“…If this virus is not eradicated, we should think on further screening focusing on wastewater (Martínez-Puchol et al, 2020 -have recently published a paper dealing with related aspects), but also on sewage sludge (as shown by Nag et al, 2020 -evaluating survival of bacteria and viruses causing different diseases, as well as in previous papers, such as that by Zhao and Liu, 2019), soils and sediments (Katz et al, 2018;Nag et al, 2020;Zhao and Liu, 2019), crops (Ahmed et al, 2019;Nag et al, 2020;Zhao and Liu, 2019), animals (Pruvot et al, 2019), surface and ground-waters (Corsi et al, 2014;Givens et al, 2016). Further research should also focus on eventual technical treatments, including biosorbents and other materials to retain and/or inactive this and other pathogens circulating in these environmental compartments, before and after going out from wastewater treatment plants (in case of these treatment systems existing, as it could be worse, with spreading of untreated wastes).…”
