Key value for chemical safety assessment

Additional information

According to chapter R16 of the Guidance on information requirements and chemical safety assessment published by ECHA (2012), a substance can be assessed in a first step based on classification on the basis of mammalian toxicity data whether it has a potential to cause toxic effects if accumulated in higher organisms. For substances that are 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, secondary poisoning is a relevant route of exposure.

As oil shale thermal processing residue is not classified as toxic or harmful, the substance is not considered to cause toxic effects in predators. Additionally, the substance has only a low potential for bioaccumulation. In conclusion, oil shale thermal processing residue is considered to cause low hazard to predators. Thus, a study with birds is not needed due to animal welfare reasons.
