ResumoIdentification of volatile odorous compounds is reported from blooms of the Cyanobacteria Oscillatoria, Anabaena and Microcystis and the Chrysophyte Synura in South Australian reservoirs and River Murray water. Chemical "fingerprinting" of this kind may be used to assist in the development of removal or treatment techniques to minimise or eliminate the aesthetically unpleasant effects of algal blooms on drinking water quality. Volatiles were concentrated using the closed loop stripping (CLS) method and analysed by gas chromatography/mass spectrometry (GC/MS). Compounds isolated from the Cyanobacteria included geosmin, 2-methylisoborneol, sesquiterpenes, β-cyclocitral, 3-methyl-1-butanol and 6-methyl-5-hepten-2-one. The compound responsible for the dominant cucumber odour of Synura petersenii was identified for the first time as trans-2, cis-6-nonadienal.
