Format: Oral Topical Session
Keywords: Humic substances

Session Description: Humic fractions prepared through chemical extractions have been used for centuries to study NOM in terrestrial and aquatic systems. Recently critics have asserted that extracted humic substances are so altered by the extraction procedures that they have no environmental meaning and are therefore irrelevant for NOM studies. A variety of issues will be debated by proponents and opponents of humic substances in the morning and afternoon sessions and a panel discussion.
