How PRIO relates to some regulation and to the classification list
The PRIO database contains both substances that are regulated and those that are not covered by any legislation. PRIO is not based on legislation but has to do with the substances' inherent health and environmental properties. Under Rules and regulations on our website you will find a large part of the legislation that applies to chemical products and chemical substances in articles. Please note that there is more legislation concerning chemical products and substances from other authorities, for example at the the Swedish Work Environment Authority, the Swedish Environmental Protection Agency, and the Swedish Civil Contingencies Agency.
