The extraction and fractionation of naturally occurring iodine from environmental matrices followed by a spectrometric measurement is the most frequently used method for iodine determination. Nowadays, the inductively coupled plasma mass spectrometry (ICP-MS) represents the most common and reliable method of the total iodine content determination in environmental samples and foodstuff. Other methods such as liquid or gas chromatography which, besides iodine quantification, enable to distinguish individual iodine species are used as well. The aim of this paper is to summarize the most widely used analytical and sample preparation methods for the iodine determination in environmental matrices focused on soil and plant tissues.
