One third of a century of anlytical sciencesin environmental research

During 33 years Walter Giger and his colleagues were active in research, teaching and con-

sulting 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 hydro-

carbons, 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 process-

oriented 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 assess-

ments 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.
