CHEM19085 - Environmental Chemistry

General Information

Unit Synopsis

This unit examines • air pollution: ozone depletion, sulfur oxides, photochemical smog and greenhouse effects; • water pollution; • inorganic and organic pollutants, surfactants and detergents; • hazardous wastes: classification, treatment, disposal; • pollution monitoring: sampling procedures, analytical methods and modelling techniques. You will be presented with the ecological and health effects of chemical pollution and these will be discussed. Renewable energy and energy utilisation is investigated. If you are a Distance education student, you will be required to attend a residential school for this unit.

Important note: Students enrolled in a subsequent unit who failed their pre-requisite unit, should drop the subsequent unit before the census date or within 10 working days of Fail grade notification. Students who do not drop the unit in this timeframe cannot later drop the unit without academic and financial liability.

Attendance Requirements

All on-campus students are expected to attend scheduled classes – in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Assessment Overview

Recommended Student Time Commitment

Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Assessment Tasks

Assessment Task Weighting
1. Written Assessment 30%
2. Practical and Written Assessment 50%
3. Online Test 20%

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%).

Feedback, Recommendations and Responses

Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.

Source: Student Evaluation
Feedback
The lectures need to perhaps be reordered so that the information on arsenic, heavy metals, greenhouse effect is on the lecture schedule before Assessment 1.
Recommendation
Excellent suggestion that will be considered.
Action Taken
This suggestion has been incorporated in the 2020 delivery. Assessment 1 did not have any coverage of the Greenhouse Effect.
Source: Student Evaluation
Feedback
It was felt that the exam re-assessed the same topics that were previously covered in the first Assignment. It would be good if the exam focused on Weeks 6-12 content.
Recommendation
Excellent suggestion. There will be no duplication of content from Assessment 1 into the Final Examination.
Action Taken
This suggestion has been incorporated.
Source: Student Evaluation
Feedback
Please provide some pre-lab videos on basic techniques for res school, e.g. pipetting, dilutions so these can be refreshed before the res school.
Recommendation
We will consider directing students to relevant videos online that explain these laboratory skills.
Action Taken
The next cohort of students enrolling in the Unit will have completed two chemistry units, as recently as Term 2 of Year 1. The experiments in these units reinforce practical skills, so we expect students to have greater laboratory skill sets in the next offering of the Unit. However, we will still direct them to videos in case students feel that they would need a refresher.

Feedback
The Moodle page was easily accessible and well laid out.
Recommendation
A comprehensively detailed Moodle platform will be continued.
Action Taken

Feedback
Some lectures had poor audio.
Recommendation
The lectures for the unit were recorded in the office and it was found rather late that wired headsets tend to pick up a lot of noise from the wire constantly making contact with the device. To address these, the use of wireless headsets with mics in subsequent lecture recordings has been successful. These headsets will continue to used for future desk-based recordings. Live lectures remain an option for the next offering too, and these may address some of the issues.
Action Taken
Nil.
Source: Have Your Say
Feedback
Better interaction with students would be good.
Recommendation
In a normal term, by the time the feedback was open, there would have been a successful residential school, and a lot of positive interactions tend to happen from this point onward. The past feedback specifically supports this observation, so it is hoped that we can give students positive experiences in the residential school and it contributes to a more positive experience.
Action Taken
Nil.
Unit learning Outcomes

On successful completion of this unit, you will be able to:

  1. Understand the chemical principles relating to the chemistry of the different spheres of the environment: atmosphere, hydrosphere, lithosphere and biosphere
  2. Use laboratory skills to make reliable analytical measurements to assess the quality of water, air, soil and food sources
  3. Be familiar with the important environment regulating authority and environmental guidelines
  4. Use research skills to obtain information relating to environmental chemical concepts, environmental issues and current approaches to solve these.
