2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is the reference chemical to which the toxicity of other dioxins and DLCs are compared. TCDD is the most toxic DLC known. Other dioxins and DLCs are assigned a scaling factor, or TEF, in comparison to TCDD. TCDD has a TEF of 1.0. Sometimes PCB 126 is also used as a reference chemical, with a TEF of 0.1.
For example, TeF 6 slowly hydrolyzes to Te(OH) 6: TeF 6 + 6 H 2 O → Te(OH) 6 + 6 HF. Treatment of tellurium hexafluoride with tetramethylammonium fluoride (Me 4 NF) gives, sequentially, the hepta- and octafluorides: TeF 6 + Me 4 NF → Me 4 NTeF 7 Me 4 NTeF 7 + Me 4 NF → (Me 4 N) 2 TeF 8
Specific dynamic action (SDA), also known as thermic effect of food (TEF) or dietary induced thermogenesis (DIT), is the amount of energy expenditure above the basal metabolic rate due to the cost of processing food for use and storage. [1]
