📊Methodology

OpenChemFacts provides aquatic ecotoxicity impacts for thousands of chemicals.

These impacts are calculated through the latest international consensus around USETOX model (cf. this article for more information).

OpenChemFacts platform is under construction and only provides hazard values (effect factor) as of now.

Once Fate Factors (FF) and Exposure Factors (XP) are introduced it will be possible to calculate risk values (characterization factors).
