Description of key information
Additional information
The toxicity for soil organisms (plants and microorganisms) of the read-across substance n-butyl phosphorothioc triamide (NBPT) was assessed on the basis of studies conducted with urea fertilizer containing the urease inhibitor. The most sensitive effect concentration stems from toxicity-testing with soil microorganisms resulting in an EC50 of 0.05 mg/kg dw soil (Bremner et al., 1986)
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.
