Technical Basis
A review of available sources did not identify toxicity data or exposure limits for neodymium bromide. Analysts evaluated GHS health hazards reported for this chemical (H315 and H319, Category 2; H335, Category 3), which indicate a mid-level health hazard. Considering this, analysts assumed an HHR=2 as the TEEL-3 basis (Section 3.4.5). TEEL-2 and TEEL-1 values were derived according to Table 3.5.
• PAC-1 = TEEL-1 = TEEL-2/11
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = HHR=2
This review generated TEEL values inconsistent with Rev. 29A. The Rev. 29A TEEL bases were the MW-adjusted AEGLs for bromine (CASRN: 7726-95-6), which is a physically dissimilar chemical. The current TEEL-3 basis is an assumed HHR=2, from analysis of GHS health hazard statements, from which TEEL-2 and TEEL-1 were derived (Table 3.5).
