Working Group Summary

The Environmental Geochemistry working group has organized the International Symposium on Environmental Geochemistry (ISEG) since the late 1980s. The initial local symposium was held in Finland. After that, plans were made to organize a regular international symposium series. 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 organization 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. The most recent ISEG conference was held in Aveiro, Portugal in 2025.

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)
