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
  • 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...

Some average daily intakes for long term exposures to dioxins:

  Daily intake (pg I-TEQ per kg body weight per day) See question
a This is the estimated human long term intake corresponding to the “Least Observed Adverse Effect Level” for the most sensitive adverse responses reported in experimental animals.
Adults in industrialized countries 1-3 2.1.2& 6.1.1
Breast fed babies Tens to hundreds of times more than adults 2.1.4
Rice oil contamination with PCBs in Japan (over 1 month) 154 000 2.2.1
Tolerable Daily Intake,TDI (over a life time) 1-4 6.3.1
Calculated LOAEL for long term exposure 14-37 6.3.1
