Geochemistry

The training of the students in the geochemical processes,  which are taking place in the hydrosphere ,lithosphere  and biosphere,. In the laws  which control the translocation and movement of the elements from one part  of land to another, and their  significant effects on   the  climate and humans. Also, the students will be prepared to understand the genesis  of rocks  ,soils and sediments

The students posses the intellectual  capacity and practical skills and has the ability:

• To apply the knowledge and   constructive thinking in the solution of the geochemical problems, in   decision   making in relation to critical technical  selection on crucial  subjects,   and in  management of specific environmental areas
•      Also the student in the  working environment  has the  ability to respond:
• With sufficiency in the  interscientific   knowledge required for the solution of the geochemical problems
• With responsibility  and trustworthiness in the  case of autonomous working in the  professional sector

• Reach, analysis and synthesis of data with the use of  the  required  modern technologies
• Decision making
• Adjustment to new situations
• Working in  interscientific  environment

• Basic geochemical principles and processes, lithosphere, hydrosphere,biosphere,atmosphere.
• Physical characteristics of sediments and their importance in the  geochemical processes
• Chemical characteristics of sediments. Elements  and  geochemical phases as indices    of  sediment  genesis environment.
• Chemical characteristics of rocks
• Geochemical processes
• Processes of chemical weathering
• Processes of chemical diagenesis
• Soils and sediments
• The geochemistry of heavy metals
• Sources of heavy metals ( natural and anthropogenic)
• Behavior of heavy metals in soils and water( release, adsorption/desorption, fixation, immobilization, ion exchange, volatilization).
• Factors affecting adsorption and desorption of heavy metals
• The bioavailability of heavy metals
• Relation of heavy metals to the biotic systems  of the environment  (plants, humans, animals)
• Sea geochemistry: Chemical composition of the sea water, equilibrium of the  soluble components of sea water. Sources of entrance of  water  components in the sea environment. Water  Characteristic layers of the water  column. Geographical and perpendicular changes  of trace element in the water  column. Suspended matter, Geographic and perpendicular distributions. Composition of the  suspended matter Benthic layer. Resuspension of the sediments Sea sediments,  Composition, categories, sources, origin of the components. Hydrothermic  activity,Hydrothermic  metalliferous sediments.
• Biogeochemistry: Biogeochemical processes in the water systems.. Importance of the dissolved oxygen. Organic matter.  Carbon  Formation and decomposition of the organic matter.. Biogenic elements and their significance  in the evaluation of  the environmental conditions.. Trace elements  cycles., , mineral carbon, characteristic elements.
• Special extreme environments: The importance of knowledge of the  geochemical processes in  the management of extreme environments. Black  Sea, Lagoons ,Persian golf, Red sea, Undersea hydrothermic areas
• Environmental pollution

• e-teaching of the lab exercises on weakly basis  two (2) days before the  teaching process, personally to each student after his registration in the web page of  the Laboratory
• Support of learning process and diffusion  of the  trainer via the electronic platform  e  class

I)Assessment of the  lab  exercise

• Each exercise is reported completely solved, is corrected and graded
• The mean vakue of all the exercises  is calculated

II) Final written exam of the Coarse

• Eight out of 10 questions must   are synoptically responded, and among them  two lab  questions are included.
