause various ecotoxicological effects on soil biota. Earthworms, as engineers of the ecosystem, play a fundamental role in soil ecosystem processes and have been used as model species in ecotoxicological studies. Research that evaluates micro(nano)plastic toxicity to earthworms has increased greatly over the last decade; however, only few studies have been conducted to highlight the current knowledge and evolving trends of this topic. This study aims to visualize the research status and knowledge structure of the relevant literature. Bibliometrics and visualization analyses were conducted using co-citations, cooperation networks and cluster analysis. The results showed that micro(nano)plastic toxicity to earthworms is an emerging and increasingly popular topic, with 78 articles published from 2013 to 2022, the majority of which were published in the last two years. The most prolific publications and journals involved in this topic were also identified. In addition, the diversity of cooperative relationships among different countries and institutions confirmed the evolution of this research field, in which China contributed substantially. The high-frequency keywords were then determined using co-occurrence analysis, and were identified as exposure, bioaccumulation, soil, pollution, toxicity, oxidative stress, heavy metal, microplastic, Eisenia foetida and community. Moreover, a total of eight clusters were obtained based on topic knowledge clustering, and these included the following themes: plastic pollution, ingestion, combined effects and the biological endpoints of earthworms and toxic mechanisms. This study provides an overview and knowledge structure of micro(nano)plastic toxicity to earthworms so that future researchers can identify their research topics and potential collaborators.
