摘要
The input and output fluxes of As in farmland soils of the Hebei Plain were studied. By integrating various factors, the authors took the atmospheric wet and dry depositions, irrigation water and fertilizers as As inputs and the seeds of crops as As output for the study. It is indicated that the atmospheric wet and dry deposition is the most important route, while the irrigation and fertilizer fluxes are much lower. These 3 routes have the contributions of 53.1%, 28.9% and 18.1% of As in soils, respectively. It is estimated that the proportion of annual net As increment in soils of farmland is very small, so outside-sourced As will cause little change in As distribution in soils in a short time.
