In industrialisierten Ländern ist der Einsatz synthetischer Pharmaka für die Diagnose und Therapie von Krankheiten, für das Wohlbefinden der Bevölkerung und für die Fertilitätskontrolle zum festen Bestandteil des Alltags geworden. Der Verbleib dieser Teils hochwirksamen Stoffe nach ihrer Zweckanwendung sowie die Entsorgung ungebrauchter Produkte sind wichtige Fragen, die unmittelbar aus der Befürchtung möglicher Auswirkungen auf die Umwelt erwachsen. Unter dem Titel "Heillasten", der die ambivalente Rolle der Pharmaka widerspiegelt, will dieses Buch eine Standortbestimmung zu diesem aktuellen Problembereich vornehmen und Wege aufzeigen, wie man zukunftsgerichtet mit ihm umgeht. Dies geschieht transdisziplinär aus den Blickwinkeln der Entwicklung und Verwendung der Produkte, der Medizin, des rechtlichen Umweltschutzes, der Gewässerökologie und der Wassertechnik. Der angestoßene Diskurs auf der Basis belastbarer Fakten und fachkundiger Einschätzungen soll helfen, den aktuellen Informationsstand und weiteren Forschungsbedarf aufzuzeigen.

Colloids are known to be the often neglected phase for the transport of pollutants in aquatic ecosystems. The book covers the basics of abiotic colloid characterization, of biocolloids and biofilms, the resulting transport phenomena and their engineering aspects. The subject is presented from an international group of leading specialists devoted to colloidal sciences. The contributions include theoretical considerations, results from model experiments as well as field studies. The information given will serve students and scientists interested in the analytical, chemical, microbiological, geological and hydrological aspects of material transport in aquatic systems and soils.

As nanotechnology enters everyday life, engineered nanoparticles (ENP) will find their way into nature, including surface and groundwater. Here, distinguished experts of water chemistry present dedicated methods for the analysis of nanoparticles in the aquatic environment, their distribution and fate. This includes the influence of complex matrices such as wastewater, brown water with natural organic matter (NOM), and high salt concentrations as well as available and future standardized methods. The background of geogenic, natural nanoparticles is considered in a discussion of known environmental effects, including strategies to test for potential effects on human and environmental health.
