Prevalence of antibiotic resistance genes in bacteria from Gomti and Ganga rivers: implications for water quality and public health.

Rivers serve as a significant habitat and water sources for diverse organisms, including humans. An important environmental and public health concern is the increase in antibiotic-resistant bacteria (ARBs) and genes (ARGs) in aquatic ecosystems brought about by excessive pollutant flow. The research highlighted that river water, which is receiving discharge from wastewater treatment plants, is harbouring multidrug-resistant bacteria. River water samples were collected in January, April, July and October 2022 from three separate locations of each Gomti and Ganga river. A total of 114 bacteria were isolated from Gomti as well as the Ganga River. All the isolates were tested for their resistance to various antibiotics by disc diffusion method. The isolated bacteria were tested for the antibiotic resistance genes using PCR and were identified by 16s rRNA sequencing. The ARBs percentages for each antibiotic were as follows: ampicillin (100%); cefotaxime (96.4, 63.1%); erythromycin (52.6, 57.8%); amikacin (68.4, 50.8%); tetracycline (47.3, 54.3%); nalidixic acid (47.3, 45.6%); streptomycin (68.4, 49.1%); gentamycin (43.8, 35%); chloramphenicol (26.3, 33.3%); neomycin (49.1, 29.8%) and ciprofloxacin (24.5, 7.01%). Further, antibiotic resistance genes in Gomti and Ganga water samples disclose distinctive patterns, including resistance to ermB (25, 40%); tetM (25, 33.3%); ampC (44.4, 40%) and cmlA1 (16.6%). Notably cmlA1 resistant genes were absent in all bacterial strains of the Gomti River. Additionally, gyrA gene was not found in both the river water samples. The presence of ARGs in the bacteria from river water shows threat of transferring these genes to native environmental bacteria. To protect the environment and public health, constant research is necessary to fully understand the extent and consequences of antibiotic resistance in these aquatic habitats.

Drainage Basin Analysis of the Sarayan River, Ganga Plain, India

The Sarayan River is a groundwater fed meandering river, originating near Gola Gokaran Nath Town in Lakhimpur Kheri District of Uttar Pradesh in the Ganga Plain. It flows around 170 km before joining the Gomti River at Kaintain hamlet, Sidhauli Tehsil, Sitapur District, Uttar Pradesh. The morphometric analysis of the Sarayan River Basin is explained in the present paper by using Geographical Information System (GIS) technique and Survey of India topographical sheets to integrate basic, shape and derived characteristics. It shows a dendritic drainage pattern, with a surface area of about 2535 km2. The basic parameters identified are, perimeter 383 km, length 112 km and slope 0.80 m/km. The derived parameters such as the relief–ratio (Rr) 0.30 m/km, bifurcation ratio (Rb) 8.82 and RHO coefficient 0.02, describe a gently undulating topography, influencing sediment transport and the formation of extensive alluvial plain. The form factor (Ff) 0.20, circularity index (Rc) 0.22, and elongation ratio (Re) 0.51 indicate the elongated shape of the basin. The Sarayan River Basin is a fourth order river basin with mature topography and dendritic behaviour of the drainage network.

Palaeoclimatic shifts in the Central Ganga Basin during the Middle- to Late Holocene: Exploring the 4.2 ka arid event and its implications in northern India

The Central Ganga Basin is one of the most densely populated regions of India. It is agriculturally diverse and contributes much to the Indian economy. The region has housed numerous ancient and mediaeval empires. This study presents a continuous record of the paleomonsoon from the Chandrika Devi lake, Lucknow district of Uttar Pradesh, India which is linked with paleo vegetational shifts over the last ~6000 years (5871–75 cal yr BP). The chronology of the lake core is based on three accelerated mass spectrometry (AMS) radiocarbon and two Optically Stimulated Luminescence (OSL) dates. The multiproxy data (grain size, major and trace element ratio, total organic carbon (TOC wt%), carbon isotopes (δ13Corg‰) and pollen), suggest that the lake was initially a part of the Gomti river that began to transform into a lake at ~5000 cal yr BP with weakening of the Indian summer monsoon (ISM) in the Central Ganga Basin. The lake formation was completed at ~4100 cal yr BP under the influence of the 4.2 ka arid event. This phase marks the beginning of human presence as well as agricultural activities in the lake region with the appearance of Cerealia pollen and other agricultural taxa. The agricultural activity surrounding the lake catchment peaked at ~3000 cal yr BP. The lake gradually shrank and became a marshy lowland at ~75 cal yr BP. Our study is significant because it is the first comprehensive multiproxy study from the Lucknow region in the Central Ganga Basin on paleomonsoonal variability and its relationship to human activity, agricultural practices during the Late-Holocene with a focus on the 4.2 Ka arid event. Also, pollen record suggests that the changes in agriculture and human activity began just after 4.2 ka arid event in the study area.

Morphometric Analysis and Condition Factor of Freshwater Prawn, Macrobrachium lamarrei (Crustacea-Decapoda) from the Gomti River, Lucknow, Uttar Pradesh, India

The present investigations on morphometric analysis and condition factor of freshwater prawn, Macrobrachium lamarrei (in both sexes) from The Gomti river, Lucknow, Uttar Pradesh, India. The freshwater prawn, locally known as “Jhinga” was the subject of this study. Prawn samples had been collected in different months of both sexes, and a close relation between their length and weight were observed. The morphometric analysis showed that females ranged from 31-57 mm in length, with their weight ranges from 0.31-1.39g, which are larger than the males (21- 36mm) with their higher weight range (0.13- 0.49g). A high correlation coefficient was observed in males (R2 = 0.808) and females (R2 = 0.881) separately. There were significant differences in the condition factors of males and females at P = .05. The lowest condition factor (CF) value for the males was observed in January (CF= 1.06) and highest in September (CF= 1.52), while in the females CF was the highest value in January (CF=0.82) and the lowest one in March (CF=0.75). The sex ratio of male: female (1.0: 2.10) was found, indicating that females are significantly greater in number than males.

During this study, total 16 species of protozoa are observed like Amoeba, Paramecium, Vorticella etc. The identification is made on the basis of the body shape, size, type of locomotion, and structure of macro and micro nucleus. With the help of recent study, we highlighted the taxonomic diversity of freshwater protozoa, including ciliates, flagellates, amoebae and sporozoans in Gomti River, Lucknow.

UNLOCKING THE POTENTIAL: TRANSFORMING THE GOMTI RIVER INTO A MODEL OF RIVER HEALTH

Rampant urbanization and industrialization along the river Gomti banks have led to severe degradation of its water quality and ecological health. The disposal of industrial and domestic sewage directly into the river, encroachment upon its floodplains for urban development, and ineffective waste management practices pose significant threats to its well-being. This paper examines the deteriorating condition of the Gomti River and proposes strategies for revitalizing it into a healthy river ecosystem. Drawing parallels with the Bogota River restoration project, the study identifies key challenges and opportunities for enhancing the health of the Gomti River. It suggests a holistic approach to wastewater management, including the establishment of treatment plants and the implementation of integrated waste management strategies. Additionally, the paper evaluates the impact of riverfront development projects on the rivers ecological integrity and underscores the need for sustainable urban planning practices to mitigate further degradation. By analyzing case studies and best practices from around the world, the paper provides insights into effective river restoration strategies and emphasizes the importance of community engagement and stakeholder collaboration in achieving long-term sustainability goals for the Gomti River

Assessment of the Surface Water Quality of the Gomti River, India, Using Multivariate Statistical Methods

In the present study, the quality of the surface water of the Gomti river (Lucknow, India) was investigated. Lucknow is situated in the centre of Uttar Pradesh, which is most the populated state in India. The locality has experienced rapid, unregulated development activities and population growth in recent decades, both of which have had a negative impact on its ecosystem and environment. Continuous monitoring is required to maintain the ecosystem at the desired level. Nine samples of river water were collected from the Gomti River in Lucknow, and they were analysed for a total of nine different characteristics, including pH, turbidity (Tur), dissolved oxygen (DO), total dissolved solids (TDSs), chemical oxygen demand (COD), chloride ion (Cl-) concentration, temperature (T), biochemical oxygen demand (BOD5) and total hardness (TH). The observed data were analysed using multivariate statistical methods. A cluster analysis (CA) was used to sort the sampling locations into different groups, and a principal component analysis (PCA) was used to find the different sources of pollution. Using a cluster analysis, all the water quality parameters were divided into three groups. Cluster 1 represented the less polluted sites, cluster 2 represented the moderately polluted sites and cluster 3 represented the highly polluted sites. Sampling sites SS8, SS4, S99 and SS7 were highly polluted because of nearby pollution sources such as domestic wastewater and runoff storm water. The principal component analysis yielded two meaningful components that explained 82.4% of the total variation in the data. The first factor and second factor explained 59.022 and 23.363 percentages of the total variance, respectively. It was noticed that major sources of pollution for the Gomti river are storm water runoff and the release of domestic and industrial wastewater from residents and industries, respectively. This study will help policy makers to ensure sustainable practices and reduce negative impacts on the availability and quality of water, allowing for the most efficient use of the Gomti River.

Seasonal Variations of pH and Dissolved Oxygen Concentrations in Major Rivers of Uttar Pradesh

The variations in pH and Dissolve Oxygen (DO) concentrations were analysed in surface river water samples for three seasons Pre-Monsoon, Monsoon and Autumn (January to December 2022) for four major rivers Ganga, Yamuna, Gomti and Hindon flowing through Uttar Pradesh, India. For river Ganga pH range varied from 7.65 to 8.47 and DO varied from 6.4mg/l to 9.26mg/l. For river Yamuna pH range varied from 7.31 to 10.5 and DO varied from 0 to 8.1mg/l. Gomti river showed, pH range between 7.2 to 8.48, while DO varied from 0.63mg/l to 8.4mg/l. For, river Hindon, pH varied from 6.8 to 7.66 and DO observed was between 0 to 1.8mg/l. Correlation Matrix showed a significant weak positive correlation between pH and DO for all three seasons for rivers Ganga and Yamuna, while river Gomti showed a significant weak positive correlation in Pre-Monsoon and Monsoon season, and a weak negative correlation in Autumn lastly river Hindon showed weak negative correlation between pH and DO for Pre-Monsoon, and Monsoon and a weak positive significant correlation for Autumn season. Dissolved Oxygen was found in good concentration in river Ganga, and almost nilfor river Hindon. An increasing trend line for DO was observed for rivers Ganga and Yamuna while river Gomti showed a constant trend line lastly river Hindon showed almost nil DO. This study helped to identify the variations of pH and DO, and also to find the correlation between them for Pre-Monsoon, Monsoon and Autumn seasons for the river water samples. The study will prove helpful for designing of water treatment plants accompanying seasonal variations.

Assessment of environmental and human health risk from pesticide residues in river Gomti, Northern India.

Rivers get polluted with diverse types of hazardous and toxic substances, pesticides being one of them. The water and sediment of rivers get contaminated with pesticide residues coming through the run-off of vast agricultural fields along the catchment area and also from domestic sewage water. The residues get bio-concentrated and bio-accumulated in different aquatic organisms and animals including fishes along the food chain. Fish, one of the important and chief sources of proteins, are consumed by humans. The presence of toxic substances like pesticides in any food item is undesirable for the fear of health hazards. We have monitored the status of pesticide residue in river Gomti, a tributary of River Ganga that passes through the Uttar Pradesh state of India. Water, sediment, and fish samples collected from the different locations along the river stretch were analyzed for 34 targeted pesticide compounds belonging to organochlorines (OC), organophosphates (OP), and synthetic pyrethroids (SP) groups. In 52% of water, 30% of sediment, and 43% of fish samples residues of OCs were detected while the OPs were present in 33%, 25%, and 39% of samples respectively. However, none of the SPs could be recorded in any sample. The concentrations of the pesticides in water indicate stress conditions to some extent to aquatic life, but based on the human health risk assessment it can be concluded that consumption of fishes from the river contaminated with different OC or OP residues would not pose any direct risk to the consumers.
