“…In the last decade, several scientific reports have been published describing the fate and effects of microplastics in not only marine but also freshwater ecosystems [1][2][3][4][5]. Plastic particles that are used as raw materials or additives in personal care products, such as peelings and shower gels, are primary microplastics [5][6][7][8]. Secondary microplastics, on the other hand, are a more diverse group and include particles formed as a result of manufacturing processes in industries, laundry in households, and the photodegradation or mechanical grinding of larger pieces in the environment [6].…”

This study evaluated the uptake of secondary nano- and small microparticles by the protozoan Spirostomum ambiguum, comparing edible (baker’s yeasts) and inedible (red latex) particles. Secondary nano- and microplastic particles were prepared from household materials made of four different polymers and served to the protozoans separately and as two-component mixtures in different proportions. The number and content of food vacuoles formed by the protozoan were analyzed using a digital microscope. The microscopic results showed that the protozoans ingested the secondary microplastic particles to a similar degree as the latex microspheres but to a lesser extent compared to the nutritional food—baker’s yeasts. At the microplastic concentrations of 1000 and 10,000 particles mL–1, no food vacuoles were observed inside the cells, which may be a finding of great ecological importance. In the protozoans served two-component mixtures, both microplastics and yeasts were found in the vacuoles formed by the organisms. The egestion of two-component vacuoles by the protozoans was slower than that of vacuoles containing a single component.

“…The common response to MP exposure includes oxidative stress, inflammation, metabolism disruption, cytotoxicity, and translocation to other tissues (Rahman et al, 2021;Wang et al, 2021b). Due to the persistent nature of MPs, the living organisms might also get long-term exposure to ingested MPs, which can lead to chronic responses, such as necrosis, compromised immune function, and reproductive and developmental damage (Smith et al, 2018;Yin et al, 2021). The effects of chronic exposure to MPs appear to be very variable, depending on the exposure level and individual susceptibility.…”

Interactions Between Microplastics and Heavy Metals in Aquatic Environments: A Review

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.

“…However, a threshold limit of 1000 nm is used in some studies related to environmental nanotechnology [17,18]. As discussed in a comprehensive review by Yin et al [19] on the toxicity of microplastics and nanoplastics, depending on the target organs, microplastics and nanoplastics show different toxicity. Microplastics with small sizes are more toxic than large ones because of the higher bioavailability and retention time in the body.…”

Separation and removal of microplastic pollution from aquatic environments as a global environmental issue is classified as one of the major concerns in both water and wastewater treatment plants. Microplastics as polymeric particles less than 5 mm in at least one dimension are found with different shapes, chemical compositions, and sizes in soil, water, and sediments. Conventional treatment methods for organic separation have shown high removal efficiency for microplastics, while the separation of small microplastic particles, mainly less than 100 µm, in wastewater treatment plants is particularly challenging. This review aims to review the principle and application of different physical and chemical methods for the separation and removal of microplastic particles from aquatic environments, especially in water treatments process, with emphasis on some alternative and emerging separation methods. Advantages and disadvantages of conventional separation techniques such as clarification, sedimentation, floatation, activated sludge, sieving, filtration, and density separation are discussed. The advanced separation methods can be integrated with conventional techniques or utilize as a separate step for separating small microplastic particles. These advanced microplastic separation methods include membrane bioreactor, magnetic separation, micromachines, and degradation-based methods such as electrocatalysis, photocatalysis, biodegradation, and thermal degradation.
