Detail of lecture’s hours: 
Lesson (32 hours), Exercise (32 hours)
Requirements: 

Basic knowledge of environmental and analytical chemistry

Final Examination: 
Orale

Oral exam based on two sections:
1- Propose an analytical approach for the analysis of a specific group of analytes or for a specific environmental problem through an oral presentation (or with slides).
2- three short questions on specific sampling and analysis techniques for environmental samples.

The two sections have the same weight for the final evaluation.
The first section will evaluate both absolute knowledge and scientific rigor in the presentation of the theoretical bases. The second section will evaluate the ability to organize a rigorous analytical protocol and the originality of the proposal itself.

Voto Finale

TRAINING OBJECTIVES
The aim of the course is to present the main techniques for environmental sampling and analysis for different environmental matrices.
The course is divided into a theoretical parts in which will be presented: the principal techniques for sampling of different environmental matrices; the most used pre-treatments and analyses of environmental samples; the problems related with the choice of the best analytical protocols.
The second part of the course will include exercises aiming to prepare and perform a protocol of environmental sampling and analysis, including: sampling scheme setup; material preparation; the performance of a sampling campaign; sample pre-treatment and their laboratory analysis.

EXPECTED LEARNING RESULTS
At the end of the course, the student will be able to understand the application possibilities of the different analysis techniques presented also in real case studies, discussing the possible alternatives and complementarity between the information from techniques in order to propose a rigorous and complete analytical protocol.

The course aims to offer an overview of the main analytical techniques used in environmental analytical chemistry. The theory section will be divided in three phases (sampling, analysis and data treatment), and in detail will deal with:
1. The most common sampling strategies, treatments and conservation techniques of environmental samples, with a focus on the different environmental compartments and physicochemical properties of the target compounds;
2. The principal techniques of chemical analysis for samples obtained from different environmental compartments;
3. Basics of environmental data treatment, and result communication in different contexts.
The exercises will include the presentation of different case studies and the setup of a specific analytical protocol:
1. Presentation of some practical examples of sampling protocol setups, showing case studies present in literature;
2. Planning, material preparation and development of a sampling campaign;
3. Analysis of samples obtained from different environmental compartments and preparation of a sampling and analysis report.
