Details of requirements
You are given a name of a hazardous chemical, LEAD. You are required to research detailed information on the relationship between exposure to the chemical (dose) and harm. You will need to research both human and animal studies to develop a view of the dose-effect and dose-response relationships. The research studies should be reviewed to try to ascertain the threshold of harm for that chemical.
Academic refereed journal articles and abstracts primarily accessed through the University library databases (eg. CCOHS, Medline) should be consulted. It is important to try to look at the most ‘up to date’ authoritative sources. It may be necessary to search other internet sites, for example, government sponsored OHS sites.

ASSESSMENT SHEET FOR SEMINAR PRESENTATION
Name of Peer Assessor: Date and time
Group being assessed: Topic:
1. Introduction
Objectives of the seminar are clearly explained. A brief background on the nature of the chemical and typical sources of exposure is provided.
( / 3 mark)
2. Scope and depth of literature review on the relationship between exposure to the chemical and harm.
There is evidence that research of the topic has been rigorous in both depth and breadth of coverage. There is evidence of researching human and animal studies – that are as recent as possible. Clear arguments put forward to develop the dose-effect and dose-response relations.
( / 6 marks)
3. Use of the literature to develop an argument for identifying the exposure level representing the threshold of harm, and discussion of the derived threshold in relation to the OEL for the chemical.
There is evidence of using the dose-effect and dose-response information to identify the threshold of harm and that the current OEL for the substance has been correctly identified and considered in relation to the identified threshold for harm.
( / 8 marks)
4. General organisation, conclusions and referencing
Content is presented in an organised and rational way, and is completed within the 20 minute timeframe. Conclusions are appropriate.
