Applied Analytical and Environmental Chemistry (environmental analytical chemistry)
Knowledge of general, inorganic and organic chemistry.
Aim of this course consists of the development of the following skills: 1) analysis and management of environmental problems derived from chemical pollution 2) application of these knowledges in a multidisciplinary context, taking into account also the legislation REACH 3) formulation of a judgment based on the available information 4) results reporting and drawing conclusions.
Introduction to Environmental Chemistry: main problems from chemical pollution. Interactions amnog the environmental compartments: air, water, soil. The REACH legislation.
Water medium: Physico-.chemical properties of aquatic compartment. The system CO2/H2O. Parameters for the water quality: solids, turbidity, BOD e COD, hardness, pH, alcalinity, ecc.) Complexation with synthetic complexant (phosphates, EDTA, ecc) and natural (humic acids). Soap and Surfactants. Ionic-Exchange resins.
Soil and sediment media: Geosphere. Different kind of Soil : inorganic (Clays) and organic. The sediments characteristics. Parameters for adsorption and environmental partitioning (Kd, Koc, Kow, Henry). Fertilizers and nutrients.
Principal organic and inorganic pollutants: Organic pollutants natural and anthropogenic: Aromatic hydrocarbons, Policyclic Aromatic Hydrocarbons PAH), PoliCloroBiphenyls (PCB), dioxins and furans, pesticides (various classes of insetticides, herbicides, fungicides), metals and organometallic compounds.
Biodegradations and photodegradations: main biotrasformation reactions by microorganisms. Main photochemical degradative reactions.
Air medium: structure and composition of atmospere. Main pollutant gases: CO, CO2, SO2, NOx. Green-house effect. Acidic Rains. Stratospeheric Ozone depletion (CFC and substituents) Photochemical Smog. Tropospeheric reactivity with OH e NO3 radicals and with Ozono. Atmospheric Particulate Matter (PM).
Introduction to QSAR Modeling: main predictive applications to organic environmental pollutants.
