Note:
The above population dietary exposures have been estimated using mean
concentrations for each food group and consumption data from the National
Food Survey.
Changes in the organisation of the TDS from 1981 onwards mean that
exposures from TDSs before 1981 and from 1981 onwards are not directly
comparable.4
For those years where no values are given, these elements were not
included in TDSs for metals and other elements.
n.d. not determined
*Dietary exposure estimates for selenium from the 1995
TDS are not directly comparable with those from other years as they are
based on analyses of composite samples of each food from all the towns in
the TDS rather than the upper bound mean concentrations of analyses of
each food group from each town
