Chemical hazards in drinking-water - temephos
Temephos is included in the plan of work of the rolling revision of the WHO Guidelines for Drinking-water Quality.
The background document and summary statement for the fourth edition are now available :
The GDWQ FTF meeting (Geneva, 2003) recommended that temephos be referred to JMPR with high priority (as it is a WHO/PES pesticide applied to water for public health purposes) and that a background document be prepared as part of the rolling revision.
Background document and summary statement for publication in the Fourth Edition.
Progress to date
The GDWQ WG meeting (Geneva, 2004) agreed to add temephos to the rolling revision and decided on a plan of work. No progress had been made on this item by the time of the GDWQ WG meeting (Geneva, 2005). The GDWQ WG meeting (Geneva, 2006) agreed to prepare a background document following discussions with the WHO Vector Ecology and Management Programme. The GDWQ WG meeting (Berlin, 2007; Singapore 2008) agreed on a path forward towards finalizing the background document.
