ENVIRONMENTAL CHEMISTRY - 2

The course contributes to shape graduates with multidisciplinary skills able to take action in the prevention, diagnosis and operational resolution of environmental problems, according to the general objectives of the Master Degree in Environmental Sciences.
in some detail, the objective of the course is to provide students with the necessary skills for understanding the dynamic (primary and secondary sources, transport, transformation and ultimate fate) of chemicals occurring in the environment. Special attention will be devoted to persistent, toxic and bioaccumulative substances and materials. Finally, the chemical aspects, strategies and technologies for the prevention and abatment of chemical pollution will be presented.

Knowledge and understanding
The student will acquire the knowledge and understanding of chemical and chemical-physical properties of main classes of environmental hazardous chemicals, chemodynamic, chemical aspects of environmental changes at local-to-global scales, prevention measures and abatement technologies. He will be instructed to carry out appropriate internet search.
Ability to apply knowledge and understanding
The student will acquire the ability to assess quantitatively the occurrence and behavior of chemical substances in the environment, and will benefit from wealth of information available on the Internet (worldwide web, www).
Autonomy of judgment
The student will acquire independent judgment on the evaluation of exposure to environmental chemicals by the integrated knowledge concerning their input, behavior and effects.
Communication skills
The student will acquire adequate skills e.g. appropriate terminology, for oral and written communication on the occurrence and behavior of environmental chemicals.

Fundamentals of chemistry, and environmental chemistry, provided by courses delivered in the first and third year of the Bachelor Degree in Environmental Sciences.

Geosphere and soil chemistry: chemical composition and physicochemical processes in soils: acid-base and ion exchange reactions; macro- and micro-nutrients and absorption and biodegradation processes of organic matter.
Atmosphere and chemistry of the atmosphere: energy and matter transfers, chemical composition and physicochemical processes in the atmosphere;
Chemical contaminants of the PBT (Persistent, Bioaccumulative, Toxic) type in air, waters and soil. Primary and secondary sources, and inventory of emissions. Physico-chemical properties of main classes of priority and emerging chemicals; general degradation pathways of aliphatic and polycyclic aromatic hydrocarbons, surfactants, and halogenated substances; speciation of metals and metalloids.
Chemodynamics in waters and air. Chemical potential, fugacity and partitioning of chemicals among environmental media. Bioaccumulation and overall redistribution of chemicals and hazardous materials.
Environmental chemistry of global changes: greenhouse effect; ocean acidification;
Prevention and treatment of pollutants in waters, soil and air; regulatory aspects. Removal of contaminants by physical and biological treatments of waters: potabilization; primary-secondary-tertiary treatments of municipal and industrial wastewaters; treatment and fate of chemicals in sludge from sewage treatment plants.
