The Screening database was a database administered by IVL Swedish Environmental Institute on behalf of the Swedish Environmental Protection Agency. The database contained screening data of environmental pollutants from the national environmental monitoring program for the years 1849 - 2016. The screening database at IVL Swedish Environmental Institute is no longer updated. The Swedish Geological Survey (SGU) is by the Swedish Environmental Protection Agency commissioned as new national data host for environmental pollutants. The commissioning of a new environmental pollutant database is planned for 2022. In the new environmental pollutant database, all environmental monitoring data from screening of environmental pollutants , environmental pollutants in biota and metals and organic environmental pollutants in sediments will be available. Convention on Long Range Transboundary Air Pollution (CLRTAP) is the UN air transport Convention on Long-Range Transboundary Air Pollution. The convention covers 8 protocols, of which the POPs protocol, to which PRIO has referred, regulates the use of persistent organic pollutants (POPs). The POPs protocol within CLRTAP is no longer updated. The work of regulating transboundary POPs continues now globally within the Stockholm Convention.
All companies that manufacture or import a chemical product to Sweden must report the product's content to the Products Register. Data from the Products Register presented in PRIO provides information on the use of chemicals for chemical products. The information displayed in PRIO is non-confidential. For certain substances in PRIO there is information on: Product type that indicates which different types of chemical products the relevant substance is included in and what their function is. It is thus not a description of the function of the substance itself. How many of these are available to consumers . How large volumes of the substance are handled (tons). Read more about data from the Swedish Chemicals Agency's Products Register .

N-Class was a database developed by the Nordic Council of Ministers in collaboration with the European Chemicals Bureau (ECB). The database contained substances discussed in the Commission's Working Group on the Classification and Labelling of Dangerous Substances. The database described fire, health and environmental hazard classifications for substances listed in Annex 1 to Council Directive 67/548 / EEC on the classification and labelling of dangerous substances. In addition, there are substance specific data that formed the basis of the assessment made by the Commission's working groups. These data primarily concern environmental effects. The database is no longer in use, and the substances in PRIO that previously only had a reference to N-Class have been reviewed and updated with a reference to the CLP Regulation.
PRIO has been around since 2004 and has now undergone a major update in terms of usability and functionality. New criteria have been added and the database now contains twice as many subjects. Here you can read more about what is new in PRIO .
