RIVM has developed a manual for ConsExpo Web. This web application has been developed for use by exposure experts and risk assessors to estimate exposure to chemical substances from various products under various exposure conditions. Exposure assessments provide necessary information for the evaluation of the safety of chemical substances in consumer products. ConsExpo Web is the successor to ConsExpo 4. Using ConsExpo Web, exposure experts and risk assessors from authorities, institutes and companies can assess consumer exposure in a transparent, standardized fashion. There is a wide variety of consumer products, ranging from cosmetics to cleaning products and pest control products. Their use (e.g. how much of the product is used and how frequently) also varies among consumers. ConsExpo Web provides a number of generally applicable exposure assessment models and a database of exposure factors. Together, the models and the database provide a basis on which exposure from a specific product can be estimated. This document provides an overview of ConsExpo Web, an explanation of the exposure and absorption models available in ConsExpo Web and guidance for the careful analysis of the exposure assessment. ConsExpo Web is available via rivm.nl/consexpo. After registration, the use of ConsExpo Web is free.
