Additional information
This study is read across to Phenol, isopropylated, phosphate (3:1); CAS No 68937-41-7; EC No 273-066-3.
The long-term effects on nitrogen transformation activity of soil microorganisms were minimal at concentrations 10, 32, 100, and 318 mg/kg dry soil. There was an observed effect of the substance on nitrogen transformation activity of soil microorganisms at concentration level 1010 mg/kg dry soil. After 28 days of exposure, the mean nitrate concentration in soil treated at 10, 32, 100, 318, and 1010 mg/kg dry soil exhibited a -1%, 1%, 0%, 2%, and 23% reduction in nitrate formation, respectively, compared to the controls. The EC10 was calculated to be 582.7 mg/L using linear interpolation between concentrations 318 and 1010 mg/L. The EC25 and EC50 were estimated to be >1010 mg/L, the highest concentration tested.
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.
