CAS number: 67774-74-7
The substance is readily biodegradable and
no hazard was identified for aquatic organisms (acute and long-term
studies available in fish, aquatic invertebrates and algae). One
short-term toxicity test on a soil macroorganism (nematods) is available
in which the low toxicity was confirmed (LC50 =7960 mg/kg soil dw). This
study was conducted according to ASTM E2172-01 guideline (2001). It was
considered valid and used for PNECsoil derivation in accordance with the
Guidance on information requirements and chemical safety assessment
Chapter R.10: Characterisation of dose [concentration]-response for
environment, and used in the risk assessment.
The chemical safety assessment indicates
that the risks in the soil are controlled (PNEC/PEC < 1). Therefore, at
this stage, in accordance with the Guidance on Information Requirements
and Chemical Safety Assessment Chapter R.7c: Endpoint specific guidance
and based on the available information on aquatic organisms and nematods
indicating very low toxicity, long-term studies on the effects of the
substance on soil macroorganisms except arthropods, terrestrial plants
and soil microorganisms are waived.
