Technical Basis
A review of available sources identified the following: acute toxicity data (LD50, LDLo) for dihydrogen hexachloroplatinate and TWA exposure limits for soluble platinum (CASRN: 7440-06-4, PEL, REL, TLV). Data sources were selected according to the hierarchy listed in Table 3.1. Toxicity data were selected according to type of exposure, species, and route according to the hierarchies stated in Sections 3.3.1, 3.3.2, and evaluated using factors in Tables 3.2, 3.3, and 3.4. The most preferred species toxicity data, a rat intravenous LD50, was selected as the TEEL-3 basis. The TEEL-2 value were derived according to Table 3.5. The TLV-TWA for soluble platinum was selected as the TEEL-1 basis and a compound adjustment factor was applied (Section 3.2.2).
• TEEL-1 = MW-adjusted TLV-TWA (soluble platinum, CASRN: 7440-06-4) x 3
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat intravenous LD50 (49 mg/kg)
This review generated TEEL values that are consistent with Rev. 29A*.
