“…This should be noted that some surface materials may better support the survival, persistence, and transmission of this virus ( Jiang et al, 2020a , b ). Findings of similar studies that are in agreement with the results of the present study, reveal that among the various contaminated environmental surfaces, hallway floors and door handles are the most infected surfaces regarding the presence of the viral RNA of the SARS-CoV-2 ( Mouchtouri et al, 2020 ; Dargahi et al, 2021 ). Nevertheless, the role of environmental conditions such as temperature and RH is significant and should be considered.…”

“…There are different mechanisms and routes of transmission for SARS-CoV-2 including the direct route (person-to-person transmission that occurs by having close and prolonged contact with a patient or an infected person) and the indirect routes including airborne transmission by airborne viral infectivity and transmission by contact with contaminated environmental surfaces ( Harbizadeh et al, 2019 ; Coccia, 2020 ; Kim et al, 2020 ; Noorimotlagh et al, 2020 ; Dargahi et al, 2021 ; Maleki et al, 2021 ). Based on these routes, WHO and other official agencies suggest that people should use face masks, environmental surface disinfectants and alcohol-based hand gel, and do social distancing to prevent viral transmission ( Noorimotlagh, Mirzaee et al 2020 , 2021 ; Maleki et al, 2021 ; Marzoli and Bortolami, 2021 ; Vosoughi et al, 2021 ).…”

The current COVID-19 pandemic that is caused by SARS-CoV-2 has led all the people around the globe to implement preventive measures such as environmental cleaning using alcohol-based materials, and social distancing in order to prevent and minimize viral transmission via fomites. The role of environmental surface contamination in viral transmission in within hospital wards is still debatable, especially considering the spread of new variants of the virus in the world. The present comprehensive study aims to investigate environmental surface contamination in different wards of a hospital as well as the efficacy of two common disinfectants for virus inactivation, and tries to produce an estimate of plastic residue pollution as an environmental side effect of the pandemic. With regard to environmental surface contamination, 76 samples were taken from different wards of the hospital, from which 40 were positive. These samples were taken from contaminated environmental surfaces such as patient bed handles, the nursing station, toilet door handles, cell phones, patient toilet sinks, toilet bowls, and patient's pillows, which are regularly-touched surfaces and can pose a high risk for transmission of the virus. The number of positive samples also reveals that SARS-CoV-2 can survive on inanimate surfaces after disinfection by ethanol 70 % and sodium hypochlorite (0.001 %). The results correspond to the time that the VOC 202012/01 (lineage B.1.1.7) had emerged in the hospital and this should be considered that this variant could possibly have different traits, characteristics, and level of persistence in the environment. The plastic waste as an environmental side effect of the pandemic was also investigated and it was confirmed that the amount of plastic residue for a single (RT) PCR confirmatory test for COVID-19 diagnosis is 821.778 g of plastic residue/test. As a result, it is recommended that for improving plastic waste management programs, considering challenges such as minimizing plastic waste pollution, optimization of gas control technologies in incinerators, process redesign, reduction of single-use plastics and PPE, etc. Is of utmost importance.

The emerging threat posed by COVID-19 pandemic has strongly modified our lifestyle, making urgent to re-consider the humans-environment relationships and stimulating towards more sustainable choices in our daily behavior. Scientific evidences showed that the onset of new viral pathogens with a high epidemic-pandemic potential is often the result of complex interactions between animals, humans and environment. In this context, the interest of the scientific community has also been attracted towards the potential interactions of SARS-CoV-2 with environmental compartments. Many issues, ranging from the epidemiology and persistence of SARS-CoV-2 in water bodies to the potential implications of lockdown measures on environmental quality status are here reviewed, with a special reference to marine ecosystems. Due to current sanitary emergence, the relevance of pilot studies regarding the interactions between SARS-CoV-2 spread and the direct and indirect environmental impacts of the COVID-19 pandemic, that are still a matter of scientific debate, is underlined.

The COVID-19 pandemic had a major impact on life in 2020 and 2021. One method of transmission occurs when the causative virus, SARS-CoV-2, contaminates solids. Understanding and controlling the interaction with solids is thus potentially important for limiting the spread of the disease. We review work that describes the prevalence of the virus on common objects, the longevity of the virus on solids, and surface coatings that are designed to inactivate the virus. Engineered coatings have already succeeded in producing a large reduction in viral infectivity from surfaces. We also review work describing inactivation on facemasks and clothing, and discuss probable mechanisms of inactivation of the virus at surfaces.
