Learning Outcomes

This is a laboratory course supplemented by lectures that focus on selected analytical methods used to determine water quality and pollution. The course covers introduction to water quality parameters (with a focus on emerging and persistent pollutants), pollutants properties and measurement techniques. Fate and transport of pollutants in relation with their physicochemical properties, risk assessment in relationship to water quality are also covered.

Upon successful completion of this course the students will acquire new knowledge and specific skills on the following subjects:

  • To understand the basic and critical qualitative characteristics of water samples, their connection to sources of pollution.
  • To have knowledge of the tools and analytical techniques for determining the qualitative and quantitative characteristics of aqueous samples.
  • To gain knowledge on the basic principles of operation of modern and advanced analytical techniques for the determination of metals and organic pollutants in aqueous samples
  • To gain knowledge on basic principles of sampling and chemometrics.
  • To evaluate water characteristics in order to draw conclusions about the level and type of pollution.
  • To gain laboratory experience on a range of analytical water pollution assessment methodologies
  • To understand the principles of operation on a range of analytical instrumentation
  • Trained in laboratory safety rules
