Additional information
This information is not available. However, information concerning the toxicity of the substance to birds is not a mandatory requirement according to Annexes VII and VIII of Regulation (EC) No. 1907/2006. Furthermore, in Annex X it is stated that any need for testing should be carefully considered taking into account the mammalian dataset. UC-141 shows high bioaccumulation potential, neverthelesssecondary poisoning is a route of exposure primarily relevant for substances classified as Very Toxic (T+) or Toxic (T) or Harmful (Xn) with at least one of the risk phrases R48, R60, R61, R62, R63 or R64. SinceUC-141is not classified as toxic or harmful, the substance is not likely to cause toxic effects in predators. However, a PNEC oral has been calculated using mammalian data for the sake of completeness and considered for further risk assessment.
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.
