EC number: 442-300-8
CAS number: -
The study does not need to be conducted, because direct or indrect exposure of the soil compartiment is unlikely.
The test substance is not supposed to
be directly applied to soil and an indirect exposure to soil via sewage
sludge transfer is unlikely since the substance is readily
biodegradable. For a substance being considered as „readily
biodegradable“, it can be assumed that it will be biodegraded within the
STP process and as a consequence a transfer to the soil compartment is
not expected. However, an acute toxicity test to the earthworm Eisenia
fetida in artificial soil has been conducted to investigate the effects
of the test substance to terrestrial organisms. After 14 days no
mortality at the tested limit concentration of 1000 mg test item/kg
artificial soil dry weight. The biomass of individual adults after 14
days amounted to 89.5% of the initial weight in the solvent control,
87.9% in the control and 88.8% at 1000 mg test item/kg artificial soil
dry weight. Therefore, the NOEC was regarded to be ≥ 1000 mg test
item/kg soil (dw). In conclusion, toxic effects of the test substance to
terrestrial athropods are not expected and a study on terrestrial
arthropods is not provided.
