Sediment serves as a heavy metal store in the riverine system and provides information about the river’s health. To understand the distribution of heavy metal content in the Ganga River basin, a total of 25-bed sediment and suspended particulate matter (SPM) samples were collected from 25 locations in December 2019. Bed sediment samples were analyzed for different physio-chemical parameters, along with heavy metals. Due to insufficient quantity of SPM, the samples were not analyzed for any physio-chemical parameter. The metal concentrations in bed sediments were found to be as follows: Co (6–20 mg/kg), Cr (34–108 mg/kg), Ni (6–46 mg/kg), Cu (14–210 mg/kg), and Zn (30–264 mg/kg) and in SPM, the concentrations were Co (BDL-50 mg/kg), Cr (10–168 mg/kg), Ni (BDL-88 mg/kg), Cu (26–80 mg/kg), and Zn (44-1186 mg/kg). In bed sediment, a strong correlation of 0.86 and 0.93 was found between Ni and Cr, and Cu and Zn respectively and no significant correlation exists between organic carbon and metals except Co. In SPM, a low to moderate correlation was found between all the metals except Zn. The risk indices show adverse effects at Pragayraj, Fulhar, and Banshberia. Two major clusters were formed in HCA among the sample points in SPM and bed sediment. This study concludes that the Ganga River at Prayagraj, Bansberia, and Fulhar River is predominately polluted with Cu and Zn, possibly posing an ecological risk. These results can help policymakers in implementing measures to control metal pollution in the Ganga River and its tributaries.

“…It is advised to incorporate a range of indicators (health, income, and education, for example) chosen according to their functional links and systemic influence in order to increase the reliability of the assessed results [108]. Indicators that show functional links, such as governance and the rate of capacity creation, significantly influence the definition of a system's adaptive capability [109]. Therefore, it is likely that judgements will be less than ideal if any of these pertinent signs are ignored.…”

The Earth’s water resources, totalling 1.386 billion cubic kilometres, predominantly consist of saltwater in oceans. Groundwater plays a pivotal role, with 99% of usable freshwater supporting 1.5–3 billion people as a drinking water source and 60–70% for irrigation. Climate change, with temperature increases and altered precipitation patterns, directly impacts groundwater systems, affecting recharge, discharge, and temperature. Hydrological models are crucial for assessing climate change effects on groundwater, aiding in management decisions. Advanced hydrological models, incorporating data assimilation and improved process representation, contribute to understanding complex systems. Recent studies employ numerical models to assess climate change impacts on groundwater recharge that could help in the management of groundwater. Groundwater vulnerability assessments vary with the spatial and temporal considerations, as well as assumptions in modelling groundwater susceptibility. This review assesses the vulnerability of groundwater to climate change and stresses the importance of accurate assessments for sustainable water resource management. It highlights challenges in assumptions related to soil and aquifer properties, multiple stressors, adaptive capacity, topography and groundwater contamination processes, gradual sea level rise scenarios, and realistic representations of the region of study. With the advancements in hydrological modelling, including the integration of uncertainty quantification and remote sensing data, artificial intelligence could assist in the efforts to improve models for assessing the impacts of climate change on hydrological modelling.

“…where multimetal levels are high due to increased temperature and less flushing of aquifers (e.g., in Bangladesh) are some of the factors responsible for metal toxicity [7] A large part of the cultivated land is flooded with water which is contaminated with heavy metals via increased reducing environment in the aquifers, enhancing anion exchange and mixture of waters from deep and shallow aquifers. In Bangladesh, arsenic is released from solids by reduction.…”

Extensive use of heavy metals has posed a serious concern for ecosystem and human too. Heavy metals are toxic in nature and their accumulation in human body causes serious disorders such as neurological disease, cardiac disease, gastrointestinal problems, skin disorders, reproductive disease, lungs diseases, and so on. Furthermore, heavy metals not only affect the human health but also have a negative impact on the economy. In the current review, we have elaborated the impact of heavy metal exposure on human health and socioeconomics. We have discussed the molecular mechanism involved in the heavy metal‐induced human disorders such as oxidative stress, neuroinflammation, and protein misfolding. Finally, we discussed the preventive measure and treatment strategy that could counter the negative effects of heavy metal intoxications. In conclusion, there is a substantial correlation between heavy metals and the onset and advancement of several health issues. Chelation treatment could be a useful tactic to lessen the toxic metal load and the difficulties that come with it.
