Description of key information

Study scientifically unjustified: According to Section 9.2.1.4, Annex IX of REACH, a simulation test on the degradation of Dust, steelmaking in aquatic sediments is required. However, such a study is not applicable to this material for the following reasons: Since Dust, steelmaking is an inorganic substance, it does not undergo biodegradation i.e. microbial degradation to carbon dioxide and water, since it does not contain any carbon or hydrogen atoms in its chemical formula. This material will be degraded in environment by means other then biodegradation. Therefore, the simulation test on the degradation of  in aquatic sediments is scientifically unjustified.
