Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The lowest toxicity values (corrected, where appropriate, for standardised organic matter content of 3.4% and a conversion factor of 1.13 for transforming results from a dry weight to wet weight basis) are as follows: Acute toxicity to earthworms 14 d LC50= 26 mg/kg dw= 23 mg/kg ww (Eisenia foetida) Chronic toxicity to57 d NOECrepro = 3.3 mg/kg dw= 2.9 mg/kg ww earthworms (Eisenia foetida) Toxicity to plants NOECemergence= 19 mg/kg dw= 17 mg/kg ww (Mustard, Sinapis alba) Toxicity to soil micro-organisms 28 d NOEC≥ 128 mg/kg ww (nitrifying micro-organisms in sandy loam soil) The availability of a data set that includes acceptable results from three long-term tests with species from at least three trophic levels, means that it is possible to derive a PNECsoil from the test data by applying an assessment factor of 10 to the lowest chronic NOEC. The resultant PNECsoil is 3.3/10 = 0.33 mg/kg soil dry weight.
