Abstract

During scoping of this assessment’s TSCA related uses, exposures and hazards were identified for Hexabromocyclododecane (HBCD; CASRN 25637-99-4), 1,2,5,6,9,10-Hexabromocyclododecane (1,2,5,6,9,10-HBCD; CASRN 3194-55-6), and 1,2,5,6-Tetrabromocyclooctane (CASRN 3194-57-8). This Problem Formulation Assessment describes the TSCA related uses that were evaluated for inclusion and exclusion in this assessment. This problem formulation includes the conceptual model and the analysis plan for evaluating those uses for HBCD.
