The William D. Wagner Award, established in 2003, is presented annually to a person in the field of national and international worker health and safety who is an outstanding example of commitment and dedication to the creation and dissemination of occupational exposure values (OEVs).
The 2026 William D. Wagner Award recipient is Claude Viau, D.Sc.
Claude Viau is a retired professor of toxicology in the Department of Environmental and Occupation Health of the School of Public Health at University of Montreal. He obtained a Bachelor Degree in Chemistry at McGill University, a Master in Analytical Chemistry at University of Montreal and a Master and a Doctorate Degrees in Medical Sciences at UCLouvain in Brussels. With the famous Professor Robert Lauwerys, one of the international pillars of Biological Monitoring, as a supervisor, the pathway forward to his career in industrial toxicology was evident.
Professor Viau joined the Department of Environmental and Occupational Health in 1987. He lectured in Environmental and Industrial Toxicology and conducted research mainly on the toxicokinetics of substances such as polycyclic aromatic hydrocarbons to better understand the fate of these contaminants and make a sound use of their metabolites as biomarkers of exposure. He published over 100 scientific articles in toxicology. He chaired the University of Montreal Public Health Research Institute between 2010 and 2014.
Viau chaired the Scientific Committee in Occupational Toxicology of the International Commission on Occupational Health between 2003 and 2009. He has been a member of the ACGIH Biological Exposure Committee from 2003 to 2023. From 2014 to 2017, he chaired the Scientific Expert Committee on Occupational Exposure Limit Values of the French Agency for Food, Environmental and Occupational Health & Safety as well as their Working Group on Biological Exposure Indices from 2010 to 2020.
