“…Furthermore, it poses a significant health concern in Bangladesh and surrounding regions as well (Khatun et al, 2020) Inorganic arsenic (As) is found in drinking water in most developing countries including Bangladesh. It is harmful to human health (Ahmad et al, 2023;Noh CH et al, 2023). Serious health issues like cancer, hyperkeratosis, lung, and heart disease can be brought on by it (Khan et al, 2022;Sinha et al, 2020).…”

Arsenic (As) is found in contaminated groundwater as the source of pollution. In this study, 60 Long-Evans rats were used to assess the levels of As in the blood and organs and to compare the effectiveness of vitamin A and spirulina (Spirulina platensis) in preventing a chronic As accumulation. Twelve rats were assigned to each group of animals. The experimental groups were the control (T0), As (T1), As + spirulina (T2), As + vitamin A (T3), and As + spirulina + vitamin A (T4). The T1, T2, T3, and T4 groups were orally administered with sodium arsenite (NaAsO2) @ 4 mg/kg body weight (BW) for 63 days. In addition to NaAsO2, the T2 and T4 received 1 g/kg BW spirulina. The T3 and T4 received 2500 IU/kg BW vitamin A for 63 days, respectively. Four rats were euthanized in each group to evaluate the As concentration in the liver, lung, kidney, and blood at an interval of 21 days. Total As concentration was quantified from the organs using Hydride Generation Atomic Absorption Spectrophotometer (HG-AAS). The results revealed that the T0 had no visible clinical symptoms. However, after 63 days of treatment, the T1 (As only administration) accumulated more As compared to other groups. The concentration of As was highest in the blood, then in the kidney, liver, and lung. In this case, spirulina and vitamin A substantially (p<0.01) decreased the concentration of As in the rats' organs and tissues Spirulina is more effective than vitamin A in reducing As accumulation in rats. In summary, the combination of both spirulina and vitamin A has a positive impact on reducing the accumulation of chronic arsenicosis in rats compared to the individual administration of either spirulina or vitamin A alone.

“…4 The excessive extraction of groundwater for irrigation purposes further exacerbates the problem, altering the flow patterns and concentration of arsenic in the aquifers. 5 The health implications of arsenic toxicity in Southern Punjab are alarming. Prolonged exposure to arsenic-contaminated water has been linked to various health conditions, including skin lesions, cardiovascular diseases, respiratory problems, and an increased risk of cancer.…”

Background: Arsenic contamination in groundwater is a global public health concern, and Southern Punjab, Pakistan, is one of the regions severely affected by this crisis. Arsenic toxicity in drinking water poses significant risks to human health, including increased incidences of various diseases. It is crucial to assess the extent of arsenic toxicity in Southern Punjab and develop sustainable treatment solutions to mitigate its impact on the population. Objective: This research article aims to assess the level of arsenic toxicity in Southern Punjab, Pakistan, and propose sustainable treatment solutions for mitigating its impact. The specific objectives include evaluating the sources and pathways of arsenic contamination, determining the extent of exposure in the region, assessing the health implications, and developing effective and sustainable treatment strategies tailored to the local context. Method: The research employed a multidisciplinary approach that integrated environmental analysis, epidemiological studies, and community engagement. Groundwater samples were collected from various locations in Southern Punjab, and the arsenic levels were determined using established analytical techniques. Epidemiological studies were conducted to assess the health impacts of arsenic toxicity on the local population. Socioeconomic surveys were also conducted to identify vulnerable communities and understand the cultural and socioeconomic factors influencing exposure and mitigation. Result: The analysis of groundwater samples revealed elevated levels of arsenic in Southern Punjab, indicating significant contamination. The epidemiological studies identified a higher incidence of arsenic-related health conditions in the affected population, including skin lesions, respiratory problems, and various cancers. The socioeconomic surveys highlighted the vulnerable communities and their specific needs in terms of arsenic mitigation. Based on these findings, sustainable treatment solutions were developed, taking into account the local context, available resources, and community involvement. Conclusion: The findings of this research underscore the urgent need to address the arsenic toxicity crisis in Southern Punjab, Pakistan. The high levels of arsenic contamination in groundwater pose severe health risks to the population. The study highlights the importance of developing sustainable treatment solutions tailored to the local context. Implementing these solutions will require a collaborative effort involving policymakers, researchers, healthcare professionals, and community members. By mitigating the impact of arsenic toxicity, the overall well-being and quality of life of the population in Southern Punjab can be significantly improved.

“…Arsenic poisoning in Bangladesh, however, has cast a pall over them all, with over 75 million people at risk and countless having reached the point of no return (Faroque and South 2022). Of 5 million shallow tube wells in Bangladesh, arsenic contamination has polluted 3 million of them (Ahmad and Khan 2023; Sha uddin and Karim 2003). Several studies have also discovered that excessive groundwater extraction causes water level variations and that aeration of the soil causes pyrite decomposition, which leads to arsenic leaching.…”

Underground water is one of the world's most important sources of fresh drinking water. However, various contaminants mix with groundwater, such as arsenic. This study aimed to ascertain the present condition of arsenic concentration, its spatial pattern, and its relationship with depth and to assess the associated health risks in the Gangni Union in Alamdanga Thana of Chuadanga district. Systematic sampling was used to gather water samples (í µí± = 100) along with depth information from these tube wells. Water samples were analyzed with the Hach EZ, Dual-Range Arsenic Test Kit (Range: 0.00-0.5 mg/L). This study used both geostatistical (spatial autocorrelation, Hotspot analysis, and IDW) and statistical (descriptive and correlation statistics) methods. The arsenic content of the samples tested ranged from 0.0004 (mg/l) to 0.10 (mg/L). Arsenic levels in almost 42% of the samples were above the WHO standard, 21% were above the Bangladesh standard, and 37% were below both standards. With the same standard, the spatial distribution shows that 63% of the total area is arsenic contaminated. Hotspot’s analysis reveals that the central and southern northern parts of the study area are more arsenic-contaminated than the other parts. Children have a higher average daily dose (ADD) range (8.33E-06-0.00181) than adults (2.78E-06-0.0006). Similarly, the hazard quotient (HQ) value is also higher for children (0.0277-6.033) than for adults (0.0092-2.011). Finally, the Pearson correlation coefficient, r (98) =-.7580, p = 0.000, proved that there is a negative linear relationship between concentration values and depth, meaning that increasing depth will reduce arsenic contamination from tube well water.
