Presentation topics

What has been achieved?

1. Analysis of VOCsInterpret results of various methods

2. Concentation – damageCompilation of data

3. Critical concentration levels - guidelinesLOAED values to contest

4. Mitigation methodsTechnology available

5. Forming working groupHere we are!

Inventory

1. How many of you are actively involved in research on:a. Sampling IAPs or PM?b. VOC emission and material testing?c. Susceptibility of materials to IAPs or PM?d. Mitigation strategies for IAPs or PM?

2. How many of you look at IAPs in relation to other risks?

3. How many of you are here to collect information?4. Is the information you got applicable in your:

a. Research?b. Museum practice or advice?

5. How many of you work with guidelines for IAPs and PM?

Discussion of results

• Dyes highly susceptible to photo-oxidation undergo no synergistic or additional effect in an acidic environment – or too small to notice

• Newspaper behaves highly susceptible to photo-oxidation

• Copy paper moderately susceptible to photo-oxidation undergoes synergistic degradation in an acidic environment

• High LUV sensitive: IAP comparatively small• Medium/low LUV sensitive: same order

From IAP to IAQ – where next?

Questionaire

1. Which information do you still need to deal with IAQ in a museum context?

2. What should have priority in IAQ work from a:a. museum application perspective?

b. research and development perspective?

3. What kind of forum do you need:a. exchange of r&d in progress in specialised topics

b. discussions on mixed but separate topics

c. general overview of various topics with focus on interactions

d. mega conference overwhelmed by presentations

Conclusions

• IAP has developed into IAQ• IAQ = exchange forum, presentation platform,

information source• IAQ is only a step away from PC• Need for a PC conference with focus on

interactions, on special topic discussions• Who? Where? When?

Risk of low RH?IAP

Thank you all!

Thank you Padova!!!!
