Jan 16, 2019 The WHO Guideline in Retrospect. The World Health Organization (WHO) published the first version of International Standards for Drinking Water in 1953 which included As in the category of toxic substances and a maximum allowable concentration of 200 g/L was proposed.
Apr 6, 2022 Abstract. Evidence-based public health policy often comes years or decades after the underlying scientific breakthrough. The World Health Organizations (WHOs) provisional 10 g/L arsenic (As) drinking water guideline was set in 1993 based on analytical achievability.
May 1, 2021 open access. Highlights. . Nearly 108 countries of the globe affected by arsenic contamination in groundwater. . More than 230 million people, including 180 million from Asia are at risk. . More than 90% of arsenic pollution is inferred to be geogenic. . Prolonged consumption of arsenic-contaminated groundwater results in severe health issues.
(Photo and original story: Asia Arsenic Network) Drinking water containing arsenic can lead to skin lesions and internal cancers. The effects may be delayed for years. In Bangladesh, hundreds of thousands of people suffer from chronic arsenic poisoning and many more may eventually be affected. Arsenic is found in ground-water in all continents.
