ENVIRONMENTAL INORGANIC CHEMISTRY
Learning outcomes of the course unit
Knowledge and understanding: the course aims to illustrate the fundamental principles required for the understanding and description of the chemical mechanisms determining the environmental impact of specific classes of natural and anthropic inorganic pollutants. Ability to learn: the course aims to provide the necessary chemical language required for reading and understanding basic and advanced texts on the subject. Ability to communicate: the student acquires the technical language needed to communicate with specialists and necessary to properly express complex concepts in an understandable language. Making judgments: by means of the acquired knowledge the student is able to critically develop an independent opinion on the possible environmental impacts produced by the phenomena and processes discussed in the course.
The knowledge of the basic concepts of general chemistry and organic chemistry is required.
Course contents summary
The first part of the course aims to provide the fundamental tools and information useful to understand the role played by the main anthropogenic pollutants on the chemistry of the atmosphere. The second part of the course provides general information regarding the spontaneous and non-spontaneous transformation processes of atomic nuclei and describes the methodologies and environmental problems related to the civil and military applications of nuclear energy. The third part is dedicated to the study of relevant chemical parameters able to rationalize the interaction mechanisms between metals and organic substrates.
