<unk>  <unk>  estimates the amount per unit body weight of a potentially harmful substance or contaminant in food or water that can be ingested over a lifetime without risk of adverse health effects.<unk>  is generally preceded by "provisional" to indicate insufficient data exists, increasing uncertainty. The term<unk>  should be reserved for when there is a well-established and internationally accepted tolerance, backed by sound and uncontested data. Although similar in concept to<unk>  daily intake (TDI), which is of the same derivation of acceptable daily intakes (ADIs),<unk>  accounts for contaminants that do not clear the body quickly and may accumulate within the body over a period of time. An example is heavy metals such as arsenic, cadmium, lead, and mercury. The concept of<unk>  takes into account daily variations in human consumption patterns.
