AbstractBeryllium-7 (Be-7), as a potentially powerful tracer, was widely used to document soil redistribution and identify sediment sources in recent decades, but the quantity and distribution of Be-7 in vegetation, soil, sediment and runoff on the Loess Plateau have not been fully described. In this study, we measured Be-7 in vegetation, soil, sediment and runoff on the northern Loess Plateau of China and analyzed its variations during the rainy season to assess the potential of the Be-7 method for documenting soil redistribution and identifying sediment sources in a wide range of environments. The results indicated that vegetation, soil, and sediment samples showed higher levels and larger variations of Be-7 activities during the rainy season. The drying plants showed Be-7 mass activity that was more than three times higher than that of living and semi-decomposed plants. Be-7 mass activity in plants and sediment was much higher than in the soil. Be-7 activity in runoff water with a few submicron suspended particles varied slightly and was far lower than in plant, soil and sediment samples. The cumulative precipitation generally determined Be-7 inventory held by plants and soil. An inverse relationship was found between the Be-7 mass activity in sediment and the sediment amount. Globally, approximate 30% of the total Be-7 was held by plants in both the herbaceous and subshrub plots. Approximate 10% of the total Be-7 was lost with sediment from the bare plot. A very small proportion of Be-7 (1.18%-3.20%) was lost with runoff, and the vast majority of Be-7 was retained in the slope soil at the end of rainy season. Vegetation cover and soil erosion significantly affected the spatial distribution and variations of the Be-7 inventory in soil, providing a necessary condition for the development of a Be-7 method to document soil erosion on slopes with vegetation.
