Voto Finale

The Environmental Analytical Chemistry course will provide the student an integrated approach to the principles and evaluation of modern analytical chemical methods. This approach will be focused on all environmental, as well as natural, compartments.
At the end of the course, the student will become familiar with :
- the theoretical and practical aspects of the modern instrumental analysis in the environmental field, as well as the statistical approach to data analysis.
- the choice and the application of such methods to sampling and analysis of solid and liquid samples.
- the critical evaluation of the obtained analytical data, as well as its statistical treatments, towards a multidisciplinary approach, particularly for toxicological and mineralogical aspects, to the multifaceted view of the environment in its widest context.

The student will learn the theoretical basis and the applications of modern instrumental analytical techniques.
Particular emphasis will be given to the application of these techniques to the environmental analysis.
