Publisher Summary Toxicology first came into its own in Finland in the late 1970s. The first full-time professorship in toxicology (precisely in toxicology and pharmacokinetics, changed later to toxicology) was founded at the University of Kuopio, Department of Pharmacology and Toxicology in 1976. As to information sources in toxicology in Finland, most essential information can be gained through the Internet. Fewer books are currently being published on toxicological topics. This chapter focuses on current information considered most useful—the newest relevant sources. As to descriptions of the organizations, the perspective has been wide because it is often more important to know where to find the information than precisely what can be found there. Internet search engines are powerful tools for finding documents if one has a reliable reference. Most of the listed digital sources exist in both Finnish and English versions, and others include English summaries. Contact information is provided where feasible but it mostly can also be located from digital sources.
