 Averaging time (AT). The AT for carcinogenic effects of the contaminants
should be 70 years. This is the period (represented in days) over which the exposure
is averaged. This is referred to as the Lifetime Average Daily Intake. The averaging
time for exposures to noncarcinogens is the exposure duration (in days).
The product of this section is a numerical estimate (a range or single point) of
the average daily intake (dose) of a contaminant for each species consumed for each
potentially exposed receptor. This information should be presented in tabular
format.
