Environmental Biogeochemistry

This class will provide an overview of the essential concepts in biogeochemistry with an emphasis of processes occurring at the molecular level. This course introduces the important aspects of environmental biogeochemistry: sources, transport, reactions, effects, and fates of chemicals in the environmental compartments. It also focuses on the factors that influence biogeochemical cycles of key elements such as carbon, nitrogen and phosphorous but also of organic and metallic micro pollutants. The importance to take into account biogeochemical cycles when developing prevention strategies against hydrosystems pollution (artificial wetland buffer zone) and waste valorization bioprocesses will be emphasized through real cases study and field visits.

Course outline

• Molecular biogeochemistry in the natural environment

- Interplay between the molecular constituents of living organisms and the biogeochemical processes occurring in the environment

- How natural and anthropogenic activities impact the molecular transformations of elements like carbon, nitrogen, and sulfur in various environmental domains, such as soil, water, and air

- Sedimentary archives for paleo-reconstructions

• Molecular biogeochemistry in the anthropogenic environments

- Sources and fate of environmental pollutants

- The importance of biogeochemical cycles in hydrosystem pollution prevention strategies

- The importance of biogeochemical cycles in waste valorization bioprocesses

The module includes 18 h of courses and 16 h of practical work and a 4 h visit. 2 h written exam.
