Abstract

Stable C-O isotopic composition of loess samples for TSP, PM₁₀, PM_2.5, and PM₁ at five sites (Yulin, Yanchi, Huanxian, Luochuan, and Xi'an) in Chinese Loess Plateau are examined. The average δ¹³C and δ¹⁸O abundances were -6.00‰ and -8.30‰ in TSP, -6.05‰ and -8.22‰ in PM₁₀, -6.07‰ and -8.33‰ in PM_2.5, and -6.00‰ and -8.28‰ in PM₁, respectively. Little differences were found for δ¹³C and δ¹⁸O abundances in four size fractions. The differences of δ¹³C between the averages of fugitive dust and bulk soil were smaller than 2‰ at five locations, which implied that the isotopic composition of bulk soil (surface soil) can be used as substitute of fugitive dust carbonate in dust source apportion study. The distribution of CO₃-C, δ¹³C and δ¹⁸O in fugitive dust shows that only δ¹³C is a powerful tracer of source regions. A database about the δ¹³C distribution in soil carbonate in major source regions of Asian dust was summarized for source apportion study of atmospheric dust.
