Learning requirements:

The student is expected to:

• Acquire experience of water sampling from various compartments through the watershed
• Understand the difference between total analysis, fractions and species
• Understand the concept of multiple simultaneous equilibriums
• Understand the basic principles of mobility and toxicity of chemical species
• Learn how to conduct an Al-fractionation and have experience from the analysis of major anions and cations
• Be able to run the MINEQL+ programme
• Relate to environmental monitoring data and to write a report where data are evaluated and interpreted.

Lecture, V205, hr. 08:15 ¨C 10:00

Difference between total analysis, fractionation and species , The significance of species activities rather than total concentration in terms of mobility and toxicityChemical analytical speciation and fractionation (Al) methods Water sampling from different compartments of the environmentSampling strategies for environmental samples

"Case study: Eutrophication in Vansj?", The Vansj?-Hob?l watercourse is suffering severe problems with eutrophication due to too high phosphorous levels despite significant abatement actions over the last 10 years. These abatement actions are based on Total P measurements. Perhaps it is more sound to get a grip on the sources and distribution of the P fractions that are - or may become - bioavailable..
