The most well-known example of a mercury poisoning in the Japanese bay Minamata showed already in the 50's of the last century the importance of mercury analysis. Especially the Hg monitoring in natural waters is from great importance, because mercury is enriched very high in the aquatic food chain. Methods for total mercury determination, developed in this work, are fully automated, fast and sensitive methods, with detection limits in pg Hg/L range and are suitable for the monitoring of Hg content in sea waters as well as in fresh waters. Moreover, a new method was developed for the sequential determination of Hg species. For the first time a separation of dissolved Hg(0) on gold/platin surface directly from the aqueous phase is used here. Mean while, this procedure was applied for a patent from Technische Universität München and the co-operation partner Analytik Jena AG. The fast and simple method supplies a determination of inorganic and organic mercury in natural waters in succession and is therefore an important novelty.
