Daily Dioxin Intakes
The long-term intake of dioxins can be expressed in:
- picogram I-TEQ per kilogram of body weight per day (pg I-TEQ/kg body weight per day, pg I-TEQ/kg bw.day)
- picogram I-TEQ per person per day (pg I-TEQ/person/day); to convert from one unit to the other, it is generally assumed that an adult person weighs 60 kg.
In these units, I-TEQ stands for International Toxicity Equivalent (and is sometimes omitted in writing).More...
The uptake of dioxins by living organisms leads to accumulation in the body, resulting in a body burden.More...
