Finalization of the document "Cyanobacteria, their toxins, water and health" : report on a WHO editorial meeting, Bad Elster, Germany 10-15 November 1997

A process of rolling revision of the WHO Guidelines for Drinking-water Quality was begun in 1995, and is to include aspects of risk management as well as risk assessment. The manuscript in preparation, which will contribute to this process, has been retitled Toxic Cyanobacteria in water: a guide to public health significance, monitoring and management and is to be produced as a book. A group of 21 experts met at the Research Department of the Institute for Water, Soil and Air Hygiene in Bad Elster, a WHO collaborating centre for research on drinking-water hygiene, and made detailed recommendations on the content and format of the book and on its publication. The programme of work adopted at the meeting will lead to publication by the end of 1998
