“…Further, the disposal of PPE kits and other routine items to the environment poses a serious threat. Recent studies have confirmed the presence of SARS-CoV-2 in wastewater ( Conde-Cid et al, 2021 ), which are prone to be transmitted in the soils ( Conde-Cid et al, 2020 ; Núñez-Delgado, 2020 ) and further back to the ecosystem ( Cela-Dablanca et al, 2021 ). Hence it is essential to sterilize the contacting surfaces before their disposal to the environment.…”

SARS-CoV-2 virus and other pathogenic microbes are transmitted to the environment through contacting surfaces, which need to be sterilized for the prevention of COVID-19 and related diseases. In this study, a prototype of a cost-effective sterilization box is developed to disinfect small items. The box utilizes ultra violet (UV) radiation with heat. For performance assessment, two studies were performed. First, IgG (glycoprotein, a model protein similar to that of spike glycoprotein of SARS-COV-2) was incubated under UV and heat sterilization. An incubation with UV at 70 °C for 15 minutes was found to be effective in unfolding and aggregation of the protein. At optimized condition, the hydrodynamic size of the protein increased to ∼171 nm from ∼5 nm of the native protein. Similarly, the OD 280 values also increased from 0.17 to 0.78 indicating the exposure of more aromatic moieties and unfolding of the protein. The unfolding and aggregation of the protein were further confirmed by the intrinsic fluorescence measurement and FTIR studies, showing a 70% increase in the β-sheets and a 22 % decrease in the α-helixes of the protein. The designed box was effective in damaging the protein’s native structure indicating the effective inactivation of the SARS-COV-2. Furthermore, the incubation at 70 °C for 15 minutes inside the chamber resulted in 100 % antibacterial efficacy for the clinically relevant E.coli bacteria as well as for bacteria collected from daily use items. It is the first detailed performance study on the efficacy of using UV irradiation and heat together for disinfection from virus and bacteria.

“…Another component of transmission is water runoff to the soil, where wastewater treatment is lacking. Untreated wastewater is used directly to irrigate the soil, or it may cause indirect diffusion of the soil near the water flow ( Conde-Cid et al, 2020 ). Some studies are investigating the detection and quantification of SARS-CoV-2 in sewage sludge, which provides an approach to estimate changes in COVID-19 prevalence on a population level ( Peccia et al, 2020 ).…”

“…Similarly, the soil environment has gained little attention with few reports on the presence and survival of the viruses in the soil or any connection ( Conde-Cid et al, 2020 ; Khan et al, 2021 ). Often, the wastewater and sewage sludge are disposed into the soil without proper treatment, while the sludge has the potential of harboring viruses if not properly treated.…”

The recent spread of severe acute respiratory syndrome coronavirus (SAR-CoV-2) and the accompanied coronavirus disease 2019 (COVID-19) has continued ceaselessly despite the implementations of popular measures, which include social distancing and outdoor face masking as recommended by the World Health Organization. Due to the unstable nature of the virus, leading to the emergence of new variants that are claimed to be more and rapidly transmissible, there is a need for further consideration of the alternative potential pathways of the virus transmissions to provide the needed and effective control measures. This review aims to address this important issue by examining the transmission pathways of SARS-CoV-2 via indirect contacts such as fomites and aerosols, extending to water, food, and other environmental compartments. This is essentially required to shed more light regarding the speculation of the virus spread through these media as the available information regarding this is fragmented in the literature. The existing state of the information on the presence and persistence of SARS-CoV-2 in water-food-environmental compartments is essential for cause-and-effect relationships of human interactions and environmental samples to safeguard the possible transmission and associated risks through these media. Furthermore, the integration of effective remedial measures previously used to tackle the viral outbreaks and pandemics, and the development of new sustainable measures targeting at monitoring and curbing the spread of SARS-CoV-2 were emphasized. This study concluded that alternative transmission pathways via human interactions with environmental samples should not be ignored due to the evolving of more infectious and transmissible SARS-CoV-2 variants.
