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. |
Toxicity assays (Porspective Ecotoxicology I). | Dose-response relationship. Types of assays. Data analyses. Toxicity curves, mean lethal time and threshold LC50. Data analyses in chronic assays: NOEC, LOEC y MATC. Application Factor. |
Prediction (Prospective Ecotoxicology II) | Prediction at individual level: QSAR. Prediction at ecosystem level: SSR. |
Changes in community composition (Retrospective Ecotoxicology III). | Indicator species. Relative abundance. Saprobic systema and biotic indexes. Diversity. Comparisson with reference communities. |
