Course description

Introduction to environmental chemistry. Chemical physical properties of the water molecule; structure of water molecule, ipolimnio, thermoclinio, epilimnio. Stratification of waters, density as function of salinity, temperature and pressure. Dissolved oxsigen in waters ,Oxygen Demand: biological and chemical decomposition of organic matter in water. Sulfur compounds in natural waters, acid mine drainage. pE scale. pE-pH diagram of Fe and of N.CO2 dissolved in waters. CO2-carbonate system. Water in equilibrium with solid calcium carbonate: first and second approximation. Water in equilibrium with both CaCO3 and atmospheric CO2. Chemical composition of natural water. Alkaline index. Hardness index. Composition of the Major Components of Seawater: The Concept of Salinity, Clorinity. Composition and Stoichiometry of Average Seawater. Causes of the Major Components Not Being Conservative: examples (estuaries, anoxic basin, evaporation in isolated basin, admixture with brines, precipitation and dissolution, submarine vulcanism, vent, interstitial waters, exchange between atmosphere and sea). Phosphate, soaps. Nitrate, perchlorate, organic solvent in water.

 

Introduction to the atmosphere. Stratification of the atmosphere. Stratosferic chemistry: the ozone layer. Absorption of light by molecules. Creation of ozone in the stratosphere. Destruction of stratospheric ozone. Catalitic processes of ozone destruction. The ozone holes. CFC. CFC replacement.

The chemistry of ground level air pollution. The chemical fate of trace gases in air.. Urban ozone: the photochemical smog process Nitrogen oxide. Sulfur dioxide and hydrogen sulfide sources and abatement. Particulate air pollution.

Introduction to soil. Minerals. Cation and anion exchange.

Organic molecula of environmental interest. Pesticides. Dioxine. PAH. Furan.

Determination of ammonia in water sample. Determination of major ions in water sample. Determination of heavy metals in water sample.
