Description of key information
On a molecular weight scaled basis, the 1d EC50 would be 22.6 mg/kg soil dw. (10x 172.24) /76.13 =22.6 mg/kg soil dw
After fumigation of soils with CS2 the microbial metabolism of soil was seriously affected. At 10 mg CS2/kg the nitrification was completely inhibited.
Key value for chemical safety assessment
- Short-term EC50 for soil microorganisms:
- 22.6 mg/kg soil dw
- Long-term EC10 or NOEC for soil microorganisms:
- 0.95 mg/kg soil dw
Additional information
On a molecular weight scaled basis, the EC50 would be 22.6 mg/kg soil dw. (10x 172.24) /76.13 =22.6 mg/kg soil dw After fumigation of soils with CS2 the microbial metabolism of soil was seriously affected. At 10 mg CS2/kg the nitrification was completely inhibited.
The nitrification in three soil types was inhibited by CS2. The 5-d EC50 in Harps clay loam soil was 0.21 mg/kg soil dw and the 14-d EC50 was 2.1 mg/kg soil dw.
On a molecular weight scaled basis, the EC50 would be 4.75 mg/kg soil dw. (2.1 x 172.24) /76.13 =4.75 mg/kg soil dw(NOEC=0.95 mg/kg soil)
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.
