  Citation × Citation Citation Abstract Copy Title: Persistence of aromatic compounds in soils and sediments : a molecular perspective Author: Keiluweit, Marco This thesis explores open questions regarding molecular forms and interactions of natural and synthetic aromatic compounds present in soils and sediments. Plant biomass-derived black carbon (biochar) generated through incomplete natural and anthropogenic combustion processes is a major source of aromaticity in terrestrial ecosystems. Chapter one represents a detailed account of the variations in the chemical and physical nature of aromatic components of char black carbon. Despite reports showing that aromatic compounds are degraded with relative ease, they are relatively persistent in subsurface environments. Chapter two highlights unique mechanisms of interaction of aromatic π-systems (i.e., π-electron donor-acceptor interactions) by which aromatic molecules adsorb to mineral and organic phases. It is discussed how these interactions may contribute to the sequestration of aromatic compounds in soils and sediments.
