Faculty of Health and Medical Sciences

Len has worked in the field of public health, toxicology, and human health risk assessment for over 35 years, with 20 years in the SA Department of Health (Environmental Health Branch) and the balance in international environmental consulting firms and more recently at the University of Adelaide.

He has worked across a diverse range of public health areas including asthma and risk factors; site contamination including development of national Health-based Investigation Levels (HILs) (1990-2003); assessment and mitigation of environmental and occupational exposures associated with industrial facilities, processes and mining operations and toxicological assessments for policy development and regulatory review. As part of the assessments, he has been extensively involved in large scale community exposures, assessments, and risk communication, including Streaky Bay Area School (Aldrin, 1987-1997); Port Pirie Lead Program (1986-2006); site contamination at Hindmarsh (1987-1994); cadmium contamination at West Lakes and site contamination at Birkenhead (2003-2004).

He completed the health risk assessment for the new Royal Adelaide Hospital site (2010-2015) which was part of a multi-billion-dollar development. In collaboration with Dr Neville Robinson (CSIRO, Flinders University) Len developed an Australian non-steady state vapour intrusion model, originally published in 2001 and has extended this work with continuing research. In recent years he has been an expert witness in cases involving human exposures to hazardous substances and contributed to peer-review of large scale PFAS and vapour intrusion investigations. In 2018 Len was part of the Adelaide University team that commenced the review of the Workplace Exposure Standards (WES) for Safe Work Australia.

Len is a Member of the Royal Australian Chemical Institute (RACI) (Chartered Chemist); the Australasian College of Toxicology and Risk Assessment (ACTRA) and the Clean Air Society of Australia and New Zealand (CASANZ) and has been involved on various committees and training exercises with these associations. He has also contributed to training and presentations on toxicology and risk assessment to meetings of the Australian Contaminated Land Consultants’ Association (ACLCA) and the Australian Land and Groundwater Association (ALGA) and CASANZ.

He has provided technical public health and policy advice across government, research sectors and industry, nationally and internationally with extensive contacts throughout these sectors. Len currently undertakes research and teaching as a part-time Senior Research Fellow and at Adelaide Exposure Science and Health, School of Public Health, University of Adelaide. He is also Founder and Director of HealthRisk Services Pty Ltd, a consulting service across exposure science, public health toxicology and human health risk assessment and a Founder and Director of SwabFirst Pty Ltd, a technology start-up company that has developed a surface screening approach to illicit drug residues and nicotine.
