Thus, in order to overcome these barriers with conventional techniques, biosensors were produced, which are being utilized in multiple sectors of monitoring the environment.

This study focuses on evaluating the water quality parameters of Delhi’s five urban wetlands including Hauz Khas Lake (HZL), Sanjay Lake (SL), Bhalswa Lake (BL), Vasant Kunj Lake (VKL), and Sanjay Van Lake (SVL) during winter (14—17^th January 2023) and summer (13—15^th May 2023) seasons. A total of 200 samples (20 samples from each lake) from HZL, SL, BL, VKL, and SVL were collected and analysed for 24 physicochemical parameters in both the seasons. Multivariate analysis was performed using a correlation matrix and principal component analysis (PCA)–biplot. Hydrochemical analysis was performed using Piper trilinear and Gibbs diagrams. Water suitability for irrigation was accessed using the chlorinity index, sodium adsorption ratio (SAR), Wilcox diagram, and Kelly index/ratio. Suitability for industrial purposes was evaluated using the Langelier saturation index (LSI) and Ryznar stability index (RSI). Drinking water suitability was assessed through the water quality index (WQI). The average (n = 3) water quality parameter values were compared to BIS and WHO drinking water standards. The average pH for HZL, SL, BL, VKL and SVL was alkaline (ranging from 7.2 to 9.9) in both the seasons. In winter, 4 parameters exceeded BIS permissible limits in HZL, 9 in SL, 12 in BL, 7 in VKL, and 6 in SVL. A similar trend was observed in summer, indicating that SVL and HZL are less polluted than SL, BL, and VKL. The chlorinity index, SAR, Kelly ratio, and Wilcox diagram indicated BL water’s unsuitability for irrigation in both seasons. RSI values above 8 for HZL, SL, BL, VKL, and SVL suggest corrosive nature of the water samples collected in both seasons.

Therefore, the main objective of this study was to develop adsorbents with brown flaxseed and orange peel waste impregnated with copper and silver nanoparticles using green synthesis to evaluate the antibacterial activity of these adsorbents against two bacterial strains, <em>Escherichia coli</em> and <em>Pseudomonas aeruginosa</em>, in contaminated water. For the synthesis of the nanomaterials, copper and silver nitrates were used as precursors, and <em>Moringa oleifera</em> leaf extract as a reducing agent. For the microbiological tests, MIC and MBC were initially evaluated. Subsequently, adsorption, bacterial growth curve, and time-kill tests were carried out for <em>E. coli</em> and <em>P. aeruginosa</em>. The antibacterial and bactericidal activities of the functionalized materials were demonstrated. The proposed adsorption mechanism reported that increasing the mass favored a higher percentage of bacterial reduction. However, the adsorbents functionalized with copper oxide nanoparticles showed better results against the bacteria under study, using the lowest mass of material (0.05 g), achieving a 99 % reduction of bacterial biomass after 24 h of treatment.
