Objectives
1. week: Introduction and detailed description of the subject's objectives, some thoughts on the causes of environmental pollution.
Development and the present composition of the atmosphere and hydrosphere. Dobson unit, formation of hydroxyl radicals.
2 week: The main groups causing pollution: airborn and waterborn pollutants
Airborn pollutants: carbon dioxide, nitrogen oxides, sulfur oxides, hydrocarbons, halogenated hydrocarbons, dioxines and photochemical oxidants, particulates.
Chemical properties and ways of formation and/or elimination of environmental polluting materials, the reaction kinetics, and control methods of these processes will be discussed in the following lectures as well.
The natural and anthropogenic sources of carbon monoxide. Formation of CO from methane and elimination from the atmosphere. Technological possibilities to reduce emission.
3. week: The origin and kinetic of the formation of nitrogen oxides, NOx (NO, NO2, N2O and short live forms), the photocycle of nitrogen-dioxide, ozone formation in the lower atmosphere. The effects on plants, animals, humans and on structural materials
4. week: Sulfur oxides originated naturally and from human activities. The kinetic of the formation of different SOx. The chemical effects of acidic rains. The technological possibility of decreasing SO2 formation.
5. weeks: hydrocarbons and photochemical oxidants. London type and photochemical smog.
Hydrocarbon decreasing technologies.
6. weeks: Formation of halohydrocarbons , Ozone –hole, , Dioxins (TEF, TEQ), Dioxin decreasising technologies.
7. weeks: Particles, aerosols, smog, fog. Chemical composition and size distribution of particles. The effects of particles on the living systems. Meterological aspects of air-pollutants.
Particle elimination technics.
8. weeks: Global warming, greenhouse effect, possible causes of periodical climate changes.
9. weeks: Future and energy , Bioenergy, biodiesel, bioethanol,
10. weeks: Waterborn pollutants: organic materials, toxic organic materials, plant nutrients, mineral oil and fractions, detergents, pesticides and toxic metals.
High oxygen demand wastewater, aerob and anaerob fermentation
11. weeks: High oxygen demand and toxic wastewater. Oil spills, environmental effects, decontamination technologies
12. weeks: Plant nutrient-containing wastewater,
13. weeks: Detergent-containing wastewaters, the properties and types of detergents, their
environmental effects.
14. weeks: Pesticides, groups of pesticides, DDT, the new, third generation pesticides
