TOSSICOLOGIA AMBIENTALE E OCCUPAZIONALE CON ELEMENTI DI DIRITTO AMBIENTALE MOD. 1: TOSSICOLOGIA AMBIENTALE E OCCUPAZIONALE
Knowledge in the fields of Environmental and Occupational Hygiene, General Biology, Physics, Inorganic and Organic Chemistry, Environmental Chemistry are recommended. Knowledge of both spoken and written English is very useful.
Study of man-environment interactions, in terms of effects of human activities and anthropogenic pressures on environmental systems and also in terms of potential effects of the contamination of life and work environments on human health (toxicological risk). Particular emphasis will be given to effects and arising from exposure to contaminants (xenobiotics, endocrine disruptors, atmospheric particulate), to their mechanisms of action, to the environmental pressure on biological systems in vivo and in vitro (DNA and protein damage, cell damage, reproductive abnormalities , developmental alterations, teratogenesis and other biomarkers). The genetic, epigenetic and molecular mechanisms that regulate cell cycle and metabolic functions.
At the end of the course the student is expected to have acquired enough knowledge to correctly assess the toxicological risk from environmental pollutants in order to protect the health of populations in contaminated environments, to participate in impact assessment studies, to manage critical environmental issues and to communicate with professionals and people about toxicological risk in the most effective way.
Overview of background in anatomy, physiology and biochemistry. Overview of general concepts in Toxicology: absorption, distribution, metabolism and elimination of toxic substances (2 hours).
