By Bhavana KunkalikarJan 24 2023Reviewed by Danielle Ellis, B.Sc. In a recent study published in PLOS Global Public Health, researchers performed severe acute respiratory syndrome coronavirus 2 surveillance in UK airports using wastewater monitoring.
About the study In the present study, the team explored sewage found in terminal and aircraft samples at three international airports in the United Kingdom for one to three weeks. Results The BE-NaNO3/PEG precipitation approach demonstrated the highest virus recovery among the studied procedures, for the SARS-CoV-2 N1 gene fragment as well as the phi6 process control virus. Also, a Shapiro-Wilk normality test revealed that the data distribution for phi6, SARS-CoV-2, and crAssphage deviated remarkably from normality.
All samples collected at Edinburgh Airport reported high amounts of crAssphage. However, pumping station , JR2, and JR3 sites exhibited much greater turbidity, ammonium levels, and electrical conductivity than WWTP and JR1 sites. No remarkable trends were noted in SARS-CoV-2 concentrations over time at any of the sites sampled.
