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