A review on microplastic fibers and beads in wastewater: The current knowledge on their occurrence, analysis, treatment, and insights on human exposure impact
Summary
This review focuses specifically on microfibers and microbeads, the two most relevant microplastic shapes found in wastewater, covering their sources, detection methods, and health implications. Researchers found that conventional wastewater treatment plants are not designed to effectively remove these particles, allowing them to re-enter the environment. The study highlights significant gaps in our understanding of how these specific microplastic shapes affect human health and ecosystems.
The persistent presence of microplastic (MP) pollution in conventional wastewater treatment plants (WWTPs) is observed worldwide as they are currently not designed to remove MPs effectively. This pollution eventually re-enters and circulate in the environment, elevating the risks posed to ecosystems and organisms through biotoxicity and ecological destabilization. The most common MP shape in wastewater are microfibers (MFs) yet focused comprehensive studies on MFs is limited. Although not as abundant as MFs, microbeads (MBs) are also an important shape in WWTPs as they were among the first shapes to be targeted for production regulation, highlighting their significant impacts. Targeting these specific shapes are crucial as they represent the foundational components of wastewater MP pollution, and the current lack of these studies hinders our ability to address MP persistence and mitigation and management strategies properly. Therefore, this review aims to present the most up-to-date information on the distribution of MFs and MBs across WWTPs. Specifically, the source, detection, and analysis of MFs and MBs in wastewater, physicochemical characterization and interactions of common MF/MB polymers, and the current efforts to mitigate the production and release of these shaped MPs are summarized. This is the first literature review to focus on MFs and MBs in the aspects of their source, human toxicity, detection, and analysis in wastewater.

Microplastic contamination in wastewater: Sources, distribution, detection and remediation through physical and chemical-biological methods
This review covers how microplastics end up in wastewater from sources like textile fibers, personal care microbeads, and broken-down plastic debris, and how they often survive the treatment process. Current removal methods like filtration and chemical degradation are costly and not fully effective. The lack of standardized ways to measure microplastics in wastewater makes it difficult to assess the full scope of human exposure through water systems.
Detection and Characterisation Techniques for Microfiber in Wastewater
This review covers current detection and characterization techniques for microfibers, the most common type of microplastic found in the environment. Researchers discuss how microfibers are released in large quantities during home laundry and enter waterways through wastewater treatment plants. The study emphasizes that precise detection methods are essential for understanding and controlling microfiber pollution, given its harmful effects on both aquatic ecosystems and human health.
Characterization and Removal of Microplastics in Different Stages of Wastewater Treatment Plants
This review examines the types, shapes, and sizes of microplastics found in domestic and industrial wastewaters and evaluates the removal efficiency of different treatment processes across wastewater treatment plant stages, noting that no existing process achieves 100% removal.
Microfibres from Textile Industry Effluents
Researchers reviewed the fate of microfibres released from textile industry effluents, finding that conventional wastewater treatment is insufficient to fully remove fibres, which then enter receiving waterways and contribute to environmental microplastic loads.
Microplastics in Wastewater Treatment Plants: Characteristics, Occurrence and Removal Technologies
This review summarizes how wastewater treatment plants are a major pathway for microplastics entering the environment, covering the types, sizes, and sources of microplastics found in wastewater. While treatment plants can remove many microplastics, significant amounts still escape into rivers and oceans through treated water and sludge. The authors evaluate various removal technologies and recommend advanced treatment methods to better prevent microplastics from reaching water supplies.
