Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

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. Therefore, no tests on soil macroorganisms are provided.

Key value for chemical safety assessment

Additional information

In a 14-day acute toxicity study with Eisenia fetida no effects were observed up to 1000 mg test item/kg soil dw (BASF 1996). In a chronic study with Eisenia fetida a NOEC of 305.0 mg test item/kg soil dry weight was determined (BASF 2012). Under the very conservative assumption that these adverse effects are caused by the pentanolic fraction only, a NOEC of 106.75 mg /kg soil dry weight could be extrapolated for the pentanols. Nevertheless, we would expect that a chronic study with Eisenia fetida on pentanol would result in a much higher NOEC value.However, this NOEC based on worst-case assumptions has been used for the PNECsoil derivation.
