Presentation Transcript

  1. Welcome BSc (Hons) Environmental Chemistry

  2. Environmental Chemistry BSc • School of Earth & Environment • Chemistry, Colour chemistry

  3. Degree Programme

  4. Fieldcourses • Sampling in field • Atmospheric • Geochemical • Coniston Copper Mines • Carrock Fell • Arran

  5. Environmental Samples • Pollution - acid mine drainage • coal, copper, lead mining • FeS2 stable in absence of oxygen • Oxidised to H2SO4 and Fe(III) • Fe3+ “ochre” precipitate • Acid solubilises lots of HM – aluminium • Pyrite + oxygen + water  H+ + Fe(II)aq + SO42- • Fe(II)(aq) + oxygen + hydroxide  Fe(OH)3 (ppte)

  6. Acid Mine Drainage • Oxidation of FeS2 • Pollutants - acid, Fe, other heavy metals • Yorkshire, global

  7. Environmental Samples • Understanding processes • Acid mine drainage • Effluent from mine / tailings • Dilute and disperse to river • Chemistry & other (microbiology, dispersion, impact)

  8. Arsenic • Bangladesh – surface water typhoid & cholera • Groundwater – wells; 25% As contamination • 25 million people affected • Fieldcourse - As

  9. Arsenic in Bangladesh Arsenic associated with aquifers at intermediate depth (very shallow and deep (>150m) wells are unaffected) Water used for drinking, cooking, cleaning and agriculture Effects of poisoning take from 5-15 years to become apparent Simple technologies can help – rusty nails and alum in water!

  10. Environmental Chemistry BSc • Further studies - MSc; PhD. • Field chemists – landfill & river monitoring • Consultants - EA; DEFRA • Career chemists – Water companies, UKAEA, consultancies • Teaching - PGCE

  11. Our strengths • Young, energetic committed staff • External contributors • Fieldwork • World class research + real world links • Student choice • Facilities – library, computing • External endorsement (QAA) • Internal endorsement (University, students) • Vibrant student population • Leeds

  12. Our own mission To provide a friendly and stimulating environment in which students can acquire environmental knowledge and related applied skills, and experience rapid and fulfilling personal and intellectual development. Our University is a place for exploration.
