In specific contract No 1 issued under the framework agreement OC/EFSA/MESE/2023/03, EFSA requested Open Analytics to extend and update the web application for non‐dietary exposure estimates (for operators, workers, residents and bystanders) related to the use of plant protection products. This online tool was amended with correction of several calculated values, an increase in the flexibility of the calculations, generation of different reports and an update of the Manual (as appropriate). This report discusses the implemented changes to the R‐package opex for calculating risks, generating reports and building the web application.
