CHEMISTRY OF MARINE ENVIRONMENT
Basics of inorganic and organic chemistry.
Oral exam with written parts.
The course aims to provide students with knowledge about the processes and mechanisms that regulate the chemical composition of the sea and oceans.
The course CHEMISTRY OF MARINE ENVIRONMENT provides an understanding of the chemical composition of seawater. Equlibrium and steady state conditions in aqueous solution are discussed. A particular attention is given to priority pollutants.
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 seas and oceans: CO2,HCO3-, CO32- equilibria in oceans and seawater. Log C – pH diagrams. Acidity and alkalinity. Concept of ocean acidification. Solubility, solubility-pH diagrams. Trace metals; metal ions speciation. Redox reactions in seawater. 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.
