Course Curriculum CFU Length(h)


- Knowledge and understanding: The laboratory aims to provide students with the knowledge required to identify and quantify the main contamination phoenomena occurring on enviromental matrices.
- Applying knowledge and understanding: The proposed activities within the Laboratory will allow the student to know and understand the steps required for an adequate characterization of a contamination phenomena, to familiarize with the equipments available in a chemical-environmental laboratory, to apply the analytical methods required for the quantification of main contaminants in solid or liquid phases .
- Making judgements: At the end of the course, the student will have acquired the capacity of elaborate and critically understand the obtained results
- Communication skills: At the end of the course, the student will have acquired a more deep knowledge of the parameters commonly used to characterize and quantify environmental pollution of water bodies or soils.
- Learning skill: at the end of the Lab the student will be able to continue studying in a self-directed or autonomous way.

Teaching Methods

Lessons will be held at the Environmental-Chemical Laboratory of DICAAR. After a preliminary introduction illustrating aims and scopes of the analytical protocol, students will execute the analytical method of interest under the supervision of the Professors and Researchers, following the safety procedures dictated within the laboratory activities.

Verification of learning

Students must to prepare a written report concerning the activity carried out during the classes, that will undergo to a revision in order to provide the expected credits.
