Technical Basis
A review of available sources identified the following: acute toxicity data (TDLo, LD50) and exposure limits (TLV-TWA, IDLH) for soluble thallium compounds. Data sources were selected according to the hierarchy listed in Table 3.1. The IDLH (1990) was selected as the TEEL-3 basis and the TLV-TWA as the TEEL-1 basis; a compound adjustment factor was applied to these exposure limits (Section 3.2.2). The TEEL-2 value was derived according to Table 3.5.
• TEEL-1 = MW-adjusted TLV-TWA (soluble thallium, CASRN: 7440-28-0, 0.2 mg/m3) x 3
• TEEL-2 = TEEL-3/6
• TEEL-3 = MW-adjusted IDLH (1990, soluble thallium, CASRN: 7440-28-0, 20 mg/m3)
This review generated TEEL values consistent with Rev. 29A.
• TEEL-1 = MW-adjusted TLV-TWA (soluble thallium, CASRN: 7440-28-0, 0.2 mg/m3) x 3
• TEEL-2 = TEEL-3/6
• TEEL-3 = MW-adjusted IDLH (1990, soluble thallium, CASRN: 7440-28-0, 20 mg/m3)
This review generated TEEL values consistent with Rev. 29A.
