Substances in materials

Using the Search function in PRIO, you can identify what substances may be of relevance for a certain material. Articles are made up of one or several materials, and different materials are associated to various chemical substances. It may be substances that the article or material is made of, or additives or other substances that are used during the manufacturing process and appear as residues in the final product.

Material categories

In PRIO, the materials are categorised in 10 main categories correspond to the categories that will be used in the SCIP database External link, opens in new window. (Substances of Concern In Articles as such or in complex objects (Products)). The SCIP database is established by the European Chemicals Agency (ECHA) under the Waste Framework Directive and will contain information on particularly hazardous substances in articles. The main material categories in PRIO are further divided into subcategories which are not necessarily harmonized with the subcategories in the SCIP database. PRIO further includes an additional main category (Chemical product, material related) which is not used in the SCIP database.

The information on substances and their potential occurrence in materials is obtained mainly from public accessible sources. The sources include the government assignment on mapping hazardous chemical substances 2017–2020, Reach registrations and other databases. The information is divided into two levels of reliability (Occurrence in materials and Indicated presence in materials) to illustrate whether the information has been reviewed at a substance level or whether it is mainly based on an overall screening level (the reliability setting is based on an assessment by the Swedish Chemicals Agency). The information in the database on substances in materials is provided primarily from more reviewed data and secondarily at the screening level in cases where more reviewed data is not available. The Swedish Chemicals Agency will update the database on a regular basis.

Occurence in materials:

  1. the substance is included in the information sources used by the Swedish Chemicals Agency, and the information has been reviewed at a substance level.

Indicated presence in materials:

  1. the substance is included in the information sources used by the Swedish Chemicals Agency , and the information is mainly viewed at an overall screening level, or
  2. the substance has been detected in non-target screening studies.
