Response of sorption properties to long-term soil management
Abstract
For many pollutants soil acts as the main sink in the terrestrial environment. Interaction of pollutants with mineral and organic soil constituents, microbes and plant roots determine their medium- and long-term behaviour. Soil organic matter (SOM) governs many soil properties and processes. SOM quantity and quality shows a considerable site variation caused by levels of OM input, related biological activity, overall nutrient status of the soil, vegetation, climate and soil minerals. SOM has a major influence on the adsorption properties of soils both by providing ample sites for adsorption and complexation of cations and anions and by altering the general chemical properties of soils. The only way to investigate the SOM effect isolated and possible concrete interactions with the unaltered mineral soil constituents is to use soils from long-term experiments, in which the SOM was altered, but the mineral phase was considerably less influenced by the long-term management. Sorption of a pesticide, which was used as first model substance (MCPA) was significantly altered by SOM levels. It is suggested to examine the impact of different management (fertilization, manures,...) of arable land and different landuse (permanent pasture vs. arable land) on the sorption properties for: i) selected organic compounds (pesticides, polar and apolar substances) ii) heavy metals iii) radionuclides (Cs, Sr)A possible correlation of SOM turnover/buildup and sorption sites should be evaluated during the project by various methods. The outcome of the experiments will determine the effect of different treatments on the sorption behavior. Analysis of the experimental data and comparison of the sorption and leaching behavior to mineral and organic soil properties, structure and properties of the organic compounds and properties of the heavy metals and radionuclides should reveal the effect to long term treatments on arable soil systems. Thus, such sorption experiments allows to generate a set of data which can be used both to (i) improve our recent knowledge regarding sorption behavior of the investigated analytes and (ii) to assess the influence of certain long term treatments on the migration behavior of selected pollutants. Comparison of our calculated data with experimental data will show how far a quantitative structural adsorption relationship can be applied to our system. Results from our QSAR (Quantitative Structure Activity Relation) model will be related to other existing soil sorption models, which obtained their input data from experimental data (e.g. log Pow) or quantum chemical descriptors.
