| Research Abstract |
PM_<2.5> aerosols have been collected at Fukue Is., Cape Hedo of Okinawa Is., and Chi-chi jima Is. to identify the relative source contribution of black carbon since 2009 autumn. Carbon isotope analysis for one-week averaged aerosol sample showed thatδ^<13> C in the black carbon collected at Fukue decreased below-26.0‰in summer but increased in autumn, winter and spring, suggesting that contribution of motor vehicle exhaust is high in summer and that of combustion from coal and C4 plant is high in the rest of the year. The analysis of Cape Hedo and Chi-chi jima Is. is still underway.
