Objectives

The main objective of this course is to provide knowledge and develop skills in Aquatic Toxicology. These skills encompass the themes of general toxicology, risk assessment, and response mechanisms involved in detoxification of various types / classes of compounds (eg, PAHs, PCBs, pesticides, metals, dioxins / dibenzofurans, natural and synthetic estrogens, pharmaceuticals) . Will also emphasized the role of biomarkers and their utility in environmental toxicology.

Learning outcomes and competences

It is expected that students gain skills in the study area, being able to assist in the evaluation of risk situations, the proposed solutions for the prevention and learn to identify the analytical means to diagnose the degree of environmental pollution.

Program

Theoretical programmatic content (Summary)

• Introduction to toxicology and its evolution towards aquatic toxicology;


• Types and mechanisms of response to toxicants;


• Phases of exposure, toxicokinetics, and toxicodynamics of toxic agents in the aquatic environment;


• Evaluation of toxic responses.


• Discussion of toxic responses at the level of biological organization, molecule/biochemistry, cell, and animal until its impact on populations, communities, and ecosystems;


• Understanding of the metabolism and effects of specific groups of common environmental pollutants in the aquatic environment (e.g. polycyclic aromatic hydrocarbons, polychlorinated biphenyls, pesticides, metals, dioxins, dibenzofurans, natural and synthetic estrogens, pharmaceutical products);


• A brief introduction to the main analytical methods used in field analyses;


• Use and development of bioindicators and biomarkers;


• Determination of bioaccumulation and bioamplification factors;


• Risk assessment.

Practical programmatic content (Summary)

Standardized toxicity tests using freshwater or saltwater invertebrate species (microcrustaceans). Elaboration and interpretation of experimentally obtained dose-response curves.

Eligibility for exams

Presence to three quarters of classes taught and realization of special works.

Calculation formula of final grade

The evaluation will be conducted during class (40%) and a final exam (60%). The evaluation will be conducted during class (40%) and a mandatory final exam (60%). In both components students must achieve a minimum of 10/20 values.

Examinations or Special Assignments

Presentation of a seminar on environmental pollutants that most affect the aquatic environment (group work). Preparation / presentation of a research project on the topics discussed in the seminars.

Special assessment (TE, DA, ...)

Student workers (TE), association leaders (DA) and other students with special status will be evaluated similarly to regular students. However, in cases where the law exempts failure by faults in the classes that will be evaluated (the DC component) are those in which the student will attend.

Classification improvement

The grade improvement will only be possible for the component assessed in the final exam.
