摘要

The ~87Sr/~86Sr ratios in rain at three sites in Japan were about 0.706 to 0.712, whereas those at one site I central Korea were higher (0.711 to 0.716), reflecting the difference in geology between the two countries. Because the ~87Sr/~86Sr ratio of exchangeable sites in soil minerals are indistinguishable from those of associated plants, aerosol Sr originating from both can be grouped together as plant-derived Sr.
