Search for properties hazardous to health and the environment

How hazardous is your substance? To assess whether a substance is hazardous, you can search the database PRIO. When assessing the hazard of a chemical, it is the inherent properties of the substance that are important, for example whether the substance is toxic, allergenic, or difficult to degrade. You can find out if the substance has any hazardous environmental and health properties and if the substance is covered by PRIO's criteria.

In the Standard Search, you can search by chemical name, CAS Number or EC Number. The Batch Search allows you to search on multiple CAS Numbers or EC Numbers at the same time. In addition to searching on individual substances, the Advanced Search allows you also to search on hazardous properties for health and the environment, on priority level, subject groups, occurrence in materials, product types or references. It is also possible to combine different search parameters.
