Contents Survey of general chemistry. Astrochemical origin of atoms, nucleosinthesis and the Earth's atmosphere. Composition and chemical and physical properties of the Earth's atmosphere. Chemical cycles, transport models. Troposphere and anthropization. Air and water quality control, inventory. Modelling of the atmoshperes.
Reference texts Lecture notes. Suggested textbook: Colin Baerd, Michael Cann "Chimica Ambientale", Zanichelli.
Educational objectives After a survey of basic knowledge of general chemistry, students will acquire a background knowledge of atmospheric chemistry.
Prerequisites Background of General Chemistry
Teaching methods Face-to-face lessons. Students will witness performing of chemical analysis at the Departmental Environmental Chemistry lab.
Other information Period: October 2022-January 2023.
Place: Dipartimento di Chimica, Biologie e Biotecnologie. Address: Via Elce di Sotto 8
Learning verification modality Oral examination:

two separate exams for each of the two modules of the course.

- Objectives of the oral exam: the test aims to evaluate the specific knowledge of the student, in relation to the main topics considered during the lessons.
In particular, the student will have to demonstrate that he / she possesses the basic knowledge of general chemistry, applied to environmental problems; knowledge of the main processes and pollutants; knowledge of current legislation on environmental surveillance; main environmental analytical techniques considered in the practical lessons.

- Average duration of the oral exam: about 40 minutes for each of the two modules

Evaluation: final grade out of 30 obtained from the arithmetic average of the marks obtained for each of the two modules
