Antimicrobial resistance (AMR) is a growing global health threat. This study investigated antibiotic in E. coli isolates from municipal wastewater (86 isolates) and clinical urinary tract infection (UTI) cases (34 Grenadian community, using data January 2022 to October 2023. Antibiogram data, assessed per WHO guidelines for Critically Important antimicrobials (CIA), showed the highest levels both samples ampicillin, followed by amoxicillin/clavulanic acid nalidixic acid, all classified as...
Wastewater-based epidemiology (WBE) is a valuable tool for monitoring pathogen spread in communities; however, current protocols mainly target non-enveloped viruses. This study addresses the need standardized methods to detect both enveloped and viruses by testing four aluminum hydroxide adsorption–precipitation techniques. Wastewater samples were spiked with an virus surrogate (Φ6 bacteriophage) (MS2 coliphage), viral recovery was assessed using reverse-transcription quantitative PCR...
Lead (Pb) contamination was evaluated in 24 contaminated soils and sediments samples, representative of areas affected by mining, agricultural, commercial residential activity, during the rainy dry season. Pseudo-total concentration (15.7–527.2 mg kg−1) (16.3–4273.3 determined protocols were developed to analyze its chemical form, potential mobility bioavailability. Five geochemical phases (exchangeable fraction, carbonate Fe/Mn oxide organic fraction residual fraction) obtained for...
Most Caribbean islands do not have air pollution surveillance programs. Those who live in these countries are exposed to ambient from a variety of sources including motor vehicles, ocean-going vessels, and Saharan dust. We conducted an sampling exposure study Grenada describe daily changes fine particulate matter (PM2.5) pollution, during dust episodes. Further, we assessed the impacts COVID-19 public health interventions on PM2.5 concentrations 2020. Four fixed-site PurpleAir monitors were...
