PRIO is updated with the 2022 reported Products register data. The Swedish Chemicals Agency's Products register contains information on the use of substances in chemical products manufactured in or importeted to Sweden.
Two new criteria have been introduced in PRIO and three existing criteria have been updated. The new and updated criteria in PRIO are a consequence of the four new hazard classes being adopted and implemented in the CLP regulation. The changes mean that more substances with environmental and health hazards are covered by the criteria in PRIO and several new substances have been added to the database. Two new criteria PMT/vPvM - substances that are persistent, mobile and toxic or very persistent and very mobile at the phase-out substance level Potential endocrine disrupting – substances that are suspected endocrine disruptors for human health or the environment at the priority risk-reduction substance level Changes to three existing criteria PBT/vPvB – substances that are persistent, bioaccumulative and toxic or very persistent and very bioaccumulative at the phase-out substance level Potential PBT/vPvB - substances that are suspected to be persistent, bioaccumulative and toxic or very persistent and very bioaccumulative at the priority risk-reduction substance level Endocrine disrupting – substances that are endocrine disruptors for human health or the environment at the phase-out substance level Read more about the PRIO criteria for phase-out substances and priority risk-reduction substances

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 The screening database at IVL Swedish Environmental Institute is no longer updated.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 .
