Description

<p>In 2004, musty odor causing compounds, geosmin and 2-methylisoborneol, were newly added into the water quality standards for drinking water, and has enhanced the countermeasures by water supply utilities. While, the population affected by the taste and odor issues was within the range of 100~450 million during FY2001~2013, and now under the tendency of increasing. Komárek et al. presented a new classification system of Cyanophyceae. The musty odor producing Cyanophyceae should be also organized based on the new classification with consistency of the conventional generic and species name. Molecular formulae of fishy smell causing compounds were estimated by utilizing the recently innovated mass spectrometry combined with multivariate analyses.</p>
