CHIMICA DELL'AMBIENTE E SENSORI PER IL MONITORAGGIO AMBIENTALE

Academic Year 2023/2024 - Teacher: GIUSEPPE FORTE

Expected Learning Outcomes


The aim of the course is to provide students with knowledge on the main sources of pollution in the various environmental matrices: air, water and soil; on the main pollutant monitoring techniques, on the main environmental sensors and their use in controlling the quality of the environment.
In this context, the student will acquire the following knowledge: 1) main sources of pollution, type of pollutants and concentration limits of pollutants in the various environmental compartments; 2) specificity and critical points of each environmental sector, 3) Hazardous waste; 4) main methods for a correct carrying out of sampling, storage, sample treatment and analytical determination; 5) main sensors for monitoring chemical and microbiological pollutants in environmental matrices; 6) interpretation of the analytical result for a correct evaluation of environmental monitoring; 7) Italian legislation on pollution and waste.

Water pollution. Chemistry and water pollution. Waters for civil, industrial and agro-zootechnical use. Main inorganic and organic pollutants in water, acidity and oxygen demand.
Soil pollution. Soil chemistry and pollution. Heavy metals and pesticides. Waste: nature, sources and classification of hazardous waste.
Principles of Statistics. Statistical treatment of data and main analytical parameters.
Sampling and analysis methods. Main methods of sampling and environmental chemical analysis. Monitoring of volatile organic substances (BTEX, IPA etc.), inorganic oxides (NOx, SOx) and heavy metals. Sampling and main analysis techniques of particulate matter (PM10 and PM 2.5) in the atmosphere. Sampling and main analysis techniques of asbestos fibers. Sampling of microplastics in water and main analysis techniques.
