The toxicity to soil macroorganisms of the test item was tested in an acute toxicity test to earthworm. The test was carried out in accordance with the OECD Guideline 207 (Earthworm, Acute Toxicity Tests).
Shot-term toxicity to invertebrates
The acute toxicity of KMPS triple salt to
Eisenia foetida was determined in a dose-response 14-day test according
to the OECD guideline 207. After 14 days of exposure to treated
artificial soil the LC50 for earthworms was determined to be >1000 mg
KMPS triple salt/mg soil. No effects on biomass or behaviour were
LC0 = 1000 mg/kg soil
LC50 > 1000 mg/kg soil
Long term toxicity to invertebrates
In accordance to section 9.4.4 of Annex X,
long-term toxicity to invertebrates, does not need to be conducted if
direct and indirect exposure of the soil compartment is unlikely. An
acute toxicity test in Eisenia fetida was done with KMPS triple salt. Up
to a test concentration of 1000 mg/L no toxic 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 long-term testing is considered to be
scientifically not justified.
