Course objectives
At the end of this course students will be able to understand the global environmental problems. They will understand the consequences among the chemical structure of chemical substances, their physical-chemical properties and their fate in the environment and the impact of environment properties on this fate. They will be able to interpret the environmental fate of chemical substances, their environmental transport, interphase transport, phase equilibria and environmental biotic and abiotic transformation.
Syllabus
  • Conception of environmental chemistry education.
  • Global environmental problems. State of the environment in CR.
  • Chemicals in the environment – definitions, basic approaches. Environmental harmful chemicals. Environmental fate of chemicals. Environmental compartments, basic characteristics. Ecosystems – definition, relationships.
  • Biogeochemical cycles – general aspects, BGCC of carbon, nitrogen, sulphur, phosphor, metals.
  • Fate of chemicals in the environment – transport, transformation. Environmental interface and chemical equilibrium.
  • Parameters characterised properties of substances and environmental properties. Vapour pressure. Water solubility. Equilibrium organic phase-water. Distribution coefficient n-octanol-water. Organic acids and bases, constants of acidity. Diffusion. Environmental persistence. Chirality of chemicals. Occurrence of the chiral compounds in the environment and their fate. Relationships between chemical structure and reactivity.
  • Environmental transport of chemicals in air, water, soils and biota. Diffusion. Ficks law. Dispersion, advection, deposition, volatilisation, sedimentation, phase partitioning, leaching, biointake, elimination.
  • Abiotic environmental equilibria. Air-water equilibrium, Henry law. Air-aerosol equilibrium. Air-soil equilibrium. Air-biota equilibrium. Dry and wet atmospheric deposition. Sorption. Water-solid phase equilibrium (sediments, suspended sediments, soils). Leaching of soils, runoff.
  • Biotic environmental equilibria. Bioaccumulation. Biomagnification, uptake from food, uptake from sediments, uptake from water, food and sediments. Accumulation in terrestrial plants, roots uptake, foliar uptake. Accumulation in terrestrial invertebrates.
  • Abiotic transformations of chemicals. Chemical transformations. Non-reductive chemical reactions including nucleophilic group. Redox reactions. Photochemical transformation processes.
  • Biotic transformations of chemicals. Biodegradation, types of biodegradation reactions. Aerobic biodegradation and metabolic mechanisms, anaerobic biodegradation, kinetics of biodegradation. Biotransformation, effects of biotransformation on xenobiotics. Phases of biotransformation processes.

  • Environmental databases and information systems. Integrated register of pollution.
  • International conventions and activities focused on environmental substances.
  • New approaches in chemistry, green chemistry, sustainable chemistry.
  • Conceptual approaches in environmental analytical chemistry, environmental sampling, ultratrace analysis, environmental chemical monitoring.
