Key value for chemical safety assessment
Additional information
The toxicity of 4 -Nitrophenol on higher plants has been extensively reviewed by international groups of experts, i.e. BUA report No.75 (1992) and IPCS CICAD (2000). In studies according to the OECD Guideline 208 the 14 -day EC50 values for reduced fresh weight of grown shoots, after incubation of seeds with different test concentrations, were in the range of 35 -260 mg/L (Ballhorn et al. 1984, Marquart et al. 1984; cited from the IPCS CICAD 2000). Overall, turnip (Brassica rapa) proved to be the more sensitive species than oat (Avena sativa).
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.
