Content

1. Basic chemical knowledge on atmospheric pollutants (Sources, reactions, effects)

2. Water - unique medium for solution-state processes, reactions and substance transportation

3.+ 4. Chemical aspects of weathering

- Silicate weathering (re-formation of minerals, ion exchange, soil acidification)

- Karst formation (carbonic acid equilibrium, water hardness, dripstones, e.g.)

- Pyrite weathering (example: rehabilitation of open-cast lignite mining sites)

- Corrosion (acid, oxygen, hydrogen, sulfide, and chloride corrosion)

5. Fertilizer chemistry (long-lasting fertilizers, nitrification inhibitors, eutrophication, e.g.)

inorganic pollutatnts

6. Construction chemistry (types of mortar, stones, cement, concrete formation and corrosion)

7.+ 8. Organic Chemistry - (Fundamentals of organic chemistry, organic substance groups - a brief survey, synthesis, properties, utilization and typical reactions of selected substance groups)

9. Synthetic polymers (general overview, linking principles, examples from the fields of environmental engineering, water management and civil engineering, ageing of polymers)

10. "Renewable" biopolymers (basic structural aspects, properties, utilization)

11. Terrestrial and aquatic humic substances (structur, formation, functions, analysis).

Methane hydrate - boon or bane for next generations?)

12. Ubiquitary organic pollutants

- Sum parameters (PAH, PCB, MKW, LHKW, HFCs, DOC, TON, BTX, AOX, EOX, POX, COD, BOD5 ...what´s

behind all this? - sources, toxicological facts, analysis)

- TCDDs, TCDFs and Ames mutagenic compounds (formation, toxicological facts, analysis)

- Endocrinic substances (phthalates, tin-organic compounds, nonyl and octyl phenols, PCP;

sources, toxicological facts, analysis)

13. Pesticides in agriculture and forestry (Insecticides, Herbicides, Fungicides - chemistry of

selected substance classes, application rates, persistency

14. Buffer, recapitulatio

Previous knowledge expected


Objective (expected results of study and acquired competences)

The main objective of the lecture is to impart a comprehensive knowledge in the field of environmental inorganic and organic chemistry and to increase the certainity in assessing complex chemical aspects in the domains of environmental science and structural engineering. Furthermore, the lecture will provide a general survey of hydrochemically relevant classes of inorganic and organic pollutants as well as commonly used analytical techniques.
