“…4 Long time exposure to arsenic results in its accumulation in muscles, nails, hair, and skin which leads to different complications and disorders. 5,6 The complications of arsenic poisoning about the heart will cause prolonged and severe abnormal cardiac repolarization, resulting in a fatal arrhythmia. 7 It will also cause coronary heart disease and peripheral vascular disease in humans.…”

Introduction: Arsenic toxicity has posed troublesome health concerns in the world and many of the toxic effects of arsenic are related to its effect on oxidative stress. The aim of the present study is to evaluate histopathological and antioxidant enzymes changes in oxidative stress status induced by sodium arsenite in rats. Materials and Methods: All experiments were carried out in male Wistar rats. Animal were divided into 2 groups of eight animals in each: Rats consumed distilled water (control group). Group 2: Rats consumed a solution of sodium arsenite (100 ppm) daily (arsenic group). At the end of day 28 arsenic exposure, the enzyme level in rat liver and kidney tissues was measured using the assay kits. The remaining liver, kidney, and heart tissue were fixed in 10% neutral-buffered formalin and used for histological observation. Results: The results showed a significant decrease in values of glutathione peroxidase (GPx), superoxide dismutase (SOD), total antioxidant capacity (TAC) and catalase (CAT) in serum and tissue in kidney and liver rat (P < 0.05). But, malondialdehyde (MDA) levels were increased significantly (P < 0.05). Arsenic caused severe degenerative changes in tubular cells and acute tubular necrosis, hepatocyte cell degeneration, severe hemorrhage, and infiltration and formation of Kupffer cells nodules, fragmentation, and degeneration of muscle fibers with pyknotic nuclei in heart tissue. Conclusions: The finding of the present study revealed that the administration of Sodium arsenite caused significant oxidative stress, decreased antioxidant enzymes activity and severe tissue damage.

“…Reports of skin lesions and hepatomegaly due to persistent use of drinking water with high concentrations of arsenic in West Bengal appeared in the 1980s [244,245]. In more recent years, several authors have described health effects including skin lesions, respiratory disease, impaired cognition, and cancer due to arsenic exposure in Bangladesh and other countries [241,[246][247][248][249]). …”

Rice production is susceptible to damage from the changes in temperature and rainfall patterns, and in the frequency of major storm events that will accompany climate change. Deltaic areas, in which millions of farmers cultivate from one to three crops of rice per year, are susceptible also to the impacts of a rising sea level, submergence during major storm events, and saline intrusion into groundwater and surface water resources. In this paper, I review the current state of knowledge regarding the potential impacts of climate change on rice production and I describe adaptation measures that involve soil and water management. In many areas, farmers will need to modify crop choices, crop calendars, and soil and water management practices as they adapt to climate change. Adaptation measures at the local, regional, and international levels also will be helpful in moderating the potential impacts of climate change on aggregate rice production and on household food security in many countries. Some of the changes in soil and water management and other production practices that will be implemented in response to climate change also will reduce methane generation and release from rice fields. Some of the measures also will reduce the uptake of arsenic in rice plants, thus addressing an important public health issue in portions of South and Southeast Asia. Where feasible, replacing continuously flooded rice production with some form of aerobic rice production, will contribute to achieving adaptation objectives, while also reducing global warming potential and minimizing the risk of negative health impacts due to consumption of arsenic contaminated rice.

“…With the identification of arsenic contamination in groundwater in 1993 and arsenicosis patients in 1994, a large proportion of the population found themselves to be without access to safe drinking water. Estimations showed that about 50 million people in Bangladesh were at risk of arsenic exposure through drinking arsenic-contaminated water [1,2,3,4]. STWs of almost all the districts of Bangladesh, except for those in the hilly and terrace upland areas, were reported as arsenic contaminated.…”

“…Directorate General of Health Services (DGHS) using WHO arsenicosis case diagnosis and management protocol, trained the health workers in screening for suspected arsenicosis cases based on classical dermatological skin manifestations. The suspected cases were examined by trained physicians and finally by 2012 about 66,000 clinically confirmed arsenicosis cases were identified [1,2,6,12,13]. These patients were managed by cessation of exposure, increased intake of protein and vitamins AEC rich food, application of keratolytic ointment (if applicable), and vitamins AEC supplementation [1,6,12].…”

“…Cancers may occur on multiple sites, especially lungs, skin, bladder, liver and prostate [14,15]. In Bangladesh, the association of occurrence of cancers and NCDs with chronic exposure to arsenic had been evident in many studies [1,6]. However, in Bangladesh, most of the arsenicosis patients were found in the mild and moderate stages of the disease [1,2,6].…”

Background: Arsenic contamination in groundwater of Bangladesh was first detected in 1993 and still a major public health problem in the country. In 1997, Samta was identified as a severely arsenic contaminated village and many villagers were found to suffering from arsenicosis. Methods: A series of surveys were carried out in Samta village in the years 1997, 2002, 2008 and 2017 to assess the situation of arsenic contamination and the status of arsenicosis in the village. The water sources and the entire population of the village were included in the study. Results: In 1997 about 87% of the shallow tubewells in Samta village were arsenic-contaminated and 10.1% villagers had arsenicosis. Twenty years later in 2017, about 90% shallow tubewells were arsenic contaminated, 39 deep tubewells and a pond sand filter were installed in the village and 2.3% of the villagers had arsenicosis. On an average 43.8% arsenicosis patients had recovered from the illness and condition of 21.2% patients had deteriorated or remained unchanged. During the 20-year period 37(6.1%) arsenicosis patients and 185(1.6%) non-arsenicosis villagers had died. The main cause of death among arsenicosis patients was cancer (40.5%) and among non-arsenicosis villagers the cause was geriatric problem (11.8%). The mean age at death was 57.6 years and 61.2 years respectively. Conclusion: In twenty years, measures were undertaken to make available arsenic-safe water options and people were motivated to stop the use of arsenic-contaminated water and to increase the intake of protein and vitamin AEC rich food. Recovery had occurred in a substantial proportion of patients.
