1. Column 1 is the laboratory sample identification number.

2. Column 2 is the site sampling identifier with site number, sample location and depth in metres. For example ‘6A0.1’ is site 6, sample location A, sampling depth 0.1 m (core from 0.05 to 0.15 m). Sampling depth 0.3 m is similarly a core from 0.25 to 0.35 m.

3. Column 3 identifies the sampling area as follows: AD = antisapstain dip or spray; BD = boric dip or spray; ST = sorting table; Store/mix = chemical storage or mixing area.

4. Columns 4 and 5 give PCP and TCP concentrations.

5. Columns 6 and 7 give dioxin TEQ values (for the I-TEF system) based on the OCDD screen and full congener analyses, respectively.

6. Columns 8 and 9 give dioxin TEQ values (for the WHO (1998) TEF system) based on the OCDD screen and full congener analyses respectively. OCDD screen TEQ values include 1,2,3,4,6,7,8-HpCDD as well as OCDD. Where a full congener analysis was conducted the TEQ values recorded under OCCD screen are those for 1,2,3,4,6,7,8-HpCDD and OCDD from the full congener results.

7. TEQ values include the detection limit value for those congeners not detected.

8. Some UCL values are at > 95% confidence limit depending on data distribution.
