Course objectives
The aim of the course is to get an overview and good orientation in environmental analytical chemistry of organic and inorganic pollutants. The aim is to provide a quality information bases that will enable students to design and compare different methods for sampling, processing and analyzing of environmental samples.
Learning outcomes
At the end of the course, students should be able to:
- describe a purpose and principles of the activities focused on screening and monitoring a presence of antropogenic chemicals in the environment.
- discuss differences between various groups of organic pollutants. - select the best methods for the individual groups of chemicals.
- distinguish between specific sampling methods for determination of volatile, non-volatile, polar and non-polar compounds in air, water, sediment, soil and biota.
- review the analytical techniques for the sample preparation, clean-up and fractionation.
- compare the separation and identification techniques and their applicability for determination of various organic chemicals in the environmental samples.
- illustrate their specificity on the major groups of organic compounds polluting the environment.
- introduce the quality assurance/quality control measures. - understand the whole concept of chemical analysis of the environmental samples.
- characterize the specific problems of this field. - interpret the analytical results.
Syllabus
  • A. Introduction to environmental analytical chemistry
  • 1. Environmental monitoring: purpose and principles, international measures and programs
  • 2. Specific problems of the environmental analysis
  • 3. Sampling methods for air (gas and particles), atmospheric deposition (wet and dry), water, sediment, soil and biota
  • 4. Quality assurance/quality control measures, interpretation of the analytical data
  • B. Analytical chemistry of organic pollutants
  • 1. Analytical techniques for the sample extraction (solvent extraction, liquid-liquid extraction, extraction on the solid phase, head-space, purge-and-trap), clean-up and fractionation of the environmental samples
  • 2. Review of the separation and identification techniques with the special focus on chromatography (applications of the gas, liquid and gel permeation chromatography) and mass spectroscopy (electromagnetic sector, quadrupole, ion trap analyzers)
  • 3. Application of the above-discussed techniques for determination of the most important groups of environmental pollutants (polychlorinated biphenyls, organochlorine pesticides, polyaromatic hydrocarbons, volatile hydrocarbons)
  • B. Analytical chemistry of inorganic pollutants
  • 1. Toxic elements in water, soil, sediment, air and biological matrices. Techniques of extraction and decomposition of samples (open vessel decomposition, pressured decomposition, microwave assisted decomposition ...). Detection of elements by atomic spectrometry techniques (AAS, ICP techniques, NAA, RTG fluorescence ...). Speciation analysis. Practical aspects of elemental analysis.
  • 2.Water analysis - water pH values and their measurements, carbonate balance, dissolved and undissolved substances, neutralization capacity, chemical and biochemical consumption of oxygen. Determination of anions in water (titration, spectrophotometry, ion selective electrodes, electromigration methods, ion chromatography).
  • 3. Air analysis - determination of sulfur compounds, nitrogen compounds, ammonia, ozone and CO. Chemical composition of atmospheric aerosols.
