Module general description:
The soil environment as waste receiver
The Earth and its inhabitants. Creation of planet Earth. Energy and material cycles in Earth. Man on Earth. Modern society and the future. The soil environment as waste receiver. The hydrological cycle. The movement of water on the surface and underground. Groundwater quality. Soil and underground pollution. The land as waste receiver. Geoenvironmental criteria for landfill siting. Land habitats and biosocieties. The environment that sustains life. Land ecosystems. Natural ecosystems in Greece. Agricultural ecosystems in Greece.

The marine environment as waste receiver
The anaglyph of oceans. Sediments in oceans. The natural behaviour of sea water in the oceans. Ocean resources. Sea reserves and biosocieties. Natural processes in the marine environment. Biogeochemical processes in the marine environment. Dispersion mechanisms of pollutants in the marine environment. Mathematical models for pollutant transport and dispersion.

The atmosphere as waste receiver
Meteorology and dispersion of air pollutants in the atmosphere. The atmosphere: composition and physical characteristics. Chemistry of the atmosphere – troposphere and air pollutants. The behaviour of particles in the atmosphere.

Waste disposal and environmental impact
Impacts of gaseous emissions on the environment. Ozone depletion. The greenhouse effect. Sea-level rising. Desertification. Acid rain. Impacts on living organisms. Impacts of wastes on land. Mechanisms of entry and pollution indicators.Surface water pollution. Soil pollution. Aquifer pollution. Impacts on biosocieties. Impacts on public health. Protection measures. Waste disposal on land. The marine environment as waste receiver. Marine pollution and pollutants. Pollutant classification. Sources of marine pollution. Transboundary transport of atmospheric pollution. Impact assessment studies. Large industrial systems. Risk assessment studies.

Learning Outcomes: At the end of the thematic unit DIA 50 the students will achieve a good understanding of,
-the physical chemical , biological and geological processes occurring  on land in the aquatic and atmospheric environment in relation to the presence of pollutants.
- the assessment of the quality of the environment
-  the environmental impact of the waste .
At the end of the thematic unit DIA 50 the students will have the ability  to,
- write scientific papers
- apply the knowledge in assessing the environmental quality
- understand the environmental problems
- to apply methodologies in decontaminating the physical environment.

Subjects covered:
1. The terrestrial environment as waste recipient
2. The marine environment as waste recipient
3. The atmosphere as waste recipient
4. Waste disposal and its impacts on the environment

Learning Material: The HOU publications can be viewed

Teaching Method: Distance education with five Contact Sessions held at weekends during the academic year

Evaluation: Completion of five written assignments during the academic year, the average grade of which constitute a 30 percent of each student's grade, if a pass is obtained in the final or repetitive examination. Final exam grades constitute a 70 percent of the students' final course grade. More information is available
