Toxic equivalency factor - Wikipedia
With the TEFs, the toxicity of a mixture of dioxins and dioxin-like compounds can be expressed in a single number – the toxic equivalency (TEQ). It is a single figure resulting from the product of …
Polychlorinated dibenzodioxins and –furans (PCDD/Fs, commonly known as dioxins) and polychlorinated biphenyls (PCBs) are a group of toxic and persistent chemicals whose …
Toxic Equivalents Scheme (TEFs & TEQs) - GreenFacts
The “Toxic Equivalent” (TEQ) scheme weighs the toxicity of the less toxic compounds as fractions of the toxicity of the most toxic TCDD. Each compound is attributed a specific “Toxic …
Data Tables - Dioxins and Dioxin-like Compounds in the Food …
The target concentration of 0.9 pg I-TEQ/g milk lipid was set as an objective to be achieved; if the TDI exceeds 10 pg I-TEQ/kg body weight (excluding PCBs) action should be taken to reduce …
Dioxin Data Report | TEQ's Toxic Equivalency Factors
In your report, you will find a concentration for all 2,3,7,8- congeners for dibenzo(p)dioixn (7) and dibenzofuran (10) expressed in units of ng/kg (nanograms per kilogram, parts per trillion) or …
The TEQ calculation passed both sensitivity analyses and the calculated value of 77.37 pg/g fat is therefore appropriate to use in the health evaluation. Health assessors are encouraged to
Toxic Equivalency Factor - an overview | ScienceDirect Topics
The relationship between the structure of individual PCDD, PCDF and PCB congeners and their toxicity is the basis of toxicity equivalency factors (TEFs) and the toxic equivalency (TEQ) …
Total TEQ intake in 2015 was estimated to be 40 pg TEQ/day (i.e. 0.53 pg/kg bw/day using 76 kg bw) and intake in Sweden was also estimated to be halved from 2000 (Livsmedelverket 2017). …
Summary of WHO 1998 and WHO 2005 TEF Values | Download …
The TEQ values (pg g − 1 ) of the 17 PCDD/F and 12 dl-PCB congeners were calculated based on their Toxic Equivalency Factors (TEFs) derived from the 2005 World Health Organization …
PCDD, present at the concentration [S] that is half as toxic as 2,3,7,8-tetraCDD is con-verted to TEQ as follows: TEQ = 0.5 [S]. The TEQ for a sample containing 20 pg 2,3,4,7,8-penta CDF/g …
