Chemical hazards in drinking-water - microcystin-LR
Microcystin-LR is considered in the WHO Guidelines for Drinking-water Quality. You can link from here to:
The Guidelines for drinking water quality also consider for individual chemicals:
Aspects of analytical achievability [Section 8.3, pp. 157-166]
Technical achievability (through treatment and other means) [Section 8.4, pp 166-184]
Rolling revision of the WHO Guidelines for Drinking-water Quality
Analytical and technical achievability for microcystin
Section 8.3 of the Guidelines for Drinking-water Quality provides information on the analytical achievability of all chemicals in the Guidelines for Drinking-water Quality except for microcystin. This needs to be included.
Additional text for section 8.3 (analytical) and section 8.4 (treatment) of the Guidelines for Drinking-water Quality, for inclusion in second addendum of Third Edition
Progress to date
The Guidelines for Drinking-water Quality Working Group meeting (Geneva, 2004) agreed to a plan of work. The Guidelines for Drinking-water Quality Working Group meeting (Geneva, 2005) reviewed and approved the text for the second addendum and agreed to include a treatment section in the second addendum, which has already been prepared.
The draft document is now available for review. Comments are welcome following the format on the comment sheet, below.
Comments on the draft sections should be sent before 1 August 2007 to firstname.lastname@example.org
