Description of key information
It is not useful to derive a PNEC for potassium hydrogencarbonate for the following reasons: potassium as well as carbonate is ubiquitously present in the environment, occurring naturally in minerals, soils and sediments, natural waters (oceans, lakes, rivers), biota and human beings; potassium hydrogencarbonate does not accumulate in living organisms, secondary poisoning through the food chain is considered of no concern for birds.
Key value for chemical safety assessment
Additional information
According to REACH Annex X, 9.6.1, column 2, any need for testing of birds should be carefully considered taking into account the mammalian dataset that is available for potassium hydrogencarbonate. Further testing seems not useful as potassium hydrogencarbonate does not accumulate in living organisms, secondary poisoning through the food chain is considered of no concern for birds.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
