Tarah Hagen is a director and senior consultant at ToxConsult Pty Ltd providing environmental toxicology and risk assessment services to a broad range of industries and government bodies.

She has an honours degree in ecotoxicology, a primary degree in Applied Science (Biological Sciences) and a Masters degree in Environmental Toxicology and Pollution Monitoring. She is also one of only a few toxicologists in Australia certified as a Diplomate of the American Board of Toxicology.

She has 10 years experience in conducting screening and detailed human health and ecological risk assessments for a variety of industries and government. Included are contaminated land and water, consumer goods, food, and industrial emissions.

Ms Hagen has considerable experience in sourcing, collating and interpreting toxicological hazard information. She creates chemical toxicology profiles in which hazards and toxicity reference values are carefully described thereby ensuring the information is fit for the purpose of the risk assessment. She is also adept in building exposure scenarios for human and environmental risk assessment.

She has considerable expertise in classifying mineral ores and concentrates as to their environmental hazard for transport purposes. She has been involved in several complicated risk assessments dealing with lead contamination, and is adept at using and applying the results of the US EPA Integrated Exposure Uptake and Biokinetic (IEUBK) Model for lead. She has also applied this knowledge in helping derive recommendations for ambient air license limits for industries handling concentrates of lead ores, as well providing advice for recommended changes to the occupational exposure limit for lead.

Tarah has also been involved with various publications reviewing the toxicity of engineered nanomaterials, in relation to work and public health and safety, the latter particularly concerning their use as food additives and migration from food packaging into foods.

She has also been involved in several complex human health risk assessments for occupational and public exposure to per- and poly-fluorinated alkylated substances (PFASs). This work has included reviewing and interpreting toxicological information for consideration of appropriate toxicity reference values, delineating potential exposure pathways, as well as estimating and interpreting internal exposure metrics with respect to human health.

Ms Hagen has a good understanding and experience of ecotoxicity testing which has been used to derive trigger values for contaminants in water using probabilistic species sensitivity distribution methodology.

She regularly presents at scientific conferences, and is a registered member and secretary of the Australasian College of Toxicology and Risk Assessment (ACTRA).
