16. Перейти на первую страницу ARSENICS PROBLEM IN THE WORLD WHO's activities on arsenic In 1963 the standard was estimated to be 0.05 mg/L. In 1984, this was maintained as WHO's "Guideline Value"; and many countries have kept this as the national standard or as an interim target. According to the last edition of the WHO Guidelines for Drinking-Water Quality (1993): Inorganic arsenic is a documented human carcinogen. 0.01 mg/L was established as a provisional guideline value for arsenic. Based on health criteria, the guideline value for arsenic in drinking-water would be less than 0.01mg/L. Natural arsenic pollution is a global phenomenon for 70 countries on all continents, except Antarctica,. In recent decades about 140 million people worldwide have been exposed to drinking water containing more than 10 μg/L of arsenic.”
