Environmental Chemistry KRA211



KRA211 is a Semester 1 unit (12.5%) that covers aspects of environmental chemistry. This unit will develop an understanding of the chemical behaviour of important elements and compounds in the environment, with an emphasis on aquatic, marine and atmospheric chemistry. Topics include general, inorganic and organic chemistry; pollutants in the aquatic environment and wastewater treatment; introductory soil chemistry; the Greenhouse Effect and urban air pollution.
The Unit not only meets the needs of chemists, it has direct relevance to students with interests in earth sciences, life sciences and environmental science.

Please check that your computer meets the minimum System Requirements if you are attending via Distance/Off-Campus.

Units are offered in attending mode unless otherwise indicated (that is attendance is required at the campus identified). A unit identified as offered by distance, that is there is no requirement for attendance, is identified with a nominal enrolment campus. A unit offered to both attending students and by distance from the same campus is identified as having both modes of study.

Learning Outcomes

  • Have an understanding of the importance of the chemistry of metals in the environment and their interactions with naturally and unnaturally occurring species.
  • Be able to briefly discuss the composition of atmospheric aerosols and particulate pollution, and understand the terms TSP, PM10, and Air NEPM, the means by which particulate pollution is measured, and the technology used to reduce particulate pollution.
  • Be able to discuss the sources, contributions/potential contributions and fates of the main greenhouse gases/species, namely water vapour, carbon dioxide, methane, ozone, nitrous oxide, CFCs and aerosols, to global warming.
  • Have an understanding of the importance of dissolved oxygen in an aquatic system, how its concentration can be estimated and/or measured, how it is depleted and how this effect is measured.
  • Know what acidity, alkalinity and hardness are, how they are determined and their role in the environment.
  • Know what surfactants, PCBs, PBBs and pesticides are, their uses, relative toxicities and stabilities, their environmental impacts, and how their levels are measured.
  • Know how drinking water is “purified”, and how sewage and industrial waters are treated before release into the environment or re-use (including for drinking).
  • Know the major inorganic and organic components of soil, how they are classified and interrelated, and understand the role these components in detoxifying and stabilising pollutants.
