AbstractThe deposition flux of Be-7 was measured in the range from 0.4 to 5.2 Bq m(-2) d(-1), with a mean value of 2.6 Bq m(-2) d(-1), during the period of May 31, 2009-May 31, 2010 in the Three Gorges Reservoir region, China. The low annual deposition flux of Be-7 was probably due to the adsorption of Be-7 within high altitude clouds and the Qinling-Daba Mountain's barrier and blocking effects on the cold air during winter months. There was a seasonal trend for Be-7 deposition, showing a spring maximum and winter minimum, which may be attributed to the seasonal folding of tropopause in spring and little rainfall amount in winter. A strong positive correlation (R (2) = 0.67) between Be-7 deposition flux and rainfall was observed. The depth distribution of Be-7 in undisturbed purple soil profiles suggested that the nuclide was mainly distributed within the top 20.0 kg m(-2) (similar to 1.5 cm) of soil in depth and the maximum concentration occurred at a depth of 3.0 kg m(-2) (similar to 0.2 cm), then the concentration declined quickly and exponentially with depth. The seasonal inventories of Be-7 in soils were consistent with the values calculated from the atmospheric fluxes, which shows a great potential for using Be-7 as a tracer to assess soil redistribution in purple soil areas of China.
