U-gov code ST03 3S336

Prerequisites

Knowledge of the topics of the courses on mathematic, physic, general, inorganic, organic and instrumental analytical chemistry

Development of the course

The course consists of theoretical lectures (4 credits, 32 hours) and laboratory practical work carried out individually or at small groups and fieldwork (2 credit, 16 hours). 

Learning outcomes

Knowledge. The course enables students to acquire the fundamental knowledge of the principal advanced analytical techniques for the analysis of pollutants in the environment (high pressure liquid chromatography HPLC, gas-chromatography GC, mass spectrometry MS, Inductively Coupled Plasma Mass Spectrometry ICP-MS), and the knowledge of the principal extraction methods for environmental analysis (Liquid-Liquid extraction, Solid Liquid Extraction) from the different matrices studied (air, water, soil) .The course enables students to acquire the fundamental knowledge on national and international legislations on limits and methods of analysis of environmental pollutants, too.

Ability to apply the knowledge:
The student should also acquire the following professional skills: ability to collect and analyse environmental samples on field, ability to extract the pollutants by collected matrices (MAE, LLE, ecc) and relative chromatographic analyses. Finally the student should acquire the capability to value the analytical data obtained according to law limits, provided by national and international institutions.

Soft skills:
The analyses of environmental samples contribute to improve for the student the degree of judgement autonomy in general, because the student will learn the capability to value the data obtained in line with the corresponding limits law, encouraging a discussion above. The communicative capacity will be stimulated during the lessons by discussing with the teacher some scientific report or papers (even in English language) on environmental monitoring anda pollutants analyses in different matrices. The execution of field and laboratory analyses contributes to improve for the student the degree of judgement autonomy in general, the communicative capacity (which derives also from the teamwork), the learning capacity in autonomy, and the ability to draw conclusions from experimental data.

Program

CContent (lectures, 4 CFU, 32 hours).
Sampling methods, sample preparation, treatment and storage. Extraction methods for environmental analysis: Liquid-Liquid extraction, Solid Phase Extraction (SPE), Solid Phase Micro-Extraction (SPME), Solid-Liquid Extraction, Soxhlet and Soxtec methods, Accelerated solvent extraction, Microwave extraction. Quality of analytical data: accuracy and precision, repeatability and reproducibility, detection limit, validation of analytical data. Application of instrumental analytical techniques for pollutant analysis. Chromatographic techniques: high pressure liquid chromatography (HPLC), gas-chromatography (GC); mass spectrometry (MS); coupling HPLC-MS and GC-MS; Inductively Coupled Plasma Mass Spectrometry ICP-MS. Pollutants analysis. Dangerous and priority pollutants. Emerging pollutants. National and international legislations on limits and methods of analysis of environmental pollutants

Development of the examination

Methods for assessing learning outcomes:
The examination is an oral exam: during the examination the teacher evaluates the student learning.

Criteria for assessing learning outcomes:
During the oral examination the student will be demonstrate to know the principal techniques of extraction and analysis of the pollutants, at least on three topics of the whole programme.

Criteria for measuring learning outcomes:
The final mark is attributed in thirtieths. Successful completion of the examination will lead to grades ranging from 18 to 30, and 30 with laud.

Criteria for conferring final mark:
The final mark is attributed by evaluating the learning of the student on the contents of the course and by evaluating the complete mastery of the matter.
