Environmental chemistry involves the study of the effects that chemicals have on the air, water and soil and how they impact the environment and human health. The aim of this course is to provide the basic skills to understand the chemistry of the environment, to give the student the tools that allow him to understand the environmental compartments, their interactions and the chemical and physical characteristics of the three matrices, water, air and soil. During the course attention will be paid to the main pollutants and contaminants, to environmental transport processes, their behavior and their distribution. The course helps to train professionals with multidisciplinary skills capable of intervene in the prevention, diagnosis and operational solution of environmental problems. During the laboratory exercises, some analytical techniques useful for monitoring pollutants will be illustrated. At the end of the laboratory, laboratory reports must be prepared by the students.

At the end of the course, students will be able to identify, analyze and evaluate the characteristics of the main environmental compartments, the processes that regulate them and their interactions. The student will be able to recognize the main classes of pollutants, the processes that generate them and their distribution in the environment. Furthermore, the student will have acquired the skills necessary to recognize natural environmental conditions distinguishing them from those altered by pollution phenomena. The student will have acquired knowledge that will allow him to formulate hypotheses suitable for the control, management and remediation of the environment. Furthermore The student will acquire the ability to communicate orally and in writing, with linguistic properties, the fundamental aspects relating to processes in environmental matrices.

Attendance of the course requires basic knowledge of general chemistry and physics. In particular: the units of measure, the nomenclature, the periodic table and its properties, the intra and intermolecular forces, phase transitions, the solutions and the properties of the solutions, the gas laws, the heterogeneous equilibria, the pH and acid-base equilibria, solubility, and precipitation equilibria, kinetics, thermodynamics, redox reactions and electrochemistry.

The course is organized in 4 modules (45h lectures and 15 laboratory and practical activity): 1) Introduction to organic chemistry, hydrocarbons, functional groups and classes of organic compounds (1 ECTS ING-IND/25). 2) Introduction to environmental chemistry, environmental compartments, pollution and toxicology. Distribution and fate of pollutants, transport, accumulation and degradation processes (1,5 ECTS ING-IND/25). 3) Atmosphere. Atmospheric pollution. Hydrosphere. Water pollution. Geosphere. Soil pollution. Interface interactions (1,5 ECTS ING-IND/25). 4) Main pollutant monitoring techniques, sampling, analysis, identification and quantification (2 ECTS, ICAR03 ).

The course is structured in: - 45 hours of lectures, aimed at developing knowledge relating to the main chemical species of environmental importance, their properties, their role in the natural and anthropic context, as well as the main pollutant monitoring techniques (as described in detail in the plan). - 15 hours of laboratory and pratical activities aimed at stimulating the ability to apply the acquired

... The exam is aimed at ascertaining the knowledge of the topics listed in the official program of the course, the student's ability to re-elaborate the notions acquired by also making connections between the different topics through the use of an appropriate language and the ability to express judgments in a autonomous. The exam will be oral and will take into account the laboratory report provided by the student at the end of the same. The final mark consists of 75% oral exam, and 25% laboratory report.

Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
