WWARN would like to thank all those scientists who contributed data, unpublished information or PhD theses to the database. We are also grateful to everyone who has given advice and contributed to beta-testing during the development of the AQ Surveyor.

The French Ministry of Foreign and European Affairs (FSP Mekong Project) provided financial support.

We welcome additional information, corrections or comments from authors. Contact Céline Caillet (WWARN AQ Coordinator) at medicinequality [at] wwarn [dot] org.
