JUSTIFICATION FOR DATA WAIVING
In accordance with column 2 of REACH Annex IX, the biodegradation studies in water and sediment (simulation tests) do not need to be conducted since there is no need to investigate further the degradation of the substance and its degradation products. Sodium chlorite is a strong oxidizing agent and under proper reducing conditions is readily reduced to chloride, and to a lesser extent, chlorate. In strong acidic conditions, chlorite can change into chlorine dioxide (from pg. 11, USEPA/OPPTS; Reregistration Eligibility Decision (RED) for Chlorine Dioxide and Sodium Chlorite (Case 4023) p.1 (August 2006) EPA-HQ-OPP-2006-0328-0022/EPA 738-R-06-007.
