Course requirements:

Enrolment in a relevant PhD programme. Comprehensive knowledge of organic environmental chemistry, and with experiences in chemical analysis or successful participation in AT-831 and AT-830.

Academic content:

Today, a large number of organic chemicals have been identified as contaminants of concern in the Arctic environment. Their fate and transport in the environment from both long-range and local sources are a key area of research. Despite often being found at low concentrations, they can have a serious impact on the ecosystem. Detection, identification, and quantification of these chemicals at ultra-trace levels requires specialized sampling and analytical procedures.

The course will introduce PhD students to the most commonly used methods for the preparation and quantification of organic contaminants in samples from the Arctic. What is feasible with various methods and what are the limitations and potential complicating factors. Focus will be put on the application of sampling and analysis methods and discussion of challenges and pitfalls through practical exercises and experiments with Arctic environmental samples collected during field work in the vicinity of Longyearbyen.

The students will be introduced to the general scientific principles of modern analytical quantification methods for organic chemicals; learn through active field and laboratory work about the importance of sampling/sample treatment as an integrated part of trace analyses. They will evaluate the complete process leading from sample site selection, sampling and quantification based upon modern analytical technology and how these data can be used in estimating environmental risk.

Learning outcomes:

Knowledge
Upon completing the course, the students will:

  • appreciate the role of analytical chemistry in determining fate and transport of organic contaminants for the overall environmental risk assessment in Arctic environments
  • understand the challenges of sampling and analyses of Arctic samples given the often low concentrations present.
  • understand the requirements underlying modern analytical chemical methods for the quantitative determination of environmental pollutants in Arctic environments
  • understand and further develop quality criteria for the development of modern and advanced trace analytical methods for identification and quantification of emerging organic pollutants
  • know and actively apply the scientific principles and requirements underlying modern analytical chemical methods for the quantitative determination of environmental pollutants in Arctic environments
  • appreciate and actively develop logistical and technological requirements for conducting relevant fieldwork on environmental pollutant research under Arctic conditions.
  • understand the role of organic environmental chemistry in risk assessment of contaminants in the Arctic

Skills
Upon completing the course, the students will be able to:

  • select and actively apply suitable strategies and technologies for a sound and reliable determination and quantification of organic pollutants based on scientific evaluation of available analytical instrumentation
  • further develop available analytical procedures along the required needs for new contaminants of emerging concern
  • perform a principal method validation based upon standard quality control (QC) criteria accepted in modern analytical laboratories
  • critically evaluate the quality of published data based upon QC protocols given in the respective reference and select reliable methods based upon scientific studies published in peer-reviewed journals
  • apply uncertainty in the data for the applied analytical methods as a framework for subsequent statistical evaluation and risk assessment.

General competences
Upon completing the course, the students will be able to:

  • understand validated analytical workflows as part of on-going trace analytical processes in academic and commercial laboratories
  • conduct method development on new quantitative trace analytical methods on contaminants of emerging concerns as scientific team-leader
  • decide on the use of specific analytical technologies and methods for a reliable quantification of organic chemicals of concern using science-based methods.

Learning activities:

The course extends over ca. 6 weeks including compulsory safety training, and is run in combination with AT-324.

The AT-824 students will actively participate in field work and laboratory experiments. They will join an assigned student group (together with AT-324 students) and contribute to the laboratory report as a part of the AT-824 compulsory learning activities.

In addition, the AT-824 students must prepare a written comprehensive scientific report on assigned experiments including a scientific literature-based topic associated to experiments (4500 words; background, experimental section, results put into a scientific context, motivation, including tables, figures and key references).

Total lecture hours: 30 hours.
Laboratory work: 60 hours.
Report work and supervision: 40 hours.
Field excursion: 3 days

Compulsory learning activities:

Attending all lectures and seminars, and field excursions.
All compulsory learning activities must be approved in order to sit the exam.

Assessment:

Method Duration
Percentage of final grade
Written report in manuscript form 50%
Oral exam (report discussion) 50%

All assessments must be passed in order to pass the course.
Each assessment is graded, and subsequently combined into a single grade. Partial grades for each assessment will be available. 

Application deadline: 15 October 2022
