“…The pH can significantly affect the adsorption capacity of MPs to heavy metals. When pH is less than a certain value, MPs will not interact with heavy metals (Tang et al, 2020). Generally, increased pH level results in increased adsorption capacity for heavy metals (Guo et al, 2020); however, there are also different opinions (Zhang W. et al, 2020).…”

“…Commonly used adsorption models include pseudofirst-order kinetic model, pseudo-second-order kinetic model, Elovich kinetic model, Boyd model, Weber-Morris Model, and Bangham channel diffusion model. The adsorption process was usually fitted with a pseudo first-order kinetic model (Zhang et al, 2018;Zon et al, 2018); however, some researchers also reported that the pseudo-second-level kinetic model can yield a better fit (Nethaji et al, 2013;Taha et al, 2016;Oz et al, 2019;Guo et al, 2020;Tang et al, 2020). This model assumes that the adsorption of heavy metals by MPs is mainly controlled by the chemisorption mechanism, involving the sharing or transfer of electron pairs, and is not controlled by the material transport step.…”

Microplastics (MPs), tiny particles broken down from larger pieces of plastics, have accumulated everywhere on the earth. As an inert carbon stream in aquatic environment, they have been reported as carriers for heavy metals and exhibit diverse interactive effects. However, these interactions are still poorly understood, especially mechanisms driving these interactions and how they pose risks on living organisms. In this mini review, a bibliometric analysis in this field was conducted and then the mechanisms driving these interactions were examined, especially emphasizing the important roles of microorganisms on the interactions. Their combined toxic effects and the potential hazards to human health were also discussed. Finally, the future research directions in this field were suggested. This review summarized the recent research progress in this field and highlighted the essential roles of the microbes on the interactions between MPs and heavy metals with the hope to promote more studies to unveil action mechanisms and reduce/eliminate the risks associated with MP presence.

“…The core collection of WOS was used as the source database, with the retrieval formula: TS = ("Micro plastic*") or (TS = "micro-plastic*") or (TS = microplastic*); the language was chosen as "English" and the literature type was "article". In 2004, Thompson et al (2004) from the University of Plymouth suggested the concept of "micro plastics" for the rst time. Therefore, the research period was selected as 2004-2020.…”

“…MPs, which are plastic particles with diameters less than 5 mm (Thompson et al, 2004), have been frequently detected in a variety of environments, including the oceans (Andrady, 2011), surface water (Mintenig et al, 2020) sediment (Corcoran et al, 2020;Mani et al, 2019), air Wright et al, 2020) soil (Xu et al, 2019) and even in drinking water (Koelmans et al, 2019). Additionally, MPs were also considered as a carrier that can adsorb other contaminants, including traditional organic pollutants and heavy metals (Engler, 2012;Seidensticker et al, 2018;Sharma et al, 2020;Tang et al, 2020;. Therefore, MPs pollution will cause complicated environmental impacts and increased ecological risks, and more attention should be paid to this issue.…”

Microplastics (MPs) pollution has garnered significant interest as a serious environmental problem. To date, a large amount of research has been published on this topic. We analyzed the related studies to assess the global developments of MPs regarding the evolution, research trends, and hotspots by bibliometric. A total of 2,872 bibliographic records were retrieved from the Web of Science Core Collection, and CiteSpace 5.4 was used for bibliometrics. The results visually displayed the contributing countries, institutions, authors, keywords, and potential research directions in the MPs fields. The scientific developments in this field began in 2004 and have accelerated considerably since 2012. China and the USA are the leading countries in MPs research. The research on MPs is multidisciplinary and involves Ecology, Chemistry, Molecular Biology, Environmental Science, and Oceanography. Among these, Oceanography was the most connected with MPs and was the most well-developed. Overall, we mapped the development of MPs research and attempted a comprehensive discussion and understanding of scientific advances, as well as the progress made.
