“…Arsenic is ubiquitous in the environment, with human exposure occurring through dietary intake, inhalation of contaminated air, and ingestion of contaminated soil/dust (Joseph et al 2015). However, the consumption of arsenic-contaminated drinking water is the major exposure route that affects more than 200 million people worldwide, including approximately 77 million in Bangladesh and 17 million in the United States (US) (BBS/UNICEF 2014; IARC 2004).…”

Background Chronic arsenic exposure is a public health concern in many parts of the world, with elevated concentrations in groundwater posing a threat to millions of people. Arsenic is associated with various cancers and an array of chronic diseases; however, the relationship with adverse pregnancy outcomes and child mortality is less established. Objectives We evaluated associations between individual-level prenatal arsenic exposure with adverse pregnancy outcomes and child mortality in a pregnancy study among 498 women nested in a larger population-based cohort in rural Bangladesh. Methods Creatinine-adjusted urinary total arsenic concentration, a comprehensive measure of exposure from water, food, and air sources, reflective of the prenatal period was available for participants. Self-reported pregnancy outcomes (livebirth, stillbirth, spontaneous/elective abortion) were ascertained. Generalized estimating equations, accounting for multiple pregnancies of participants, were used to estimate odds ratios and 95% confidence intervals in relation to adverse pregnancy outcomes. Vital status of livebirths was subsequently ascertained through November 2015. Cox proportional hazards models were used to estimate hazard ratios and 95% confidence intervals in relation to child mortality. Results We observed a significant association between prenatal arsenic exposure and the risk of stillbirth (greater than median; adjusted OR=2.50; 95% CI=1.04, 6.01). We also observed elevated risk of child mortality (greater than median; adjusted HR=1.92; 95% CI=0.78, 4.68) in relation to prenatal arsenic exposure. Conclusions Prospective studies should continue to evaluate prenatal and early life health effects of arsenic exposure and arsenic remediation strategies for women of child-bearing age.

“…The high rice consumption in South East Asia has become the preponderant arsenic source for people not suffering from contaminated groundwaters. The average daily rice consumption for an adult in Bangladesh ranges from 400 to 650 g. This is one of the highest per capita rice consumption figures in the world (Joseph et al 2015; Ahsan and Del Valls 2011). Irrigation of rice fields is mandatory in the dry season, also called “boro”.…”

“…However, there seems to be the risk of adultering the raw milk by diluting it with contaminated water. Due to the limited number of studies from Bangladesh and, more importantly, the limited sample sizes in almost all of these studies, a conclusive species-specific observable range for arsenic in edible plant parts (except rice) and animal-origin food cannot be defined as yet (Joseph et al 2015). …”

The Arsenic Contamination of Drinking and Groundwaters in Bangladesh: Featuring Biogeochemical Aspects and Implications on Public Health

Arsenic is a widespread contaminant of drinking and groundwaters in the world. Even if these contaminations have a geogenic origin, they often are exacerbated by anthropogenic activities. This is particularly true for the Bengal delta. Millions of people in Bangladesh are consuming drinking water with arsenic concentrations ≥ 50 µg/L. Their drinking water supply is based on groundwaters extracted by pumping wells, which were part of a well-drilling program by the United Nations. The intention was to provide the people with groundwater instead of surface water due to its critical hygienic conditions. Unfortunately, many wells extract the groundwater at depths where arsenic concentrations are highest. Arsenic is being dissolved from the aquifer by biogeochemical processes that are fueled by the presence of high amounts of organics in the Bengal delta sediments. This problem was not encountered at the time due to a lack of chemical analyses of the waters.

Amenazas para la salud en el Río Sonora: análisis exploratorio de la calidad del agua reportada en la base de datos oficial de México. Rev Univ Ind RESUMENEl 6 de agosto de 2014 ocurrió en el Río Sonora, México, lo que fue llamado "el peor desastre ambiental de la industria minera del país" cuando la mina Buenavista del Cobre derramó alrededor de 40,000 metros cúbicos de lixiviado ácido. Con el fin de avanzar en el conocimiento de las consecuencias de este evento, se analizó la base de datos del monitoreo de la calidad del agua subterránea que aparece en el portal electrónico del Fideicomiso Río Sonora. Por las implicaciones que este evento tiene para la salud, los valores reportados se confrontaron con los límites máximos permisibles establecidos en la Norma Oficial Mexicana vigente. Asímismo, para enriquecer la discusión, se analizó el caso del arsénico, comparando los valores reportados en relación con la Norma Mexicana y con la Guía de calidad para el agua de la Organización Mundial de la Salud.Palabras clave: Calidad del agua, Río Sonora, Buenavista del Cobre, vertimiento. ABSTRACTOn August 6th, 2014, the event labelled as the "worst environmental disaster of the mining industry in Mexico" ocurred in the Sonora River, when Buenavista del Cobre mine spilled around 40,000 cubic meters of an acidic leachate. In order to expand our knowledge of the consequences of this event, the water quality monitoring data base was analyzed for groundwater from the Río Sonora trust fund webpage. Due to the health relevance of the spill, the reported data was compared to the established maximum allowance values of Mexican regulations. Furthermore, for an enhanced discussion, the case of arsenic was also analyzed, comparing the data with Mexican regulations as well as with the WHO guidelines for drinking water.
