Technical Basis
A review of available sources did not identify exposure limits or acute toxicity data for lithium chromate. However, exposure limits for chromates were evaluated for TEEL development (CASRN: 1333-82-0), including TLV-TWA, TLV-STEL, PEL-STEL and IDLH (1990). Data sources were selected according to the hierarchy listed in Table 3.1. The IDLH was selected as the TEEL-3. The TLV-STEL was selected as the TEEL-1. A compound adjustment factor was applied to these exposure limits (Section 3.2.2). The TEEL-2 values were derived according to Table 3.5
• TEEL-1 = MW-adjusted TLV-STEL (chromic acid and chromates, as CrO3; CASRN:7440-47-3); 0.0005 mg/m³)
• TEEL-2 = TEEL-2/6
• TEEL-3 = MW-adjusted IDLH (1990, chromic acid and chromates, as CrO3; CASRN: 7440-47-3, 30 mg/m³)
This review generated TEEL-3 and TEEL-2 values consistent with Rev. 29A. The Rev. 29A TEEL-1 basis was a TLV-TWA for chromates, while the current basis is a higher priority source TLV-STEL for chromates (STEL > TWA).
