Chemical hazards in drinking-water - dichlorvos
The draft document is now available for review. Comments are welcome following the format on the comment sheet, below.
Comments on the draft background document above should be sent before 30 May 2007 to firstname.lastname@example.org.
Dichlorvos is included in the plan of work of the rolling revision of the WHO Guidelines for Drinking-water Quality.
Although the Berlin Coordinating Committee meeting (2000) suggested that dichlorvos is unlikely to occur in drinking-water and therefore should not be included in the GDWQ, the Chemical Aspects WG meeting in Tokyo (2002) recommended that it be considered as part of the rolling revision process based on the 1993 JMPR assessment.
Short background document for second addendum.
Progress to date
Guidelines for Drinking-water Quality Working Group meeting (Geneva, 2004) and theGuidelines for Drinking-water Quality Working Group meeting (Geneva, 2005) agreed to review the occurrence data for dichlorvos in order to determine whether it satisfies the criteria for inclusion and should be added to the rolling revision. The Guidelines for Drinking-water Quality Working Group meeting (Geneva, 2006) agreed that a short background document on dichlorvos should be prepared for the second addendum.
