Best Papers from 2021 published in the Environmental Science journals of the Royal Society of Chemistry

As we (PN, ND, KM, PV) acknowledge the best papers published by the Environmental Science family of journals in 2021, we are struck by our good fortune in being able to pursue scientific research and share the best of it with the world. Scientific research focuses on uncovering the truth, but with the inherent limitations of imperfect measurements made by imperfect human researchers. This uncertainty brings a sense of humility to our scientific endeavors, which is enhanced when our research is focused on important topics such as the environment, human health, and the provision of new tools for policy makers. This is a privilege and one that we at Environmental Science: Atmospheres (ESA), Environmental Science: Nano (ESN), Environmental Science: Processes & Impacts (ESPI), and Environmental Science: Water Research & Technology (ESWRT) are helping (albeit slowly) democratize through optional double-anonymised submission, fair and transparent reviews, responsive Editorial Boards, and the publication of research from across the spectrum of focus areas and researcher demographics.

In 2021 we published 39, 283, 153, and 186 papers in ESA, ESN, ESPI and ESWRT respectively that covered areas ranging from the effect of aerosols on climate, to nanoplastics, to indoor air pollutants and their sources. We are excited that next year, publications from our newest Open Access companion journal Environmental Science: Advances (https://www.rsc.org/journals-books-databases/about-journals/environmental-science-advances/) will be included in the Environmental Science best papers round up.

During the first months of 2022, we enlisted our Advisory Boards, Editorial Boards, and Associate Editors to choose the very best papers published in our journals in 2021. Their selection provides examples of the compelling research published in the Environmental Science family of journals and of the research that we are privileged to bring to you each month. From this list, we, the Editors-in-Chief of ESA, ESN, ESPI and ESWRT, selected the overall Best Paper from our portfolio of papers published in 2021.

We are so excited to highlight this top paper, one that highlights the power of a diverse group of researchers, coming from wastewater utilities, consulting firms, and academic and government laboratories, and their pursuit of “the truth” with respect to understanding methodological limitations to facilitate the protection of human health. We are also thrilled to spotlight all the best papers from the Environmental Science family of journals.^1–12 These papers collectively highlight our privilege to advance science, its application, and its diversity.

Overall Best Paper

Pecson, Darby, Haas, Amha, Bartolo, Danielson, Dearborn, Di Giovanni, Ferguson, Fevig, Gaddis, Gray, Lukasik, Mull, Olivas, Olivieri, Qu and SARS-CoV-2 Interlaboratory Consortium, Reproducibility and sensitivity of 36 methods to quantify the SARS-CoV-2 genetic signal in raw wastewater: findings from an interlaboratory methods evaluation in the U.S., Environ. Sci.: Water Res. Technol., 2021, 7, 504–520, https://doi.org/10.1039/D0EW00946F

 

In this Open Access paper, Pecson and colleagues performed a detailed assessment of the methods used to test for SARS-CoV-2, the virus responsible for the global COVID-19 pandemic, genetic material in wastewater. This research determined the variability between methods used at 32 different laboratories across the United States, including commercial, academic, government, and wastewater utility laboratories. The research was carefully performed, and rather than seeking to identify and try to institute a single method for all of the laboratories to utilize, the research instead used split samples to determine how well different methods were able to identify trends in SARS-CoV-2 data over time and determine the prevalence of infection within a given community. The research included the quality control and assurance required to help government officials and public health experts understand how “good” this kind of data was across the country and whether it could be relied upon for identifying, for example, when new surges of infection were beginning in a given community. Perhaps the most useful aspect of the paper is the Discussion, where the limitations of this highly impactful study were identified. Importantly, it was noted that there is not a need for a single complex method to generate useful SARS-CoV-2 data, thus opening the door to larger quantities of data to be obtained and used by governments in understanding the spread of new variants. Nevertheless, the variety of methods used were not able to provide accurate absolute quantification of viral particles, instead pointing to the need to monitor trends at a particular location using a given method, as opposed to trying to quantify numbers of cases and comparing numbers across locations. Finally, the authors provide suggestions for improving data quality moving forward and for future work regarding the selection of the best methods for enhanced sensitivity or use in resource-constrained communities, particularly as this type of wastewater surveillance expands. This paper is impactful and paves the way for future efforts linking rigorous methodological research to the protection of human health.
