Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Aquatic compartment:

Based on the results of a study conducted in accordance with OECD Guideline 211, the PNECwater value for the test material is based on the lowest long-term endpoint of 0.01 mg/L from a Daphnia magna reproduction study with DDAC. An assessment factor of 10 is used as there are long-term NOEC values for three trophic levels (fish, daphnia, algae). Therefore, the PNECwater is 0.001mg/L.

STP compartment:

Based on the results of a study conducted in accordance with OECD 209 (Respiration inhibition of activated sludge), the lowest 3 hour EC50 from the key study was 11.8 mg/L. The appropriate Assessment Factor taking into account one OECD 209 EC50 endpoint is 100. The PNECmicroorganisms is, therefore, 0.118 mg/L.

Soil compartment:

Based on the results of the key study, terrestrial plants were deemed to be the most sensitive group, based on the suppression of seedling growth, with the lowest growth related EC50of 283 mg/kg dry soil for mustard seedlings. An assessment factor of 100 was considered appropriate based on the fact that there were endpoints available for three trophic levels, including long-term endpoints for multiple groups of soil microflora and endpoints for three different higher terrestrial plants (reducing uncertainty over the range of response among the most sensitive group of organisms).

Oral compartment:

Due to the limited potential for bioaccumulation in fish, the risk of toxicity via the oral route (food chain) is not considered to be likely and no further assessment is necessary.

Conclusion on classification

Based on the results of the studies provided, the test material requires the following classification under CLP Regulation:

Signal word - Warning ;

H400: Very toxic to aquatic life.

H410: Very toxic to aquatic life with long lasting effects.
