701-1341-00LWater Resources and Drinking Water
Findet dieses Semester nicht statt.
W3 KP2GS. Hug, M. Berg, F. Hammes, U. von Gunten
KurzbeschreibungThe course covers qualitative (chemistry and microbiology) and quantitative aspects of drinking water from the resource to the tap. Natural processes, anthropogenic pollution, legislation of groundwater and surface water and of drinking water as well as water treatment will be discussed for industrialized and developing countries.
LernzielThe goal of this lecture is to give an overview over the whole path of drinking water from the source to the tap and understand the involved physical, chemical and biological processes which determine the drinking water quality.
InhaltThe course covers qualitative (chemistry and microbiology) and quantitative aspects of drinking water from the resource to the tap. The various water resources, particularly groundwater and surface water, are discussed as part of the natural water cycle influenced by anthropogenic activities such as agriculture, industry, urban water systems. Furthermore legislation related to water resources and drinking water will be discussed. The lecture is focused on industrialized countries, but also addresses global water issues and problems in the developing world. Finally unit processes for drinking water treatment (filtration, adsorption, oxidation, disinfection etc.) will be presented and discussed.

701-1313-00LIsotopic and Organic Tracers in Biogeochemistry Information W3 KP2GC. Schubert, R. Kipfer
KurzbeschreibungThe course introduces the scientific concepts and typical applications of tracers in biogeochemistry. The course covers stable and radioactive isotopes, geochemical tracers and biomarkers and their application in biogeochemical processes as well as regional and global cycles. The course provides essential theoretical background for the lab course "Isotopic and Organic Tracers Laboratory".
LernzielThe course aims at understanding the fractionation of stable isotopes in biogeochemical processes. Students learn to know the origin and decay modes of relevant radiogenic isotopes. They discover the spectrum of possible geochemical tracers and biomarkers, their potential and limitations and get familiar with important applications
InhaltGeogenic and cosmogenic radionuclides (sources, decay chains);
stable isotopes in biogeochemistry (nataural abundance, fractionation);
geochemical tracers for processes such as erosion, productivity, redox fronts; biomarkers for specific microbial processes.
Skripthandouts will be provided for every chapter
LiteraturA list of relevant books and papers will be provided
Voraussetzungen / BesonderesStudents should have a basic knowledge of biogeochemical processes (BSc course on Biogeochemical processes in aquatic systems or equivalent)
701-1315-00LBiogeochemistry of Trace ElementsW3 KP2GA. Voegelin, M. Etique, L. Winkel
KurzbeschreibungThe course addresses the biogeochemical classification and behavior of trace elements, including key processes driving the cycling of important trace elements in aquatic and terrestrial environments and the coupling of abiotic and biotic transformation processes of trace elements. Examples of the role of trace elements in natural or engineered systems will be presented and discussed in the course.
LernzielThe students are familiar with the chemical characteristics, the environmental behavior and fate, and the biogeochemical reactivity of different groups of trace elements. They are able to apply their knowledge on the interaction of trace elements with geosphere components and on abiotic and biotic transformation processes of trace elements to discuss and evaluate the behavior and impact of trace elements in aquatic and terrestrial systems.
Inhalt(i) Definition, importance and biogeochemical classification of trace elements. (ii) Key biogeochemical processes controlling the cycling of different trace elements (base metals, redox-sensitive and chalcophile elements, volatile trace elements) in natural and engineered environments. (iii) Abiotic and biotic processes that determine the environmental fate and impact of selected trace elements.
SkriptSelected handouts (lecture notes, literature, exercises) will be distributed during the course.
Voraussetzungen / BesonderesStudents are expected to be familiar with the basic concepts of aquatic and soil chemistry covered in the respective classes at the bachelor level (soil mineralogy, soil organic matter, acid-base and redox reactions, complexation and sorption reactions, precipitation/dissolution reactions, thermodynamics, kinetics, carbonate buffer system).
This lecture is a prerequisite for attending the laboratory course "Trace elements laboratory".
701-1346-00LCarbon Mitigation Information W3 KP2GN. Gruber
KurzbeschreibungFuture climate change can only kept within reasonable bounds when CO2 emissions are drastically reduced. In this course, we will discuss a portfolio of options involving the alteration of natural carbon sinks and carbon sequestration. The course includes introductory lectures, presentations from guest speakers from industry and the public sector, and final presentations by the students.
LernzielThe goal of this course is to investigate, as a group, a particular set of carbon mitigation/sequestration options and to evaluate their potential, their cost, and their consequences.
InhaltFrom the large number of carbon sequestration/mitigation options, a few options will be selected and then investigated in detail by the students. The results of this research will then be presented to the other students, the involved faculty, and discussed in detail by the whole group.
SkriptNone
LiteraturWill be identified based on the chosen topic.
Voraussetzungen / BesonderesExam: No final exam. Pass/No-Pass is assigned based on the quality of the presentation and ensuing discussion.
