抄録: Rain water contains various insoluble particles. Detection and observation of in-soluble organic particles in rain water with a fluorescence microscope has been studied. A laser scanning microscope was used for observation of fluorescent particles. Rain water was collected from July 1996 to December 1996 in Shizuoka, and 17 rain water samples were collected. Fluorescent particles in rain water were characterized as organic matter using a Fourier transform infrared (FTIR) microscope. It was found that about 90% of fluorescent particles in rain water were organic matter and about 70% of non-fluorescent particles in rain water was inorganic matter, and also it was found that some of fluorescent particles were biological particles. These results indicate that most fluorescent particles in rain water reflect organic particles. Some fluorescent particles in rain water are cedar pollen and pine pollen, but the compound or material of majority couldn't be identified. The mean concentration of fluorescent particles with radii 2 μm≦ r < 128 μm in rain water was 960 cm^<-3>. The number of fluorescent particles in rain water was influenced by the amount of rainfall and wind speed, and the some cases is also influenced by rainfall intensity.
