Technical Basis
A review of available sources did not identify exposure limits, acute toxicity data, or health hazard ratings for magnesium carbonate hydroxide. The PNOS TLV-TWA was selected as the TEEL-1 basis (Section 3.5.2). TEEL-3 and TEEL-2 values were derived according to Table 3.5.
• PAC-1 = TEEL-1 = TLV-TWA (PNOS, 10 mg/m3) x 3
• PAC-2 = TEEL-2 = TEEL-1 x 11
• PAC-3 = TEEL-3 = TEEL-2 x 6
This review generated PAC values consistent with Rev. 29A*.
