抄録

Laser Raman microprobe was applied for the analysis of anthophylite asbestos particles in environmental particulates. A Molecular Optics Laser Examiner (MOLE), Instrument S.A., was used for the experiment with use of Ar ion laser of 514.5 nm, output power=(300450) mW and slit of 1000 μm or 1100 μm in width, measurement range, Δv=(2001400) cm-1. Sample powder was dispersed with acetone on a non-fluorescence microscopic glass plate and was served for observation. In the analysis in punctual illumination mode, anthophylite asbestos and anthophilite nonfibrous particles were identified from a sediment dust on a beam in an abandoned asbestos factory building in Fukushima Prefecture. The existence of carbonate and phosphate minerals and alite component of cement was suggested from their Raman peaks. From a dust sample obtained from the back of a bench on a subway platform, no anthophylite Raman peaks were detected, but a spectrum of cellulose with a peak at 1090 cm-1 was observed. In the analysis in global illumination mode, Raman image at 674 cm-1 was obtained from anthophylite particle sample.
