    Geosmin (GSM) and 2-methylisoborneol (MIB) are semi-volatile compounds produced by cyanobacteria in surface waters. These compounds present problems to the drinking water industry and in aquaculture because they can taint ...
  • Detection, analysis, and photocatalytic destruction of the freshwater taint compound geosmin 

    Bellu, Edmund (The Robert Gordon University Faculty of Health and Social Care. School of Life Sciences., 2007-04)
    A significant issue affecting the aquaculture and water industries is the presence of off-flavour compounds in water, which cause problems by imparting an undesirable earthy/musty flavour and smell to water and fish. ...
  • Mechanistic and toxicity studies of the photocatalytic oxidation of microcystin-LR. 

    Liu, Iain; Lawton, Linda A.; Cornish, Benjamin J. P. A.; Robertson, Peter K. J. (Elsevier http://www.elsevier.com/wps/find/journaldescription.cws_home/504091/description#description, 2002-05-31)
