Objectives Contents Basic knowledge to characterise the main pollution issues related to water and soil matrices
Extended Syllabus Global pollution of environmental matrices; climate change impacts and adaptation; desertification; nitrate and fossil fuels related pollution. Atmosphere composition, residence times, dynamic and PBL. Main air pollutants: acid rains, O3, Nox, Sox, VOCs, particulate matter, asbestos and radon. Hydrosphere: oceanic and continental waters: major and trace elements, nutrients composition. N, O, cycles pollution by N, eutrophication, hydrocarbons and their properties DNAPL etc., POPs, COV, dioxins, heavy metals. Bacterial pollution. Soil: evolution, physio-chemical characteristics, main pollutants. Planning and execution of water sampling, in situ physio-chemical measures according to law standards. Spectrophotometric analysis of NH4, NO2, NO3, PO4, COD, Cl, SO4. BOD5 determination. TXRF analysis of trace metals in environmental matrices. Statistical data elaboration, classification and comparative diagramming.
Recommended Bibliography Geochimica e Ambiente (Dongarrà G. e Varrica D. edito da EdiSES s.r.l, 2004)ISBN: 8879592823
Teaching Methods Teaching will be with frontal lessons, fieldwork, traing in lab
Evaluation methods Verification of learning:
The verification of the alumn's learning is made through three writing tests during the semester. The aim is to verify the knowledge, understanding and appropriate use of technical language. The positive outcome of the test grants access to the final oral exam to test the logical path acquired necessary to face evironmental pollution issues.
Contacts/More Information The course aim is to provide basic knowledges of the geochemical mobility in and within air,water and soil and their interaction with the biosphere.The field and laboratory work will provide the practical skills for sampling and analysis of air, water and soil. The main physical and chemical and batteriological characterisation of water will be carried out by the students using different instruments. Geochemical data elaboration, interpretation finalisd to assessing law conformity and pollution potential source will complete the "hands on" training.
