Working Group Summary

The International Symposium on Environmental Geochemistry (ISEG) was started in the late 1980s. The initial local symposium on environmental geochemistry was held in Finland. After that, discussions came up in Uppsala,
Sweden to organise a regular international symposium series on ‘Environmental Geochemistry.’ The discussion between Olle Selinus of Linneaus University, Sweden (formerly Geological Society of Sweden) and Prof. Mats Olsson of the Swedish University of Agricultural Sciences in Uppsala led to the first truly international ISEG symposium. No organisation was behind this conference, but from the beginning a core group of three geochemical scientists provided leadership to these symposia: Prof. Iain Thornton, Ron Fuge and Olle Selinus. It was decided that the ISEG symposia would be held every 3 years resulting in meetings on almost every continent since 1991:

Despite the popularity of the ISEG symposia, they never had the support of any formal organization or association. Beginning in 2013, the IAGC became the official society sponsor of this very popular series. The ISEG is also sponsored by:

• The International Medical Geology Association (IMGA)
• The Society for Environmental Geochemistry and Health (SEGH)
