Risk assessment and the ability to prevent harmful effects during working with chemicals.

Course enrolment requirements and entry competences required for the course


Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After course students will be able to :
1.definition of basic concepts and history of chemical ecology
2.the origin of the chemical constituents in the ecosystem
3.classification and labelling of hazardous chemicals
4.transport mechanisms in the environment
5.sources of pollution as a result of human activity
6.interactive impact of pollutants to process the obtained knowledge of the toxicological and ecotoxicological information

Grading and evaluating student work in class and at the final exam

During the semester, the two partial test to check if the knowledge of students from courses included material. During the semester students will be selected from the lecture topic to make a seminar that will affect the final grade. After completion of the semester, students take a written exam courses included material from the seminar. If the student meets at one of the partial tests during the semester, material from passing the test does not need to take the written exam. After passing the written part of the exam, the oral exam. Prior to joining the laboratory exercises, students’ knowledge of material from the respective exercise will be verified by tests. All exercises must be passed all preliminary exams and completed. The student has the right to exercise fail one exercise, but you will catch up at the end of the semester. For all aspects of teaching evaluation will be conducted according to the following criteria: 86% excellent. The final grade will be the arithmetic average of ratings from exercises, written assessment and oral examination.

Quality assurance methods that ensure the acquisition of exit competences

Quality assurance will be performed at three levels:
(1) University Level;
(2) Faculty Level by Quality Control Committee;
(3) Lecturer’s Level.
