Data waiving in accordance with REACH Annex IX, 9.4, Column 2
Key value for chemical safety assessment
Additional information
Soil microorganism toxicity is highly unlikely: two reliable tests on STP microorganism toxicity are available, covering the sensitive endpoint of nitrification. Up to the highest tested concentration of 100 mg/L, no effect on nitrification could be observed (NOEC), while only a slight inhibition of 5% was observed in the activated sludge respiration inhibition test with prolonged incubation time (7 days). According to ECHA guidance document on IR and CSA R.7c, section R.7.11.5.3, under such circumstances an additional test on soil microbial activity is not necessary. Furthermore, in accordance with REACH Annex IX, 9.4, Column 2, direct or indirect exposure of the soil compartment is unlikely and the submission substance is readily biodegradable. Furthermore, the substance is not classified according to 67/548/EEC and regulation (EU) no. 286/2011. The substance does not have a potential to bioaccumulate nor is it considered as a PBT/vPvB substance. The EPM method may be applied to assess the hazard for soil organisms.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
