“…The microplastics or microfibers produced by the various washing processes can thus influence the concentration of viral particles in the sewerage system. The surface of microplastic and microfibers allows the adherence and colonization of microfibers, bacteria, and viruses also [ 28 ] because of their physic-cal porous structure, which can cause the transmittal pathogenic microorganisms [ 29 ]. According to the authors [ 30 , 31 ].…”

The research aims at washing processes as possible sources of microplastics, specifical microfibers in wastewater, and the behavior of the virus particles SARS-CoV-2 in wastewater after the washing process as well as their ability to sorb to the surface of microfibers, released from washing processes. The conclusions of the research point to the ability of the virus to attach to possible solid impurities such as textile fibers (microfibers) occurring in the sewer and to the ability of wash water to influence their possible occurrence in the sewer. The highest efficiency (more than 99%) of removal virus particles was after washing process, using liquid washing powder, and washing soda. These findings may gradually contribute to a better understanding of the behavior of the virus particles in the sewer.

“…In an air sample monitoring study conducted near a hospital complex in Sao Paulo, Brazil, MPs were found in the forms of airborne particles ranging from nil to 0.9 unit·m −3 as well as fibers in the range of 9–24 unit·m −3 . The presence of these MP in the air can be a potential carrier of the virus, including SARS-CoV-2 aerosols, facilitating virus entry into the human body ( Amato-Lourenço et al, 2022 ). Hence, the fate of MPs released from pandemic-related plastic waste should be investigated not only in the terrestrial or marine environment but also in the atmosphere.…”

“…In such cases, MPs become the carriers of pollutants or pathogens for their quickly invading against our bodies. Recently finding reported the content of SARS-CoV-2 has a significant positive correlation with MPs in the aerosol collected near a medical center in Latin America with unknown consequences ( Amato-Lourenco et al, 2022b ). They imply that air source MPs may become the carriers of SARS-CoV-2 for their spreading and transmission in the current COVID-19 pandemic.…”

Most disposable plastic products are degraded slowly in the natural environment and continually turned to microplastics (MPs) and nanoplastics (NPs), posing additional environmental hazards. The toxicological assessment of MPs for marine organisms and mammals has been reported. Thus, there is an urgent need to be aware of the harm of MPs to the human immune system and more studies about immunological assessments. This review focuses on how MPs are produced and how they may interact with the environment and our body, particularly their immune responses and immunotoxicity. MPs can be taken up by cells, thus disrupting the intracellular signaling pathways, altering the immune homeostasis and finally causing damage to tissues and organs. The generation of reactive oxygen species is the mainly toxicological mechanisms after MP exposure, which may further induce the production of danger-associated molecular patterns (DAMPs) and associate with the processes of toll-like receptors (TLRs) disruption, cytokine production, and inflammatory responses in immune cells. MPs effectively interact with cell membranes or intracellular proteins to form a protein-corona, and combine with external pollutants, chemicals, and pathogens to induce greater toxicity and strong adverse effects. A comprehensive research on the immunotoxicity effects and mechanisms of MPs, including various chemical compositions, shapes, sizes, combined exposure and concentrations, is worth to be studied. Therefore, it is urgently needed to further elucidate the immunological hazards and risks of humans that exposed to MPs.
