CRC CARE Workshop: Human Health Risk Assessment – the 'how to' Guide


Overview: The ‘how to’ guide

This two-day Human Health Risk Assessment (HHRA) workshop will provide attendees with an introduction to the HHRA process and will focus on the practical ‘how to’ aspects along with resources for further education. Secrets within the ‘black-boxes’ of HHRA models will be revealed in this engaging and interactive workshop by leading attendees step-by-step through the HHRA process. The workshop will provide the skills for identifying and selecting the information to perform HHRAs. At the conclusion of the workshop, attendees will know how to apply risk assessment methodology to evaluate if chemical exposure or contaminated land, presents a significant risk of harm to human health.

To maximise the learning potential of the group, attendees are encouraged to participate in group exercises and share their knowledge and experience.

Day 1: Workshop topics will include:
  • Introduction: What is HHRA? What HHRA guidance exists?
  • Issue Identification: the importance of a conceptual site model, ‘source-pathway-receptor’ linkages
  • Exposure Assessment: exposure pathways; receptor identification; default/site-specific exposure assumptions; calculation of a dose; introduction to vapour modelling; exposure point concentrations
  • Physico-chemical parameters for HHRA
  • Toxicity Assessment: introduction to toxicology and toxicity information sources
  • Risk Characterisation: hazard quotients; hazard indices; increased lifetime cancer risks
  • Sensitivity and Uncertainty Analysis: why do this? How do we do this?
Day 2: Workshop topics will include:
  • Advanced toxicology concepts: background exposure; assessment of mutagenic compounds and early-life exposure; absence of information and route-to-route extrapolation
  • Introduction to blood lead modelling: lead toxicology overview; IEUBK model; adult lead model
  • Derivation of Site-Specific Target Levels
  • Comprehensive case study: participants will be required to complete a health risk assessment based on a fictitious case study in small groups using the skills and information obtained from Day 1 of the workshop.

Who should attend

The workshop is aimed at people who have no prior experience performing HHRAs but it is assumed that attendees will have some knowledge of the contaminated site industry. The workshop should be of interest to regulators, industry professionals and consultants who are required to perform, review and interpret HHRAs.

Please note that participants planning to attend Day 2 only, will ideally have some prior risk assessment experience and/or attended the CRC CARE HHRA workshop delivered in March 2017.

Attendees are required to bring a calculator, and Day 2 attendees are also required to bring computer
laptop or phone to access internet resources.


Belinda Goldsworthy, PhD, BSc, RACTRA

Human Health and Ecological Risk Assessor with Ramboll Environ Australia

Dr Belinda Goldsworthy has more than 15 years’ experience in the contaminated sites industry and specialises in human health risk assessments. She has extensive experience using both deterministic and probabilistic risk assessment exposure techniques to assess potential risks to human receptors for contaminated sites in Australia and internationally, including Malaysia, Singapore, India, Hong Kong, Oman, Japan, Indonesia and Pakistan. These risk assessments involved the use of current vapour intrusion assessment techniques and the derivation of site-specific target levels to guide remediation management decisions.

Belinda is approved by the NSW Environment Protection Authority to provide technical support to Accredited Contaminated Land Auditors for risk assessment projects, and is an accredited registrant of the Australian College of Toxicology and Risk Assessment.

Belinda has provided risk assessment and toxicology training to the Australian Department of Health, Department of Defence, environmental and health regulators, and industry colleagues. Her training techniques are aimed at engaging course attendees via the use of interactive lectures, group activities/discussions, pre- workshop reading materials, use of case studies, and multimedia and interactive materials.

Comments from participants of 2017 workshop

“Excellent workshop. Very engaging and knowledgeable in the area. Discussions were very valuable in learning other participants’ experience.”

“A much better understanding of risk assessment which I was looking for. Totally met my expectation. A worthwhile workshop, thanks!”

“I just wanted to say thank you for the CRC CARE Human Health Risk Assessment workshop you presented a few weeks back. I don’t have much experience in tier 2 assessments, but the presentation, notes and supporting docs you provided have all been excellent.”

“Great workshop by an expert presenter.”
