Modalita' di verifica dell'apprendimento: 

Assessment method
Oral exam with written parts. The written parts are part of the oral exam during which the students have to demonstrate the capability to mange the most important chemical equilibrium equations concerning the chemistry of the sea or they have to write the most important equations concernig the Alkalinity or draw the vertical profile behaviour of the most important chemical components od seawater in different oceans.

Obiettivi formativi

Aims
The course aims to provide students with knowledge about the processes and mechanisms that regulate the chemical composition of the sea and oceans. A special attention is given to climate change impact on the chemistry of the Oceans.

Contenuti

Contents
The course CHEMISTRY OF MARINE ENVIRONMENT provides an understanding of the chemical composition of seawater and related chemical reactions. Equlibrium and steady state conditions in aqueous solution are discussed. A particular attention is also given to priority and emerging pollutants.

Programma esteso

Detailed program
Properties of Water. Isotopes in seawater. Salinity and major constituents of seawater. Air-sea exchange of gases. Equilibrium and steady state models. Acid-base reactions. pH, chemical composition, buffer intensity in the oceans. CO2,HCO3-, CO32- equilibria in oceans and seawater. Log C – pH diagrams. Acidity and alkalinity. Concept of ocean acidification. Solubility, solubility-pH . Trace metals; metal ions speciation. Organic matter in the sea. Nutrients. Microplastics. Organic pollutants (i.e. hydrocarbons, pesticides, dioxins and PCBs, flame retardants, and endocrine substances). Atmospheric-ocean interaction: marine aerosols and their photochemistry and atmospheric aerosol as a source of nutrients. Geo-engineerng climate and the oceans.
