Sorption of SARS-CoV-2 Virus Particles to the Surface of Microplastics Released during Washing Processes

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.

Automated summary

The research investigates washing processes as potential sources of microplastics, specifically microfibers in wastewater, and explores the behavior of SARS-CoV-2 virus particles in wastewater after the washing process, particularly their ability to adsorb onto the surface of released microfibers. The study concludes that the virus can attach to solid impurities such as textile fibers (microfibers) found in sewage, and that the wash water can influence their presence in wastewater. The highest efficiency (over 99%) of virus particle removal was observed after the washing process using liquid washing powder and washing soda. These findings contribute to a better understanding of the behavior of virus particles in wastewater.
