Chemical hazards in drinking-water - pyriproxyfen
Pyriproxyfen is considered in the WHO Guidelines for Drinking-water Quality.
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
Pyriproxyfen is included in the plan of work of the rolling revision of the WHO Guidelines for Drinking-water Quality.
The Guidelines for Drinking-water Quality Working Group meeting (Geneva, 2005) agreed that allocation factors of 20% rather than 10% should be used for WHO/PES pesticides, which are deliberately added to water for public health purposes. Pyriproxyfen is the only WHO/PES pesticide for which there is currently a guideline value and which uses an allocation factor of 10%.
Revised background document "Pyriproxyfen in Drinking-water", together with an additional background document addressing the use of Pyriproxyfen for Vector Control in Drinking-water Sources and Containers for the second addendum.
Progress to date
The Guidelines for Drinking-water Quality Working Group meeting (Geneva, 2005) agreed on a plan of work. The Guidelines for Drinking-water Quality Working Group meeting (Geneva, 2006) agreed to revise the draft background document following discussions with the WHO Vector Ecology and Management Programme.
The background document and summary statement are now available.
