  1. Student Research projects on urban geoscience issues: Volcanic Hazards, Urban Waste and Beach Hazards Cristina P. De Campos Dept of Earth and Environmental Sciences / Munich GeoCenter

  2. Volcanic Hazards: Volcanic Hazard = f (Volcanic activity X Urban Environment) Naples

  3. Students projects: Volcanologic Excursion : 10 days trip to the Eolian Islands or Canary Islands

  4. Waste Hazards:

  5. Waste Hazards: Soraya Heuss-Assbichler Mineralogy ofMuniciple Solid Waste Incineration Residues

  6. 20 kg material flow in a MSWI APC residue Bottom ash Boiler ash Scrap metal Volume reduction at about 90 vol.- %

  7. metallic Aluminium 2 Al + 6 H2O  2 Al(OH)3 + 3 H2 • pH 4,5 – 8,8protective oxide film • pH > 10 • pH < 4 increasing solubility • Cl - Milieu pitting corrosion

  8. B A Hc AlOOH Al Ett C Different types of corrosion textures in altered bottom ashesresulting in hydrogen production at alkaline reaction conditionsA) type 1 - Al particle surrounded by a rim of aluminum hydroxide, B) type 2 - multiphase rim around Al: Al hydroxide, hydrocalumite, monosulfate or ettringite, C) detail image of multiphase rim, (BSE image)

  9. Concentration of hydrogen in landfill gas observed in a monofill in S-Germany LEL: lower explosion limit for hydrogen in contact with air

  10. Beach Hazards Federal University of Rio de Janeiro UFRJ

  11. Final maps
