本文データはCiNiiから複製したものである。Three-dimensional excitation emission spectrometry was applied to the characterization for the water-soluble fluorescent substances (WSFS) in rainwater and airborne particulate matter. The contour plots of EEM spectra of WSFS in rainwater showed one sharp peak at an excitation wavelength 300-305nm/emission wavelength 405-415nm. The fluorescence intensity of WSFS in rainwater decreased with rainfall amount. The peak position of the WSFS in airborne particulate matter was in good agreement with the peak position of WSFS in rainwater. The fluorescent intensity of the water-soluble component was affected by the extraction operating conditions. The fluorescent substances in the water-soluble components of airborne particulate matter were defined as the filtrate obtained using a 0.45μm membrane filter after immersion in ultrasonic wave irradiation for 20 minutes. The spectrum patterns of rainwater and WSFS in airborne particulate matter were almost coincided with WSFS in the NIES standard reference material.
