- JUSTIFICATION FOR DATA WAIVING
It is not expected that sediment compartment is a concern for Slimes and Sludges, blast furnace and steelmaking. Due to the properties of the substance a hazard to sediment organisms is assumed to be low. Acute and chronic study results show that the substance has only a low toxicity for mammals and aquatic organisms. Hence, considering low concentrations in the aquatic environment and the most likely harmlessness of Slimes and Sludges, blast furnace and steelmaking for sediment organisms, no exposure to sediment is expected (direct and indirect exposure of the sediment compartment is unlikely) and no long-term toxicity data for sediment organisms should be generated.
Further, due to the natural occurrence of Slimes and Sludges, blast furnace and steelmaking constituents in the environment, it is expected that Slimes and Sludges, blast furnace and steelmaking would not be toxic to sediment organisms.
