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...
ABSTRACT we made the first ever successful effort from India to detect genetic material of SARS-CoV-2 viruses understand capability and application WBE surveillance in India. Sampling was carried out on 8 27 May, 2020 Old Pirana Waste Water Treatment Plant (WWTP) at Ahmedabad, Gujarat with 106 million liters per day (MLD) capacity receiving effluent Civil Hospital treating COVID-19 patient. All three i.e. ORF1ab, N S genes were discerned influents no gene spotted collected May 2020. Temporal...
We report the working of a smartphone-based optical sensor for measurement pH level colorless aqueous media. By integrating readily available laboratory components to camera smartphone, we convert smartphone into visible spectrophotometer with spectral resolution 0.345 nm/pixel. Evanescent light signal from designed sensing setup is allowed interact sensitive dye sample. The transmitted region then captured by in form modulated image spectrum. can detect change medium 0.12 unit within range...
Abstract We evaluated the anthropogenic forcing and exceedance probability of arsenic vulnerability in Quaternary Alluviums Mid-Gangetic Plain through coupled application hydrogeochemical analyses, inverse modelling, kriging, bivariate multivariate statistical analysis (MVA). Fifty-seven groundwater samples (total 171) each were collected during pre-monsoon (April 2015), monsoon (July 2015) post-monsoon (January 2016). Seasonal cyclicity ion exchange reverse was observed, with former being...
Wastewater-based epidemiology (WBE) is a promising approach to understand the actual prevalence of COVID-19 disease at community level. Different studies have cited presence SARS-CoV-2 in wastewater samples. In present study, eighteen influent samples from different sewage treatment plants and pumping stations (5 Vadodara city, 4 Gandhinagar, 9 Ahmedabad city) were collected analyzed for RNA Gujarat state, India. The results showed highest effective gene concentration (3078 copies/L),...
