Due to a lack of quantitative analytical methods, appropriate methods based on chromatography coupled with mass spectrometry were developed or adapted for all substances in a first step. In the next step these methods were used to detect the compounds inositol hexakisphosphate and methylphosphonic acid in samples from the aquatic systems mentioned above.
