Technical Basis
A review of available sources did not identify exposure limits or acute toxicity data for cobalt(II) tetraphenylporphyrin. Given this lack of information, the GHS health hazard ratings for tetraphenylporphyrin (C44H30N4, CASRN: 917-23-7) were evaluated; cited codes (H302, H312, H332) indicates it is Category 4 health hazard, approximately equivalent to an HHR=1. As such, an HHR=1 was assumed and selected as the TEEL-3 basis (Section 3.4.5, rat oral LD50 = 40000 mg/kg). TEEL-2 and TEEL-1 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = HHR=1
This review generated TEEL values consistent with Rev. 29A*.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = HHR=1
This review generated TEEL values consistent with Rev. 29A*.
