NOTES
1. PLACE, DATE AND EVENT NAME

1.4. Set it in MetaPlus Book Roman, if you own the typeface. Otherwise, keep the original typeface – Arial.
1.5. Keep the original flush-left justification.
1.6. Keep the original font colour (white).
1.7. Keep the original font body size (7 pt) and the text on one single line.
2. SLIDE NUMBER
2.1. The slide number on the banner’s lower right-hand side is automatically generated.
3. SLIDES
3.1. Duplicate the first slide as needed.
3.2. Do not change the size nor the position of the slide’s text box.
3.3. Try not to place more text on each slide than will fit in the given text box.
3.4. Replace the mock-up heading text (“Joint Research Centre (JRC)”) with your own text heading.
3.5. Set it in Eurostile Bold Extended Two or in Helvetica Rounded Bold Condensed, if you own one of these typefaces. Otherwise, keep the original typeface – Arial.
3.6. Keep the original flush-left justification.
3.7. Keep the original font colour (100c 80m 0y 0k).
3.8. Keep the original font body size (28 pt) and the heading on one single line whenever possible. Reduce the font body size if needed.
3.9. Replace the mock-up text (“The European Commission’s Research-Based Policy Support Organisation)”) with your own text.
3.10. Set it in MetaPlus Book Roman, if you own the typeface. Otherwise, keep the original typeface – Arial.
3.11. Keep the original flush-left justification.
3.12. Keep the original font colour (100c 80m 0y 0k). Use black if you need a second colour.
3.13. Keep the original font body size (22 pt) or reduce it if unavoidable.
3.14. Replace the EU-27 map mock-up illustration with your own illustration(s).
3.13. Try to keep your illustration(s) right- and top- or bottom-aligned with the main text box whenever possible.

8. Conclusions
Homogeneity of spot sampling is not the main source of variability
PBDE:
Positive results for standard analysis
Still problems for most of the labs (6// of 10) at EQS level both for extract and river sample analysis
PAH:
Acceptable results for all the samples
No systematic differences among analytical methods
AP:
Stability problems with the commercial standard
Analysis at 1/3 EQS level is still a difficult task
