Organic Contaminants in Riverine and Groundwater Systems

It is known for milleniums, that water is forming the principle base for the total biosphere including human beings ('Thales [of Milet] says that it [the nature of things] is water' Aristoteles, Metaph. 983 b20), Nevertheless, basically the anthropogenic activities and human requirements, in particular our enormous consume of chemicals, are affecting worldwide the aquatic environment on a rapidly increasing level. Consequently, huge scientific efforts, worldwide, focussed intensively on increasing the knowlegde about the state of pollution and on the most important processes harming the aquatic systems. The overall aim is the rehabilitation and protection of this unique and essential compartment. Environmental studies on riverine and groundwater systems are base research activities at the Institute of Geology and Geochemistry of Petroleum and Coal, RWTH Aachen University. This book summarizes the analytical and organic-geochemical work performed between 1998 and 2003 at this institute. All the individual studies and the corresponding results were separately published in various scientific journals. However, I felt the substantial need to combine these individual parts in order to reveal a comprehensive overview on all the different and novel aspects concerning the organic contamination of rivers and groundwater.

This book considers several novel aspects on the anthropogenic contribution to the organic contamination of the aquatic systems.

Texte du rabat

This book reviews a selection of organic-geochemical investigations, dealing with the characterization and environmental behaviour of organic contaminations of German river and groundwater systems. Topics include comprehensive non-target screening as well as isotope analysis of contaminants in water and sediments, detailed characterisation of bound residues, recording riverine pollution histories and an extensive application of the anthropogenic marker approach.
