1 HOW SAFE ARE SAFES? Tomasz Ł ojewski and Tomasz Sawoszczuk Faculty of Chemistry of the Jagiellonian University Kraków, Poland

2 collection of Emeryk Hutten Czapski, start of a collection late 1850’ Ermitage Catalogue de la collection de l´Ermitage monnaies et médailles polonaises 1894 Kraków, purchase of a town palace 1901 opening of the private muzeum (Elisabeth HCz) numismatic objects 1903 part of National Museum Kraków 1921 re-opened post WWII - temporary exibit. in 50’ 60’ 70’

3 Project European Centre of Polish Numismatics

4 numismatics show-room

5 F.Wertheim & C., Vien, 1896

6 analyses VOCs: historical safe modern safe indoor air air exchange rate sorbents for 3 days, VOCs plastic and paint analysis

7 air exchange rate safe filled with CO 2, 72 hours monitoring of c(CO 2 ) CO 2 sensor (Vaisalla ppm) + datalogger (Hobo) measurement and calculation by Dariusz Wilk AER = 0,34/day 1 exchange / 3 days

8 analyses sorption tubes mixed sorbent tube Carbotrap B, C and Carbosieve sIII (210/140/165 mg) (Anasorb GCB2/GCB1/CMS) SKC Part. No (EPA TO17) 1/4x3,5”, glass active sorption – 15 liter passive sorption – 10 days, room temp., 140 ml vial thermodesorber and GC/MS TD: 230CC/10 min, cold trap (-30°C), ramp to 230°C, 99°C/s GC: Rtx 5MS (Restek), 30°C/10 min, ramp to 250°C, 5°C/min MS: ionisation 70eV, m/z helium flow – 1 ml/min

9 VOCs – indoor air indoor-air: wood, BETEX, styrene TIC = 4.0

10 VOCs – old safe indoor-air: wood, BETEX, styrene TIC = 4 old safe: styrene & Co., acetic acid TIC = 57

11 VOCs – modern safe indoor-air: wood, BETEX, styrene TIC = 4 old safe: styrene & Co., acetic acid TIC = 57 modern safe: styrene, propanol, BETEX TIC = 14

12 VOCs – plastic box passive sampling for 10 days in sealed 140 ml vial indoor-air: wood, BETEX, styrene TIC = 4 old safe: styrene & Co., acetic acid TIC = 57 modern safe: styrene, propanol, BETEX TIC = 14 plastic box: styrene & Co.

13 sorbents indoor-air: wood, BETEX, styrene TIC = 4 old safe: styrene & Co., acetic acid TIC = 57 modern safe: styrene, propanol, BETEX TIC = 14 plastic box: styrene & Co. zeolites (clinoptilolite and others) bentonites (montmorillonites) actice carbon

14 sorbents indoor-air: wood, BETEX, styrene TIC = 4 old safe: styrene & Co., acetic acid TIC = 57 modern safe: styrene, propanol, BETEX TIC = 14 plastic box: styrene & Co. tested pollutant: NO 2,V NO2 = 3 ml, m (sorbent) = 0,32 g zeolites (clinoptilolite and others) bentonites (montmorillonites) actice carbon

15 VOCs – old safe with sorbents 200 g of sorbents (type 1 + type 2), 70h indoor-air: wood, BETEX, styrene TIC = 4 old safe: styrene & Co., acetic acid TIC = 57 old safe + sorbents: styrene, BETEX TIC = 27 modern safe: styrene, propanol, BETEX TIC = 14 plastic box: styrene & Co. acetic acid: with sorbent 1.1 / without 6.0 (~400 µg/m 3 )

16 VOCs – oil paint oil paint scraps, passive sampling log scale indoor-air: wood, BETEX, styrene TIC = 4 old safe: styrene & Co., acetic acid TIC = 57 old safe + sorbents: styrene, BETEX TIC = 27 modern safe: styrene, propanol, BETEX TIC = 14 plastic box: styrene & Co. oil paint: carboxylic acids, aldehydes

17 collection of Emeryk Hutten Czapski
