Technical Basis
A review of available sources did not identify exposure limits or acute toxicity data for calcium oxalate. Analysts evaluated GHS health hazards reported for this chemical (H302 and H312, Category 4), which indicate a mid-level 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 PAC values consistent with Rev. 29A*.
