ENVH12003 - Environmental Toxicology

General Information

Unit Synopsis

Environmental toxicology is the study of the nature, properties, effects, and detection of toxic substances in diverse environments and those exposed. In this unit, you will study an introduction to basic toxicology from a public health perspective, focusing on developing an understanding of the principles of the discipline and the concepts relating to environmental exposures. Topics that will be covered include routes of exposure, the concept of dose, dose-response relationships, absorption and distribution of toxicants, biotransformation and elimination, target organ toxicity, carcinogenesis, mutagenesis, teratogenesis and risk assessment. You will examine toxicants of interest within community and occupational environments as well as how they are tested and regulated. You will practise your professional skills by reviewing case studies and special topics of interest.

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. Online Quiz(zes) 20%
2. Written Assessment 40%
3. Take Home Exam 40%

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: Personal reflection
Feedback
Students did not attend tutorials, which was reflected in grades.
Recommendation
In the early part of the term, the importance of attendance at tutorials should be emphasised. Promote the survey to ensure an appropriate day/time is chosen.
Action Taken
Recommendation was actioned, however had little impact as although some completed the survey, no students attended tutorials.
Source: Unit Evaluation
Feedback
One student commented that the pace of the lectures was a little fast.
Recommendation
Make students aware of the pause and rewind option and, particularly, the importance of attending tutorials to have questions answered.
Action Taken
Recommendation was actioned.
Source: Observations
Feedback
Students did not attend tutorials.
Recommendation
Continue to emphasise that participation in tutorials is highly recommended and that sessions are not recorded if there is no attendance. Consider commencing delivery from Week 2 instead of waiting until Week 3, to develop a routine.
Action Taken
Nil.
Source: Observation
Feedback
Students were less engaged
Recommendation
Introduce some new activities using H5P to boost engagement.

Unit learning Outcomes

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

  1. Define fundamental toxicological concepts
  2. Identify and classify a range of common toxicants and their environmental sources
  3. Explain the dose-response relationship and its implications and applications
  4. Describe fundamental processes and endpoints relating to toxicants within the human body
  5. Apply the principles of risk assessment and risk management to toxicological situations
  6. Discuss major issues in environmental toxicology relating to exposures from natural and anthropogenic sources
  7. Critically consider the ethical and regulatory implications of toxicological research, associated uncertainties and risk communication.

Bachelor of Public Health (Environmental Health)

Foundation and applied environmental toxicology (LOs 1, 2, 3, 4 & 6) are identified as underpinning skills and knowledge in Part 2 of the Environmental Health Australia Skills & Knowledge Matrix, used as the basis for accreditation of the Bachelor of Public Health (Environmental Health) course. Methods of risk assessment and management (including as applied to toxicological issues) (LO 5) and the use of evidence in regulatory practice (LO7) are also identified as underpinning knowledge. Additionally, toxicology is an integral part of many of the activity-specific skills and knowledge identified in Part 3 of the Matrix.

Bachelor of Occupational Health & Safety

An understanding of toxicology is also important to support studies in Occupational Hygiene, considered a core knowledge area in the Safety Institute of Australia's Body of Knowledge, proposed to be used for accreditation of OHS courses within Australia.
