Perspective on the status and behaviour of SARS-CoV-2 in soil

Soil contamination by SARS-CoV-2 is highly probable because soil can collect several transporters of the virus, such as fallout aerosols, wastewaters, relatively purified sludges, and organic residues. However, the fate and status of SARS-CoV-2 in soil and the possible risks for human health through contaminated food are unknown. Therefore, this perspective paper discusses the challenges of determining the SARSCoV-2 in soil and the mechanisms concerning its adsorption, movement, and infectivity in soil, considering what has already been reported by perspective papers published up to May 2021. These issues are discussed, drawing attention to the soil virus bibliography and considering the chemical structure of the virus. The mechanistic understanding of the status and behavior of SARS-CoV-2 in soil requires setting up an accurate determination method. In addition, future researches should provide insights into i) plant uptake and movement inside the plant, ii) virus adsorption and desorption in soil with the relative infectivity, and iii) its effects on soil functions. Models should simulate spatial localization of virus in the soil matrix. (c) 2021 The Author(s). Published by Elsevier B.V. on behalf of King Saud University.

Automated summary

This paper discusses the challenges of determining the presence and impact of SARS-CoV-2 in soil, focusing on its adsorption, movement, and infectivity mechanisms. Future research should focus on plant uptake, virus adsorption and desorption in soil, and the effects on soil functions. Models should be developed to simulate the spatial localization of the virus in the soil.
