Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Toxicity studies on soil organisms covering invertebrates, micro-organisms and plants have been carried out on the registered substance. The soil toxicity data have been used in the chemical safety assessment to establish PNECsoil.

The observed LC50 from the acute earthworm test (OECD 207) was 127.8 mg/kg soil dw. Chronic or long-term toxicity testing on soil microorganisms (OECD 216) and terrestrial plants (OECD 208 with six species, two monocotyledonous and four dicoyledonous) gave respectively a NOEC of ≥500 mg/kg soil dw and EC10 of 89.3 mg/kg soil dw (tomato, most sensitive species). According to ECHA guidance (Chapter R.7c, section R. where data from chronic or long-term tests are available, they should be used in preference to short-term tests to derive the PNEC. Since two long-term NOECs/EC10s are available, the PNEC has been derived from the lowest long-term result of the two trophic levels using, in accordance with ECHA Table R.10-10, an assessment factor of 50 to give a PNECsoil of 1.786 mg/kg soil dw. This value leads to PECsoil/PNEC soil < 1.

Given that the outcome of the chemical safety assessment demonstrates safe use of the substance to the terrestrial compartment, additional long-term testing is not considered to be necessary.
