:Slovak term: [[Slovenský termín]]
# Estimated maximum amount of an agent, expressed on a body mass basis, to which individuals in a (sub)population may be exposed daily over their lifetimes without appreciable health risk (WHO 2004).

Acronym: TDI

==Explanation==
The TDI is an estimate of the amount of a substance in food and drinking-water, expressed
on a body weight basis (mg/kg or mg/kg of body weight), that can be ingested over a
lifetime without appreciable health risk (WHO 2006).

It should be noted that the terms [[ADI]] and TDI are used in different context and are not
synonymous.

==Example==
As it relates to administration in drinking-water, for chemicals that give rise to such toxic
effects, a tolerable daily intake should be derived as follows, using the most sensitive
end-point in the most relevant study (WHO 2006):

TDI =(NOAEL or LOAEL) / UF

where: 
* NOAEL = no-observed-adverse-effect level
* LOAEL = lowest-observed-adverse-effect level
* UF = uncertainty factor
