Forensic geochemistry 1300-WFRG-OG

Course comprises:
1. Properties of pure substances: phase transfer, diffusion, sorption, acid-base chemistry
2. Polymers: homopolymers and copolymers
3. Thermodynamics and kinetics of chemical transformations of organic pollutants: hydrolysis, redox transformations and photochemistry
4. Biological transformations of organic pollutants
5. Sampling and analysis of organic and inorganic (plastic) pollutants
6. Human exposure to PAHs and effects
7. Source of PAHs
8. Analytical methods
9. PAHs in air, water, soil, sediment, sewage sludge and food
10. PAHs in coal and petroleum products
11. Toxicity of PAHs
12. Radioactive isotopes application in environmental research:
I. Mining impact on the environment - radioactive hazard. Measurements of lead and uranium-series isotopes using ICP-MS (theory), and alpha/gamma spectroscopy (exercise in the lab in the ING PAN). Selected examples: uranium and lead mines, phosphogypsum waste dumps.
II. Post-Chernobyl pollution monitoring - spatial distribution of cesium 137Cs in Europe and Poland; distribution and migration of 137Cs in the aquatic ecosystems; bioaccumulation of cesium isotopes. The other side of the coin - cesium 137Cs as a useful tool in dating lake sediments and as a soil erosion tracer.
III. Fukushima pollution monitoring techniques
13. Heavy metal contamination in soils and water – migration of heavy metals in soil and water. Kinetics and thermodynamics of sorption and desorption processes, crystallization of mineral phases in highly contaminated areas (examples of weathering zones of polymetallic deposits).
14. Bioremediation.

ogólnouniwersyteckie

Założenia (opisowo)

It is assumed that the student has knowledge of natural sciences and knows the terminology of geology at the bachelor's level. Basic knowledge in organic geochemistry is also helpful.

Efekty kształcenia

The student will learn about the methodology and interpretation of geochemical data, non-biomarker compounds (PAHs and heterocyclic aromatic hydrocarbons), polymers, radioactive isotopes and heavy metals in particular. The student will learn techniques for the geochemical evaluation of PAHs and sources of petroleum- and heavy metal-contaminated areas. In addition, the student will familiarize the methods and programmes (e.g. Xcalibur, ChemStation Data Analysis) used to interpret aromatic compounds.

Kryteria oceniania

The examination requirements cover the scope of material presented at the lectures. The exam is in writing and includes a test and descriptive part.
