THE LEACHING AND MOVING OF 125 I IN SUBTROPICS SOILS OF SOUTH CHINA

Lui Xiaohong\ Liu Qiongying\ Kuang Yanhua (The laboratory of biophysics, South China Agricultural University, Guangzhou\ 510642) Cai Hong (Department of CSE, The Hong Kong Polytechnic University) Peter H. Yu (Department of ABCT, The Hong Kong Polyt  
The leaching and vertical moving of 125 I in subtropics soils of south China were studied by soil volume. The results showed that after passing through 20cm soil volume, the content of 125 I in leachate of laterite was 5.26% of labelled amount and 11.05% in leachate of paddy soil. After leaching 88.03% of 125 I in laterite volume remained in the layer of 0~10 cm, while 92 21% in paddy soil volume. 27 days after vertical moving in soil volume, 125 I distributed in every layer, most of it remained in the topsoil, 91.67% of 125 I in laterite and 83.98% in paddy soil remained in the top layer (0~2cm).
