Towards a Molecular-Scale Understanding of Sorption of Organic Pollutants to Soil

有机污染物在土壤中的毒性、迁移性和持久性在很大程度上取决于其在土壤有机质上的吸附。有机物的化学性质或质量不仅影响化学吸附的量，而且影响吸附的可逆性以及吸附和解吸的速率。到目前为止，只有大量的措施，土壤有机质化学已被认为是在吸附研究。该项目引入了新的光谱技术，首次在分子尺度上识别吸附分子的化学环境。这将有助于更好地预测污染物的迁移和降解。

The toxicity, mobility and persistence of organic pollutants in soils are in large part controlled by their sorption to soil organic matter. The chemical nature or quality of the organic matter affects not only the amount of chemical sorbed, but also the reversibility of sorption and the rate of sorption and desorption. Until now, only bulk measures of soil organic matter chemistry have been considered in sorption studies. This project introduces novel spectroscopic techniques that for the first time identify the chemical environment of sorbed molecules at the molecular scale. This will enable better prediction of pollutant transport and degradation.
