Transport of Organic Molecules in environment insights from retardation in sedimentary rocks.

Abstract : Organic molecules are widely studied in environmental sciences, marine chemistry, soil- and geosciences. Among them, anthropogenic organic matter (AOM) can be potentially released from hazardouswaste and migrate through geological rock formation or soils. AOM refers to a wide range of compounds,including both ionic and neutral molecules, polar and apolar molecules. The ionic polar molecules are highly soluble in water and more mobile in soils and rocks. The neutral (poly)aromatic compounds are less soluble, often absorbed by soil organic matter, but also more resistent against (bio)degradation. For all these compounds, adsorption or absorption processes can slow down their migration in environmental conditions. Consequently, understanding retardation phenomena of soluble organic matter in rocks and soils is crucial for safety assements of waste storage, decontamination processes, ore extraction and remediation of soils.
