In this study, we report the implementation of a comprehensive wastewater surveillance testing program at university campus in Singapore to identify Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infected individuals and usage pharmaceuticals personal care products (PPCPs) as well other emerging contaminants (ECs). This unique co-monitoring simultaneously measured SARS-CoV-2 with chemical markers/contaminants COVID-19 situation evolved from pandemic endemic stages, following...
Increased concern has recently emerged pertaining to the occurrence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in aquatic environment during current disease 2019 (COVID-19) pandemic. While infectious SARS-CoV-2 yet be identified environment, virus potentially enters wastewater stream from patient excretions and a precautionary approach dictates evaluating transmission pathways ensure public health safety. Although enveloped viruses have presumed low persistence water are...
β-Lactam antibiotics such as penicillins and cephalosporins are extensively used for human infection therapy. Consistent unintended exposure to these via food water is known promote antibiotic-resistant bacterial pathogenesis with high morbidity mortality in humans. An optical enzymatic biosensor rapid point-of-use detection of has been developed tested. Enzymatic hydrolysis β-lactams, on the electroactive polyaniline nanofibers, altered polymeric backbone from emeraldine base form salt,...
Quaternary ammonium compounds (QACs) are commonly used in many products, such as disinfectants, detergents and personal care products. However, their widespread use has led to ubiquitous presence the environment, posing a potential risk human environmental health. Several methods, including direct indirect photodegradation, have been explored remove QACs benzylalkyldimethyl (BACs) alkyltrimethyl (ATMACs) from environment. Hence, this research, systematic review of literature was conducted...
Predicting the hotspots of antimicrobial resistance (AMR) in aquatics is crucial for managing associated risks. We developed an integrated modeling framework toward predicting spatiotemporal abundance antibiotics, indicator bacteria, and their corresponding antibiotic-resistant bacteria (ARB), as well assessing potential AMR risks to aquatic ecosystem a tropical reservoir. Our focus was on two sulfamethoxazole (SMX) trimethoprim (TMP), Escherichia coli (E. coli) its variant resistant...
Abstract A suitcase laboratory was used for 16S rRNA amplicon sequencing to assess microbial water quality in the holy Bagmati River, Kathmandu, Nepal. SourceTracker analysis and Volcano plots revealed that communities downstream part of river were mainly contributed by untreated sewage. Seasonal variability sewage microbiome reflected quality. The bacterial genera Acidovorax, Geobacillus Caulobacter predominated upstream sites, while containing putative human pathogens gut bacteria, such as...
