| Introduction | Human population growth. Major environmental problems in Europe. Ecotoxicology. |
| Pollutants | Major types and features Inorganic pollutants: metals and anions Organic pollutants Organometals Gases |
| Toxicokinetics | Mechanisms for pollutant accumulations. Uptake. Biotransformation and detoxification of metals and metaloids. Biotransformation of organic pollutants. Excretion. Bioaccumulation Factor (BAF), Bioconcentration Factor (BCF), and Accumulation Factor. Kinetics. |
| Bioamplification along the trophic chain | Bioamplification. Trophic transfer and Bioamplification factor. Examples of bioamplification in metals and organic pollutants. |
| Bioaccumulation and pollutant detection (Retrospective Ecotoxicology I) | Bioavailability. Factors of pollutant bioavailability. Use of bioaccumulators. Requisites of a good bioacumulator. |
| Toxicodynamics: biochemical and histological effects | Protective and non protective bgiochemical changes. Molecular toxicity mechanisms. Modes of toxic actions in organic pollutants. Examples of molecular mechanisms. Cytotoxicity and necrosis. Damage to genes and chromosomes. |
| Physiological effects | Subletal effects. Effects on growth, development, reproduction, physiology and behaviour. Trade-off between detoxification and production. |
| Biomarkers (Retrospective Ecotoxicology II). | Classification, especificity and relationship with damaging effects. Requisites of a good biomarker. Examples of biomarkers. Use of biomarkers. |
