What is this course about?

Description

This specialised course examines how environmental contaminants cause harm, and the structured methods to estimate and manage that harm in real-world exposure scenarios. It covers toxicokinetics (toxicant absorption, distribution, metabolism, excretion) and toxicodynamics (toxicant effects). You will learn how environmental toxicology complements epidemiology in providing risk-based evidence to inform safe exposure standards and risk communication, and is central to regulatory and policy frameworks used by agencies to protect public and environmental health.

All - Assessment Task 1:Environmental health risk assessment report
Goal: 
To demonstrate your knowledge and understanding of toxicological principles and skills in conducting and communicating a screening level risk assessment for a specific environmental toxicant.
Product: Artefact - Technical and Scientific, and Written Piece
Format: 
You will source, synthesise and appraise relevant scientific data and information relevant to each of the 4 steps of risk assessment and communicate the findings in a written scientific report suitable for a professional health regulator audience.  
You will select a specific environmental toxicant for this task which will need to be approved by the course coordinator. You will then source, summarise and critically appraise scientific evidence relevant to and presented under the following risk assessment steps (Hazard Identification, Dose-response assessment, Exposure assessment and Risk characterisation).  
The report will conform with specific guidelines provided and tables and figures will be required.  
Further information will be provided on Canvas. 
This report should be included in your Professional Environmental Health e-portfolio.

All - Assessment Task 2:Professional oral presentation
Goal: 
To analyse and communicate levels of health risk for a defined real-world environmental exposure scenario.
Product: Oral
Format: 
You will produce a recorded 20-minute, oral presentation that builds on the generic risk assessment of your chosen toxicant from Task 1. You will nominate a specific community likely to be exposed to your toxicant and cover the following three elements. 
1. Synthesise evidence and use judgement to characterise the current situation (risk levels) by: 
 1.1 Estimating the likely levels of exposure to the toxicant by members of your defined community, and 
 1.2 Estimating the prevalence of health conditions shown to be associated with the toxicant within your designated community. 
2. Distinguish the key roles and responsibilities of a range of stakeholder groups/agencies for managing the health risks faced by members of your community. 
3. Outline further research needs that would better inform risk reduction strategies. 
Further information will be provided on Canvas.
Criteria:
No. Learning Outcome assessed
1 
Relevance and accuracy of the evidence provided for your community for estimated levels of exposure to the toxicant and health outcomes

Assessment: Academic Integrity

Academic integrity is the ethical standard of university participation.  It ensures that students graduate as a result of proving they are competent in their discipline.  This is integral in maintaining the value of academic qualifications. Each industry has expectations and standards of the skills and knowledge within that discipline and these are reflected in assessment.

Academic integrity means that you do not engage in any activity that is considered to be academic fraud; including plagiarism, collusion or outsourcing any part of any assessment item to any other person.  You are expected to be honest and ethical by completing all work yourself and indicating in your work which ideas and information were developed by you and which were taken from others. You cannot provide your assessment work to others. You are also expected to provide evidence of wide and critical reading, usually by using appropriate academic references.

In order to minimise incidents of academic fraud, this course may require that some of its assessment tasks, when submitted to Canvas, are electronically checked through Turnitin.  This software allows for text comparisons to be made between your submitted assessment item and all other work to which Turnitin has access.
