The Giger Group 1972– 2005 - Novaquatis
Environmental Research The Giger Group 1972– 2005 Symposium: Analytical Sciences in Environmental and Geological Research Tuesday, 20 September 2005 Group members and publications Eawag: Swiss Federal Institute of Aquatic Science and Technology One third of a century of anlytical sciences in environmental research During 33 years Walter Giger and his colleagues were active in research, teaching and consulting in the field of trace analysis of organic pollutants in technical and natural systems. The Giger group, has contributed substantially to increase our knowledge on the occurrence of organic micropollutants and on their environmental fate and behaviour. Over the years, they studied many classic and emerging contaminants among them petroleum hydrocarbons, polycyclic aromatic hydrocarbons, polychlorinated solvents, detergent chemicals (e.g. surfactants, phosphate substitutes, complexing agents, optical brighteners), toxic and estrogenic nonylphenols, concrete admixtures, antibiotics, flame retardants, corrosion inhibitors and biocides. Forefront trace analytical methods were developed for processoriented field studies, which were performed mainly in wastewater treatment and in natural waters (rivers and lakes) but also in rain, fog, drinking water, lake sediments and sewage sludges. An important objective was to provide information for environmental risk assessments and to propose mitigation measures to reduce the inputs of pollutants into the aquatic environment. Based on the obtained research results, legal regulations and voluntary actions were proposed aiming at the reduction of the residual levels in the environment.
