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

  7. air exchange rate safe filled with CO2, 72 hours monitoring of c(CO2) CO2 sensor (Vaisalla 0-2000 ppm) + datalogger (Hobo) AER = 0,34/day 1 exchange / 3 days measurement and calculation by Dariusz Wilk

  8. analyses sorption tubes mixed sorbent tube Carbotrap B, C and Carbosieve sIII (210/140/165 mg) (Anasorb GCB2/GCB1/CMS) SKC Part. No. 226-350 (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 33-700 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 • zeolites (clinoptilolite and others) • bentonites (montmorillonites) • actice carbon 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.

  14. sorbents • zeolites (clinoptilolite and others) • bentonites (montmorillonites) • actice carbon 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: NO2 ,VNO2 = 3 ml, m(sorbent) = 0,32 g

  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/m3)

  16. VOCs – oil paint oil paint scraps, passive sampling 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 log scale
