<\/span>The term \u201cnatural organic matter\u201d (NOM) is normally used to designate all the organic matter in a reservoir or natural ecosystem other than living organisms and compounds of man-made origin. The NOM found in natural waters possesses a large variety of properties and is composed of an extremely complex mixture of compounds, most of which have not yet been identified.\u00a0Because of the diversity of the natural processes of synthesis and degradation, the number of constituents in this mixture can be considered to be \u2018infinite\u2019, and therefore there is little hope of completely separating and identifying them. Consequently, studies of NOM have nearly always been concerned not with pure compounds but rather with groups of compounds separated from the initial mixture, or simply observed, by means of different techniques.\u00a0Some groups, such as humic-type compounds, have received a lot of attention.<\/p>\n

My research interests are mostly focused on the quantification<\/strong> of the different types of NOM. You can find the description of the technique developed in collaboration with Fran\u00e7ois Quentel (UBO, France) for the quantification of the humic fraction<\/strong>:<\/p>\n
