| Module: MODULE A - CHEMICAL MONITORING
(objectives)
MODULO A inglese
The course introduces and deepens the concepts and main experimental approaches on the chemical aspects of environmental monitoring through the knowledge and practice of the main instrumental methods for the qualitative and quantitative chemical analysis of organic and inorganic substances present in the environment. Knowledge will focus in particular on chemical monitoring of water and soil.
A) Educational objectives: To build a theoretical and applicative competence on the chemical aspects of environmental monitoring.
B) Expected learning results:
1) Knowledge and understanding: the knowledge will concern in particular the chemical monitoring of superficial water and soil;
2) Knowledge and comprehension skills applied: part of the course will be dedicated to carrying out practical exercises from an applicative applicative point of view, simulating real situations;
3) Autonomy of judgment: knowledge and practical application will allow autonomy of judgment and planning skills;
4) Communication skills: knowledge and application practice will also be useful in the development of communication skills through the reading and interpretation of the instrumental data obtained;
5) Ability to learn: the ability to learn will be evaluated through exercises concerning theory and interpretation of instrumental data.

(syllabus)
Data Quality: Principal parameters for the validation of an analytical method: detection and quantification limits, sensibility, robustness, recovery and use of certified materials; analytic approximation referred to law limits and interpretation of experimental data; expression of analytical results; systematic and random contribution to the approximation. (DM 260/2010, allegato 1, Pag 29-30).
Sampling and sample preparation: sampling representativeness considering the adopted sampling technique; sample storage; compatibility of the sample with the instrumental techniques; sample pretreatment: liquid-liquid and liquid-solid extraction; sample purification.
Principles of Organic-Analytical Chemistry: mixtures separation: crystallization, solvent extraction: extraction with supercritical fluids, distillation, chromatography. Chromatography: theoretical considerations, partition coefficient, resolution. Chromatographic techniques: adsorption, partition, ionic exchange, exclusion. Chromatographic methods: Thin Layer Chromatography (TLC), Gas chromatography (GC-MS), High Performance Liquid Chromatography (HPLC). Spectroscopy: the electromagnetic spectrum, radiation-matter interaction, effect of the chemical structure on the absorption, Lambert-Beer law. Principal environmental applications of the atomic and molecular spectroscopy: flame and graphite atomizers for the atomic absorption; plasma spectroscopy, Inductively Coupled Plasma-Mass Spectrometry (ICP-MS); Ultraviolet-Visible (UV-Vis) spectrophotometry, infrared (IR). Calibration Methods: external calibration, use of an internal standard, adding method. Nuclear magnetic resonance (NMR) spectroscopy.
Environmental chemistry:
water: alkalinity and acidity, oxidation, reduction, complexation and chelation reactions.
Organic and Inorganic pollutants:
organics: Polycyclic aromatic hydrocarbon; polymers; oils and lubricants. Polychlorobiphenyls and derivatives (polychlorobiphenyls, furans e dioxins). Surfactants: persistence, solubility, transport and hydrolytic reactivity.
inorganics: N-NH4, N-NO3, total Phosphorus and dissolved Oxygen (LIMeco descriptors).
Laboratory: liquid-liquid extraction, spectrophotometric analysis of N-NH4, total Phosphorus and dissolved Oxygen, GC-MS and NMR analyses of the organic pollutants (Analytical Methods Acque-APAT, IRSA).

| Module: MODULE B - BIOLOGICAL MONITORING
(objectives)
MODULO B inglese
Understanding the meaning of the use of biological indicators for environmental monitoring. Acquisition of general skills for the use of the biological methodologies provided for by the laws in force on environmental monitoring, in particular that of aquatic systems, through the integral application of a biological index.
A) Educational objectives: to develop design and execution skills for biological monitoring according to the principles and methods contained in current European and Italian legislation.
B) Expected learning results:
1) Knowledge and understanding: The acquired knowledge will concern the general principles on which biological monitoring activities are based, the methodological processes for the implementation of monitoring campaigns, and the determination of biological indices of environmental quality.
2) Knowledge and comprehension skills applied: The application of knowledge will be focused on a methodological study of the indexes currently used to assess the ecological status of environmental matrices, considering in particular soil and inner watercourses, through practical activities in the field and in the laboratory.
3) Autonomy of judgment: The ability to formulate independent assessments can be exercised in the interpretation phase of the results, coordinating the heterogeneous data to arrive at motivated judgments.
4) Communication skills: These skills will be developed through the exercise of one's own expression (interventions during the lessons) and in the coordination of group activities.
5) Ability to learn: The methodological study can allow the extension of the concepts and practices to the monitoring application to other environmental matrices.
