“…In certain studies conducted over the past three to four decades, toxic element concentrations in groundwater samples surpassed WHO threshold limits (WHO 2021 ). There have also been reports of toxic elements contamination of groundwater in a number of South Asian countries, including Bangladesh (Simu et al 2018 ; Islam and Islam 2020 ; Zakir et al 2020 ) and China (Li et al 2017 ; Lou et al 2017 ; Lu et al 2018 ), India, and Pakistan (Afzal et al 2014 ; Hassan and Nawaz 2014 ; Usman et al 2017 ). Other countries throughout the world have also seen toxic elements poisoning of groundwater, including Nigeria (Nwankwoala et al 2011 ), Denmark (Jensen et al 2000 ), Egypt (El-Salam and Abu-Zuid 2015 ), Myanmar (Bacquart et al 2015 ), Bolivia (Garcia et al 2005 ), and Russia (Galitskaya et al 2017 ).…”

Providing safe drinking water for the entire world’s population is essential for ensuring sustainable development. The presence of harmful compounds in aquifers, majorly toxic elements, is a serious environmental concern around the globe. This research aimed to quantify for the initial period the amounts of toxic elements in freshwater in the Dehradun Industrial Region of Uttrakhand, India, as well as the associated health risks. The PTEs (potentially toxic elements) Fe, Cd, Mn, Cu, Cr and Pb, Zn, Ni is measured by AAS and compared to BIS and WHO requirements for drinking safety. The order of mean trace element values in all groundwater samples were determined as Fe > Zn > Cu > Ni > Co > Cd > Pb. HPI was discovered to be higher than high class during the research period (HPI > 30), but under the severe contamination criterion of 100. Iron’s MI and PI values were consistently over the threshold limit during the research period, and certain toxic elements were discovered exceptionally near the threshold limit, indicating a severe future influence on groundwater quality. According to PCA (principal component analysis), CM (correlation matrix), and potential health hazard, maximum levels of toxic elements in groundwater in the Dehradun region are attributed to land use patterns, anthropogenic activity, industrial activity, fertilizer and pesticide leaching, and residential waste into the aquifer system. The findings of this study could aid local planners and policymakers in preventing health risks from contaminated aquifers through the deployment of suitable monitoring and mitigation measures.

“…This issue is not limited to Pakistan alone, as several countries in South Asia, including India, China, and Bangladesh, have also reported heavy metal contamination in their groundwater, 32 Pakistan 32d and Bangladesh. 33 These ndings emphasize the urgent need to address and mitigate the contamination of groundwater by heavy metals in order to protect human health. It is essential to implement effective measures to prevent further contamination and ensure the provision of safe drinking water to the population.…”

Environmental exposure to heavy metals, such as lead (Pb) and nickel (Ni), has been implicated in the development of chronic metabolic diseases, including diabetes mellitus (DM). This cross-sectional study aimed to evaluate the detection of PB and Ni in ground water by ICP-OES and in the urine samples of participants by ICP-MS and found the association between Pb and Ni exposure and the risk factors for DM and metabolic disorders in the participants. A total of 2688 participants were recruited from the district of Sargodha in Punjab, Pakistan. Participants were categorized into Pb-exposed and Ni-exposed groups, and further stratified into diabetic and non-diabetic subgroups. In groundwater, Except for pH, the levels of total dissolved solids, electrical conductivity, hardness, and turbidity exceeded the guidelines set by the World Health Organization (WHO) and the concentrations of Ni and Pb in the groundwater samples exceeded the WHO guidelines in the study area. While in the study participants, the concentrations of Pb and Ni were measured in urine samples, and various biomarkers related to DM, lipid profile, inflammation, oxidative stress, liver function, and kidney function were assessed. The results showed significantly higher levels of Pb and Ni in both diabetic and non-diabetic individuals compared to healthy participants. Pb-exposed diabetic participants had higher Pb levels than Pb-exposed non-diabetics, and similarly, Ni-exposed diabetics had higher Ni levels than Ni-exposed non-diabetics. These findings suggest that Pb and Ni exposure may contribute to the development of DM. The study also revealed that Pb and Ni exposure were associated with disruptions in various biomarkers. Pb-exposed diabetics exhibited elevated levels of glycemic index markers, including fasting blood glucose (FBG) and glycated hemoglobin A1c (HbA1c). Ni-exposed diabetics showed elevated levels of inflammatory markers, such as C-reactive protein (CRP) and interleukin-6 (IL-6). Both Pb and Ni exposure were associated with dyslipidemia, as indicated by elevated total cholesterol and LDL levels. Furthermore, Pb and Ni exposure were found to impair liver and kidney function, as evidenced by elevated levels of AST, ALT, creatinine and blood urea nitrogen. Pb exposure was also associated with higher levels of MDA. The study's findings were supported by correlation analyses, which demonstrated significant associations between urinary Pb and Ni concentrations and various biomarkers related to DM and metabolic disorders. In conclusion, this study provides substantial evidence linking Pb and Ni exposure to the development of DM and metabolic disorders in a Pakistani population. The findings highlight the need for stricter regulations and preventive measures to reduce heavy metal contamination in the environment and safeguard public health. Future longitudinal studies and interventions are warranted to further elucidate the mechanisms underlying the association between heavy metal exposure and metabolic diseases.
