Technical Basis
A review of available sources identified acute toxicity data (rat oral LD50). Data sources were selected according to the hierarchy listed in Table 3.1. Toxicity data were evaluated using factors in Tables 3.2, 3.3, and 3.4. The lowest dose rat oral LD50 (225 mg/kg) source was not reported, therefore the other available dose (322 mg/kg) was selected as the TEEL-3 basis (Section 3.3.1). 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 = Rat oral LD50 (322 mg/kg)
This review generated TEEL values inconsistent with Rev. 29A. The Rev. 29A TEELs were molecular weight adjusted cadmium AEGLs; per Section 3.2.2, compound adjustment factors are not applied to AEGLs. Instead, the current TEEL-3 basis is a rat oral LD50, and TEEL-2/TEEL-1 values were derived according to Table 3.5.
