- Knowledge of the general mechanisms of action of chemical substances, both homogeneous and heterogeneous ones on organic systems.
- Knowledge of the risks of a continuous exposure to chemical agent on the human body.
- Assessment of that exposure on food and its repercussion on humans as users.
- To be able to differentiate scientifically about the benefit/risk balance of what it can represent the presence of certain substances added during the processes of food preparation.
As additional objectives it is important that students can:
- Discover the importance of the discipline in the studies of Nutrition and Dietary and their professional future.
- Acquire the specific toxicological vocabulary and terminology.
- Be concern by topics of general and/or social interest in relation with toxicology with repercussions on human health
- Use critically bibliographic sources.
- Encourage investigation on the Area of Toxicology
To sum up, it is intended that students can know the possible toxicological risks derived from food intake.

- The practical classes (12 hours) will consist of 4 practices. The content of this practical part will be linked and related to the theoretical part, so that both learning and skills are acquired and built as an integrated whole.
Each practice will include a brief theoretical introduction and practice scripts detailing the procedures to be developed.
- The interactive seminars (7 hours) will consist of complementary activities of the subject matter of the lectures, which will be taught by the teachers and/or by the students, being supervised by them.
- The students will work in groups related to the topics of the subject, to be presented orally in the classroom.
- The orientation of all the activities and tasks carried out by the students will be made by the teachers in group tutoring sessions (2 hours).

FINAL GRADE: expository controls (10%) + continuous evaluation of practices (20%) + evaluation of seminars (10%) + final test (60%)
The evaluation of the student will be carried out: by means of continuous evaluation (controls of the expository classes, evaluation of the practices, completion of work) and final exam.
Practises assessment (20% of the final score) will be carried out by evaluating the attendance to the practices and the evaluation of the memory of the same (15%), and final exam at the end of the practices (5%).
Competences assessed: CB1, CT3, CG11, CE15.
The completion of work (10% of the final grade) will consist of the preparation and oral presentation of a group work on topics related to the subject, assumptions, etc.
Competences assessed: CB1, CB2, CB3, CB4, CB5, CG5, CG6, CT1, CT3, CT4, CT5, CT7, CG11, CE15.
The final exam will mean 60% of the grade for the subject and will consist of short answer questions and/or test type. Students must obtain a score equal to or greater than 50% of the maximum possible score for this test so that score is taken into account in the final grade for the course.
Competences assessed: CB1, CB5, CG11, CE15.
Attendance at practices, tutorials and seminars is mandatory to pass the subject.
The qualification of the Continuous Assessment (expository controls, practices and monographic works) will be kept for the following courses.
When the students have not passed the continuous assessment, or practices made, or final exam, they will obtain the grade of “Not Presented”.

- Seminars: 7 lecture hours/10 h autonomous work
- Practices: 12 hours classroom/18 h autonomous work
- Works: 2 lecture hours/10 h autonomous work
- Group tutorials: 2 h lecture
- Examinations and review: 2 lecture hours/12 h autonomous work
- Attendance at lectures
- Attendance and active participation in practical classes
- Consultation of the recommended bibliography
- Have support of individual tutorials to solve issues
