Appendix 1

Notes on the tables:

1 A range of exposures is presented in these tables. The lower end of the range (the first result) assumes that results less than the limit of reporting = 0 and the upper end of the range (the second result) assumes that results less than the limit of reporting = limit of reporting. The limits of reporting are provided on page 12 of this report.

2 There were no results reported as less than the limit of reporting for copper and zinc, so only one dietary exposure estimate is provided.

3 1 µg = one millionth of 1 g.

4 Estimated dietary exposures are based on food consumption data from the 1995 National Nutrition Survey.

5 Tolerable limits for metal contaminants are listed in Table 8 in the supplementary information on ANZFA's website.
