AbstractMusty and earthy odors frequently characterize the source water and fish of the Xionghe Reservoir in China. Although odorous compounds and odor-producing cyanobacteria have been analyzed in surface water, potential odorants in sediments and their contribution to the water body have remained uninvestigated. In this study, we examined the odorous compounds and possible odor-producers in the sediments and overlying water of Xionghe Reservoir from November 2007 to October 2008. High concentrations of geosmin (up to 5280.1 ng kg(-1) dw(-1)) were detected in sediments, and eight strains of Streptomyces isolated from sediments were verified as producers of geosmin and/or 2-MIB in M liquid medium by HSPME-GC-MS. Geosmin concentrations in the overlying water were correlated with those in the sediments (r = 0.838, p <0.05). In vitro studies showed that geosmin in the overlying water was released from the sediment, and that within 12 days the amount released from the sediment was 21.4-51.4%. Concentrations of geosmin in sediments were positively correlated with organic matter (r = 0.642, p <0.01), total nitrogen (r = 0.606, p <0.01) and Chi a (r = 0.674, p < 0.01), and were negatively associated with temperature (r = -0.425, p <0.05). This study indicates that odorous compounds that are released from sediments should be taken into account when assessing the sources of these odorants in waters. (C) 2010 Elsevier Ltd.
