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
EC50 (28 d) >1000 mg test substance/L (nominal) based on nitrogen transformation rate (OECD 216)
Key value for chemical safety assessment
Additional information
One experimental study is available investigating the potential effects of Single Wall Carbon Nanotubes on nitrogen transformation of terrestrial microorganisms. The study was performed according to OECD guideline 216 under GLP conditions. A clay loam textured soil was exposed for 28 d to concentrations of 0 mg and 1000 mg test substance/kg dry weight soil. Young alfalfa powder was added to the soil (5 g/kg dry weight soil) to stimulate nitrogen transformation. The test substance caused no adverse effects (OECD 216) on the soil nitrogen transformation (based on the nitrate formation rate) in the tested concentration at the end of the 28 d incubation period. The EC50 (28 d) was therefore reported as > 1000 mg test substance/kg soil dw.
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.
