Example report

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.
• Understand how the Health Safety and Environment (HSE) regime is practiced at the Group of Environmental Analysis
