Chemicals in wastewater may help track COVID-19


The last issue of Wiley’s Research Headlines highlighted part one of a study in Environmental Toxicology and Chemistry that involved analysis of sludge from a wastewater treatment plant in Connecticut, and revealed trends in levels of chemicals such as pharmaceuticals and drugs during the first wave of the COVID-19 pandemic. In part two of the study, investigators evaluated the relationships among detected chemical features and parallel measurements of COVID-19 metrics, including levels of SARS-CoV-2 RNA in the sludge, COVID-19 case numbers, and hospital admissions.

The investigators found multiple chemical features that relate strongly to COVID-19 metrics and have not previously been studied in relation to wastewater and COVID-19.
