Description of key information

Adsorption and desorption behaviour of the cyclic constituent is not yet fully understood. Some tests regarding the terrestrial toxicity were required in the last submission of the dossier and they are under evaluation by ECHA.

Additional information

Adsorption and desorption behaviour of the cyclic constituent is not yet fully understood.

 

Once that process is complete, if it is confirmed that desorption from soil occurs in vitro for this constituent of the substance, then selected terrestrial ecotoxicity studies may be useful to refine the PNEC. Provisionally, test proposals are in place but these may be removed in a future update if irreversible binding to soil (identified by a lack of desorption from soil in the OECD 106 test) is definitively demonstrated. Any test(s) could be conducted on whole substance of known composition, representative of the supplied substance, or on a purified sample of the cyclic constituent, and this would be explored as part of test planning.

Some tests regarding the terrestrial toxicity were required in the last submission of the dossier and they are under evaluation by ECHA (see draft decision-ECHA comm. numb. TPE-D-2114321164-63-01/Don 15 March 2016).
