Human health risk assessments use modeling and data to predict the exposure of operators, workers, residents, and bystanders to chemicals in products. Exponent has extensive experience using the regulatory models required for risk assessment for plant protection products, biocides, and chemicals subject to Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) legislation in the EU and the U.K.

How can you assess the human health exposure of your products to support regulatory compliance?

We support clients in the chemicals industry throughout the regulatory process from preliminary risk assessment and data generation to submission and post-submission support. Our exposure specialists work closely with our toxicologists to perform thorough human health risk assessments and help you make the best use of your data. We keep up with the constantly changing regulations, study guidelines, and data requirements to overcome future challenges that may impact your products. 

Plant protection products

Exponent consultants have helped develop operator (non-dietary) exposure assessment models used by regulatory authorities and continue to advise in the development of new models. We have extensive experience with the current European Food Safety Authority online model as well as national models used by individual Member States. Our expertise includes monitoring higher-tier exposure and toxicology studies, which may be required for more complex product assessments.


Leveraging extensive experience in tiered and refined human health risk assessments, we support active substance and product authorizations for all biocidal product types. We have in-depth knowledge of risk assessment scenarios, exposure modeling tools (e.g., ConsExpo), and product-type specific guidance documents by the Human Exposure Expert Group and the Health Exposure Ad-hoc Working Group. In addition, our consultants assist in the construction of biocidal product families (considering similarity of risk); identify and evaluate substances of concern; and perform livestock, companion animal, and consumer dietary risk assessments where necessary.
