“…Furthermore, several volatile terpene compounds emitted by trees induce anti-inflammatory responses, thus reducing respiratory system inflammation. This may be of particular interest for the coronavirus 2019 pandemic (COVID-19)(Dai et al 2021 ; Ufnalska and Lichtfouse 2021 ; He et al 2021 ; Khan et al 2021 ) caused by SARS-CoV-2, as discussed in the literature (Roviello et al 2021 ; Roviello and Roviello 2021a , b ). Concerning riverside forest bathing, the main volatile organic compound emitted from riparian vegetation, i.e.…”

“…Environmental pollution and climate change are presenting as two of the most globally critical issues in the context of the coronavirus pandemic (COVID-19) and circular economy (Muhammad et al 2020 ; Ufnalska and Lichtfouse 2021 ). The advent of nanoscience and nanotechnology can solve these problems; thereby, holding the key to economic recovery, and environmental mitigation (Weiss et al 2020 ; Tang et al 2021 ).…”

Green synthesis of ZrO2 nanoparticles and nanocomposites for biomedical and environmental applications: a review

Pollution and diseases such as the coronavirus pandemic (COVID-19) are major issues that may be solved partly by nanotechnology. Here we review the synthesis of ZrO 2 nanoparticles and their nanocomposites using compounds from bacteria, fungi, microalgae, and plants. For instance, bacteria, microalgae, and fungi secret bioactive metabolites such as fucoidans, digestive enzymes, and proteins, while plant tissues are rich in reducing sugars, polyphenols, flavonoids, saponins, and amino acids. These compounds allow reducing, capping, chelating, and stabilizing during the transformation of Zr 4+ into ZrO 2 nanoparticles. Green ZrO 2 nanoparticles display unique properties such as a nanoscale size of 5–50 nm, diverse morphologies, e.g. nanospheres, nanorods and nanochains, and wide bandgap energy of 3.7–5.5 eV. Their high stability and biocompatibility are suitable biomedical and environmental applications, such as pathogen and cancer inactivation, and pollutant removal. Emerging applications of green ZrO 2 -based nanocomposites include water treatment, catalytic reduction, nanoelectronic devices, and anti-biofilms.

“…Protocols and guidelines should be used in healthcare facilities to ensure the best conditions for the patients and healthcare workers. However, individuals should not have the illusion that only hygiene measures can prevent the viral spread and visit overcrowded places, putting their health at significant risk (Australia 2020 ; Carraturo et al 2020 ; Casanova et al 2010 ; Chan et al 2006 ; Eslami and Jalili 2020 ; Kampf et al 2020 ; Medicine 2006 ; Otter et al 2016 ; Sylwia Ufnalska and Eric Lichtfouse 2021a , b ; Yang 2020 ).…”

“…The survival capacity of the virus on personal protective equipment depends on the material. The reuse of personal protective equipment is only recommended when adequate supplies cannot be obtained (Australia 2020 ; Carraturo et al 2020 ; Casanova et al 2010 ; Chan et al 2006 ; Eslami and Jalili 2020 ; Kampf et al 2020 ; Medicine 2006 ; Otter et al 2016 ; Sylwia Ufnalska and Eric Lichtfouse 2021a , b ; Yang 2020 ).…”

“…Although many strategies have been applied to combat the spread of the virus, care should be given to the tending that we adapted from the beginning of the pandemic, to focus only on short-term methods to prevent further transmission and at the same time ignore the future results. For instance, possible allergies and skin irritation that may be caused by the daily use of disinfectants and masks should not be neglected (Australia 2020 ; Carraturo et al 2020 ; Casanova et al 2010 ; Chan et al 2006 ; Eslami and Jalili 2020 ; Kampf et al 2020 ; Medicine 2006 ; Otter et al 2016 ; Sylwia Ufnalska and Eric Lichtfouse 2021a , b ; Yang 2020 ).…”

The coronavirus 2019 pandemic, induced by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has strongly altered healthcare systems and the economy worldwide. The lack of knowledge on this virus has led to the implementation of uncertain strategies and measures to fight the pandemic. Here, we review environmental factors that control viral transmission, such as air, temperature, humidity, food, water and sewage, insects, inanimate surfaces, hand hygiene, and social distancing. The main route of viral transmission is the respiratory tract through aerosols. Masks and social distancing are effective in ceasing air transmission. Proper cleaning of surfaces and hand disinfection are required, especially in healthcare units. Food should be handled properly, and food handlers should work based on hygienic protocols. Water and sewage transmission, and transmission through insects appear less important than other environmental factors.
