Description of key information

The acute toxicity to birds of KMPS triple salt was investigated in an Avian dietary toxicity test according to the OECD Guideline 205.

Key value for chemical safety assessment

Additional information

Toxicity to birds

The dietary LC50 study for Northern Bobwhite exposed to KMPS triple salt was terminated after 1 day of exposure. When dissolved in deionised water to prepare dosing solutions, KMPS triple salt creates an acidic solution, below the normal pH range of the digestive tract of birds. Animal welfare concern prohibited the dosing of an acidic solution that would be certain to cause acid burns in the upper digestive tract. Therefore, the dosing solutions were buffered prior dosing. Subsequent analysis revealed that with buffering KMPS triple salt could not be maintained in solutions. The study was therefore terminated.

Data Waiver: Toxicity to birds

In accordance to section 9.6.1, column 2 of Annex X, reproductive toxicity test to birds does not need to be conducted as a mammalian dataset is available (see toxicological studies) In addition direct and indirect exposure of the soil compartment is unlikely. The substance has no high potential to adsorb to soil and is not very persistent. According to the available information of the toxicity test to Eisenia fetida, no toxicity effect could be observed (LC50 > 1000 mg KMPS triple salt/ L). This result shows that KMPS triple salt has a very low acute toxicity to earthworms (IUCLID section 6.3.1). As there are no other indications of concern for the terrestrial compartment, further testing to terrestrial arthropods is considered to be scientifically not justified.
