AbstractIn many ecosystems, especially in siliceous soils, the mobile anión balance controls the entire ionic equilibrium. However, the equilibrium of the mobile anión cycle is very fragüe, and many factors— abiotic, biotic and, above all, human—constantly disturb it. This paper reports a study of the principal anions found in the surficial layer of soils situated over sedimentary substrates in a continental Mediterranean environment, primarily in semiarid regions. Human (deforestation) and animal activities over decades (overgrazing, trampling) have altered these soils to different degrees. Recently, their use in some cases as landfills for solid waste has become one of the major causes of disturbance. Comparisons are made in order to highlight the differences among soil types and those between the disturbed sites and surroundings. The results show that natural soils are poor in soluble anions. It is also possible to distinguish clear differences in the average concentrations found in three different natural substrates. Finally, there are notable elevated concentrations of Cl and SO4 in landfill soils.
