Summary: Developed countries have actively shared wastewater surveillance information during the COVID-19 pandemic, while low- and middle-income countries have shown limited activities in this area. This study highlights the relevance of a multiparty effort and demonstrates the usefulness of wastewater surveillance in viral monitoring, particularly in identifying hotspot areas and tracking asymptomatic individuals. It emphasizes the need for improved collaboration and utilization of wastewater-based epidemiology methodology.

Summary: Wastewater-based epidemiology (WBE) has significantly developed during the COVID-19 pandemic, with widespread global application in monitoring the spread of the SARS-CoV-2 virus in urban communities. This mini-review examines the impact of the pandemic on WBE, based on the analysis of 1305 scientific reports. The findings demonstrate the migration of WBE's focus to studying the coronavirus and changes in research funding sources, collaborators, and study subjects.

Summary: Wastewater-based epidemiology (WBE) is a useful method for monitoring SARS-CoV-2, providing valuable genomic information on viral variants. This study evaluated the impact of sequencing throughput on genome coverage, mutation detection, and variant deconvolution using mock wastewater samples. The results showed that sequencing throughput greater than 0.5 Gb produced reliable genomic analysis results. Wastewater genomic sequencing was able to detect variant trends earlier than clinical data, and it demonstrated the potential for identifying novel mutations and unique alleles.

Summary: The COVID-19 pandemic has highlighted the potential of virus transmission through fecal-oral route and the presence of virus in sewage and wastewater poses a potential threat. Asymptomatic patients could also play a role in disease transmission. Therefore, wastewater-based surveillance could offer valuable insights into virus prevalence and serve as an early warning system.

Summary: This study in Padua, Italy, detected the presence of SARS-CoV-2 RNA in treated and untreated wastewaters, with the virus showing persistence after 24 hours at 4°C. Hospitalization data suggested that wastewater-based epidemiology detection can identify approximately 1 COVID-19 case per 531 inhabitants. These findings strongly support the potential role of wastewater-based epidemiology in COVID-19 environmental surveillance.

Summary: The quantification of viral genomes in wastewater reflects the prevalence of viral infections within the community. The study found that the spread of common enteric viruses in the community was affected by the Swedish COVID-19 interventions. The winter seasonality of norovirus GII and rotavirus in wastewater was interrupted shortly after the introduction of the COVID-19 interventions, and they remained at low levels throughout the pandemic.

Summary: Transmission of the novel coronavirus (SARS-CoV-2) in humans can occur through respiratory droplets or contact with contaminated surfaces. The presence of the virus in feces and sewage systems raises public health concern, with monitoring through sewage potentially providing epidemiological data on COVID-19 trends. Tracking the virus in sewage could serve as an early warning system for public health authorities to take necessary actions.

Summary: The discharge of dye-contaminated effluents in aquatic environments has serious negative effects on aquatic ecosystems and human health. Layered double hydroxides (LDHs) and their derivatives have gained significant attention as a technology for treating dye-contaminated water due to their variable shapes, stability, high surface area, uniform positive charge distribution on the surface, interplanar spacing, simplicity of synthesis, and adaptability for creating different types of composites. This review provides an overview of the use of LDHs and their derivatives for treating dye-contaminated water, including their photocatalytic applications, efficiency, degradation mechanisms, and factors affecting the photodegradation efficiency. The stability, regeneration, and reusability of LDH- and their derivative-based photocatalysts are also discussed.

Summary: Two environmentally friendly materials (LGP and GBP) were successfully synthesized from local resources in Cameroon and their potential for removing Ni(II) and Co(II) from aqueous solutions was investigated. LGP had a higher specific surface area than GBP, but GBP exhibited stronger adsorption capacity, possibly due to the presence of negatively charged groups in its structure. LGP fitted well with Langmuir and Dubinin-Radushkevic models, while GBP was best described by the Freundlich model.

Summary: Two-dimensional MoS2 has great potential as a photocatalytic material for water treatment, but its pristine nanostructure has limitations due to high recombination rate. This review summarizes the strategies used to improve the photocatalytic performance of MoS2, including scaling down to few/mono nanosheets, constructing heterojunctions with other materials, and defect engineering. The review also discusses the misinterpretation of charge transfer in heterojunctions and the generation of reactive species. Furthermore, recent progress in MoS2-based photocatalytic systems for environmental remediation is discussed, along with future research directions for designing superior photocatalysts.

Summary: Activated carbon derived from peat-based biomass was sulfurized and magnetized to form magnetically-engineered sulfurized peat-based activated carbon (MEPBAC), which was used for the adsorption of caffeine (CFN) and sulfamethoxazole (SMX) from aqueous media. The modification increased the surface area and introduced sulfur-groups and Fe-based nano-structures in MEPBAC. The sulfur-groups enhanced adsorption efficiency, while the Fe-based nano-structures facilitated easy magnetic separation, resulting in high reusability with consistent removal efficiency.
