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

Abstract

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.

Three-Dimensional Biomass Composites Using the Maillard Reaction Products of Molasses as a Binder

“…Indeed, lignocellulosic biomass has been widely used to develop sorption materials for environmental and industrial purposes, because several hydrophilic and hydrophobic functional organic groups of lignin can be involved in several noncovalent interactions. Previous research on the physical interaction between coronavirus particles and microplastics indicates that a hydrophobic portion such as lignin’s benzene rings would be a causal factor for this sorption phenomenon …”

“…Previous research on the physical interaction between coronavirus particles and microplastics indicates that a hydrophobic portion such as lignin's benzene rings would be a causal factor for this sorption phenomenon. 39 The biodegradation rate of our composite under regular composting conditions was compared with that of cellulose that was easily transformed into CO 2 (Figure 6A). Molassesbased composite was shown to emit much less CO 2 than the cellulose, and at the end of composting, the CO 2 level was almost the same as that of the vials nontreated, indicating that biodegradation of molasses-based composite rarely occurred as the composting time increased (Figure 6B).…”

Effective stabilization of electrochemically prepared ecological oxidizing agent—ferrate(VI)—by encapsulation in zeolite and its application to water containing SARS‐CoV‐2 virus

“…Water samples were processed according to Belišová et al (2022). The pellets were then used for nucleic acid isolation using TRIzol reagent.…”
