Analysis method

Dep. of Chemical Engineering

School of Engineering

Aristotle Univ. of Thessaloniki

• A chamber of approximately

30 l was used

• The chamber was operating at 0.5 air changes per hour, at 23 0 C, while maintaining the relative humidity at 45%

• Air from the chambers was sampled and analysed on a

GC

E n C

Vc

A where E ( μg∙m −2 ·h −1

) is the emission rate; C

( μg∙m −3

) is the chamber concentration; A (m 2 ) is the emitting surface area; Vc (m 3 ) is the chamber volume and n (h-) is the air change rate

Conclusions

Dep. of Chemical Engineering

School of Engineering

Aristotle Univ. of Thessaloniki

• Natural materials such as marble, granite and metals do not emit at all industrial chemicals such as BTEX and carbonyls

• Significant variability among similar types of artificial materials

• Solvent-based paints are strong emitters of BTEX and carbonyls

• Wood based materials are strong emitters of acetaldehyde

• Gypsum based materials emit strongly both BTEX and carbonyls

• Formaldehyde is strongly emitted by several building materials; emissions factors are almost one magnitude of order higher compared to BTEX
