Abstract:
... Over the last decade, computed tomography (CT) images have been used increasingly to gain a more complete understanding of the microscale parameters that control the soil processes. Images that are used for that purpose typically are subjected to a number of successive treatments. This article evaluates for a sandy-loam soil, the impact of two CT scan resolutions (26 and 54 μm), three noise reduct ...

Abstract:
... Lead (Pb) complexed with dissolved organic matter (DOM-Pb) is a dominant Pb species in soils, but it is not clear that DOM-Pb is stably immobilized by hydroxyapatite. This study investigates how DOM-Pb is immobilized by hydroxyapatite in both aqueous solutions and soils. A sorption test showed that 69.5% of DOM-Pb is removed in an aqueous solution, but less DOM-Pb is retained by hydroxyapatite com ...
