Aims and objectives

General aims for second cycle education

Second-cycle courses and study programmes shall involve the acquisition of specialist knowledge, competence and skills in relation to first-cycle courses and study programmes, and in addition to the requirements for first-cycle courses and study programmes shall

  • further develop the ability of students to integrate and make autonomous use of their knowledge
  • develop the students' ability to deal with complex phenomena, issues and situations, and
  • develop the students' potential for professional activities that demand considerable autonomy, or for research and development work.

(Higher Education Act, Chapter 1, Section 9)

Course objectives

Knowledge and comprehension
After having completed the course the student shall

  • be able to explain how the chemical properties of environmental toxicants affect the uptake, toxicity, metabolism and elimination of the compounds from the body,
  • be able to illustrate how toxicants can exercise their effect at the molecular, cellular, organ, organism and population level,
  • be able to elucidate mechanisms for chemically induced neurotoxicity, endocrine toxicity and genotoxicity, and
  • be able to describe different bioanalytical methods and their importance to identify mechanisms of action of environmental toxicants.

Skills and ability
After having completed the course the student shall

  • have an increased ability to investigate the toxic effects of chemicals on molecular and cellular levels,
  • have an increased ability to plan and perform an experimental study and present the results in writing and orally, and
  • communicate and discuss the experimental results.

Values and attitude
After having completed the course the student has the ability to

  • critically evaluate experimental data and theoretical interpretations,
  • seek and critically evaluate primary scientific information in the area, and
  • reflect over group work, their own role within the group, and their own learning process.

Main content of the course

The environmental toxicology course deals with toxicological effects of various foreign substances (xenobiotics) on living organisms and toxicological methodology. Students learn about how humans and other organisms are exposed to environmental pollutants and how the physiochemical properties are linked to absorption, distribution, metabolism, elimination (toxicokinetics) and toxicological effects of the compounds in the body (toxicodynamics). Emphasis will be placed on the effects of the compounds at molecular, cellular, and organism levels and how the effects can be studied. The course also gives insight into environmental and human health risks with different classes of chemicals and the link between the chemical community, chemical exposure and public health.

The course contains a practical laboratory work where the students study the occurrence of organic pollutants in environmental samples. Students design the practical work, which include sampling plan, sample collection, sample preparation and mechanism specific analysis of the samples.

Teaching methods

Teaching is done in the form of lectures, group assignments, laboratory sessions and seminars.
If the course only receives a few registered participants, the teaching methods described above can be completely or partly replaced by supervision.

Students who have been admitted to and registered on a course have the right to receive tuition and/or supervision for the duration of the time period specified for the particular course to which they were accepted (see, the university's admission regulations (in Swedish)). After that, the right to receive tuition and/or supervision expires.

Examination methods

Theoretical Part, 7 credits (Code: A001)
Written examination.

Practical Part, 3 credits (Code: A002)
Group wise written and oral presentations of laboratory work. Attendance and active participation in laboratory work and oral presentations. Active participation in seminars.


For students with a documented disability, the university may approve applications for adapted or other forms of examinations.

For further information, see the university's local examination regulations (in Swedish).

Comments on examination methods

Absence from Mandatory Course Component
If a student is absent from a mandatory course component, the examiner determines if the student will be able to make up for the component during another scheduled class of the same kind. Otherwise, the student is referred to the next time the course is offered. As an exception the examiner may decide on substitute assignments. These shall then be carried out before or shortly after the end of the course.

Grades

According to the Higher Education Ordinance, Chapter 6, Section 18, a grade is to be awarded on the completion of a course, unless otherwise prescribed by the university. The university may prescribe which grading system shall apply. The grade is to be determined by a teacher specifically appointed by the university (an examiner).

In accordance with university regulations regarding grading systems for first and second-cycle courses (Vice-Chancellor’s decision ORU 2018/00929), one of the following grades shall be used: Fail (U), Pass (G) or Pass with Distinction (VG). For courses that are included in an international Master’s programme (60 or 120 credits) or offered to the university’s incoming exchange students, the grading scale of A-F shall be used. The vice-chancellor, or a person appointed by the vice-chancellor, may decide on exceptions from this provision for a specific course, if there are special grounds.

Grades used on course are Fail (F), Sufficient (E), Satisfactory (D), Good (C), Very Good (B) or Excellent (A).

Theoretical Part
Grades used are Fail (F), Sufficient (E), Satisfactory (D), Good (C), Very Good (B) or Excellent (A).

Practical Part
Grades used are Fail (U) or Pass (G).

For further information, see the university's local examination regulations (in Swedish).

Comments on grades

To obtain a passing grade for the course as a whole, a minimum of grade E is required for the theoretical part on the course as well as Pass (G) on the practical part, which includes participation in laboratory work, oral presentations and obligatory seminars. The final course grade is based on the result of the theoretical part.

Specific entry requirements

A first-cycle qualification comprising 90 credits in the main field of chemistry or biology. Or a first-cycle qualification comprising 90 credits in the main field of environmental science where toxicology is included. The applicant must also have qualifications corresponding to the course "English 6" or "English B" from the Swedish Upper Secondary School.

For further information, see the university's admission regulations (in Swedish).

Transfer of credits for previous studies

Students who have previously completed higher education or other activities are, in accordance with the Higher Education Ordinance, entitled to have these credited towards the current programme, providing that the previous studies or activities meet certain criteria.

For further information, see the university's local credit transfer regulations (in Swedish).

Other provisions

The teaching is in english.
