摘要：
Fluorescence Excitation-Emission Matrix spectroscopy combined with parallel factor analysis was employed to monitor water quality and organic contamination in swimming pools. The fluorescence signal of the swimming pool organic matter was low but increased slightly through the day. The analysis revealed that the organic matter fluorescence was characterised by five different components, one of which was unique to swimming pool organic matter and one which was specific to organic contamination. The latter component had emission peaks at 420 nm and was found to be a sensitive indicator of organic loading in swimming pool water. The fluorescence at 420 nm gradually increased during opening hours and represented material accumulating through the day. (C) 2011 Elsevier Ltd. All rights reserved.
