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


Overview: The ‘how to’ guide

This one-day Human Health Risk Assessment (HHRA) Workshop will provide attendees with a ‘how to’ guide for performing contaminated site and chemical health risk assessments in accordance with Australian guidance. 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 necessary 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.

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.

Workshop topics covered 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
  • Introduction to toxicology
  • Toxicity assessment: toxicity information sources; age-dependent adjustment factors; background exposure
  • Risk characterisation: hazard quotients; hazard indices; increased lifetime cancer risks
  • Site-specific remediation/screening criteria: What are they? How do you derive them?
  • Sensitivity and uncertainty analysis: Why do this? How do we do this?

Workshop Participants are required to bring a calculator and will receive an information pack containing:

  • course notes, handouts and group activities
  • a USB drive containing relevant HHRA documents and guidance material
  • a list of suggested pre- and post-workshop reading material.


Belinda Goldsworthy, PhD, BSc, RACTRA

Senior Manager 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.
