Hi all…the World Health Agency (WHO) has developed some background documents for cyanotoxins which will be included in the second addendum to the fourth edition of the WHO’s Guidelines for Drinking-water Quality and is looking for comments by Jan 12, 2020. The cyanotoxins include anatoxin-a, cylindrospermopsin and one which isn’t on the North American regulatory radar to any great extent, saxitoxin. There is some brief discussion on ‘Analytical methods and achievability’ and ‘Treatment methods and performance’.
Chemical background documents for the development of the Guidelines for drinking-water quality: Available for comment
The “WHO is preparing a number of background documents for selected chemical hazards in drinking-water. These will inform the development of the second addendum to the fourth edition of the WHO’s Guidelines for Drinking-water Quality (GDWQ). Revised background documents are ready for review for the cyanotoxins anatoxin-a, cylindrospermopsin and saxitoxin. Comments on the background documents should be sent to email@example.com by 12 January 2020.”
