Environmental Analytical Chemistry
A.Y. 2020/2021
Learning objectives
The aim of the course is to provide advanced knowledge in the field of analytical chemistry applied to the characterization of environmental matrices such as air, water, soil and food.
Expected learning outcomes
At the end of the learning process the student will acquire skills related to the use of advanced analytical methodologies for the characterization of air, water, soil and food for the purpose of identifying pollutants also present at trace level. Furthermore, the student will be able to plan an analytical protocol concerning all the analytical steps starting from sampling up to the analysis and evaluation of the error associated with the different procedures.

Course syllabus
Sampling methods, preparation, treatment and conservation of environmental samples (air, water, soil, food). Dissolution, digestion, extraction, concentration: main traditional and innovative methodologies. Quality and validation of the analytical data. Notes on the use of chemometric methods for the treatment of environmental data.
Innovative applications of the following techniques: elementary analysis techniques (AAS, ICP-OES, ICP-MS, XRF) for the determination of traces and ultratraces species; chromatographic techniques (GC-MS, LC-MS) and target and un-target applications; thermo-optical methods (TOT, TOR); coupled techniques (LC / ICP-MS; MS-MS; TGA / FT-IR); spectroscopic techniques and electron microscopy techniques.
Applications of analytical techniques for the analysis of the main environmental pollutants in water, soil, air, atmospheric particulate and food. Among the main pollutants will be mentioned: metals and organic species containing metals, pesticides, polycyclic aromatic hydrocarbons, polychlorinated biphenyls and dioxins, emerging organic pollutants. Outline of applications in the field of forensic analytical chemistry. Applications of innovative analytical methodologies for the characterization of cultural heritage and for the study of degradation induced by pollution on cultural heritage.

Teaching methods
Metodi di campionamento, preparazione, trattamento e conservazione del campione ambientale (aria, acqua, suolo, food). Dissoluzione, digestione, estrazione, concentrazione: principali metodologie tradizionali e innovative. Qualità e validazione del dato analitico. Cenni all'impiego di metodi chemiometrici per il trattamento dei dati ambientali.
Applicazioni innovative delle seguenti tecniche: tecniche di analisi elementare (AAS, ICP-OES, ICP-MS, XRF) per la determinazione di tracce ed ultratracce; tecniche cromatografiche (GC-MS, LC-MS) ed applicazioni target e un-target; metodi termo-ottici (TOT, TOR); tecniche accoppiate (LC/ICP-MS; MS-MS; TGA/FT-IR); tecniche spettroscopiche e tecniche di microscopia elettronica.
Applicazioni di tecniche analitiche per l´analisi de principali inquinanti ambientali presenti nelle matrici acqua, suolo, aria, particolato atmosferico e food. Tra i principali inquinanti verranno menzionati: metalli e specie organiche contenenti il metallo, prodotti fitosanitari, idrocarburi policiclici aromatici, policlorobifenili e diossine, inquinanti organici emergenti. Cenni ad applicazioni nel campo della chimica analitica forense. Applicazioni di metodologie analitiche innovative per la caratterizzazione dei beni culturali e per lo studio del degrado indotto dall'inquinamento sul patrimonio culturale.
