Dep. of Chemical Engineering Conclusions School of Engineering Aristotle Univ. of Thessaloniki

• BTEX levels are lower than the ones measured in Greece compared to previous years – carbonyls levels are lower than the ones found in central and northern Europe

• Although wide variability among the different locations were found, concentration levels are well correlated to the emissions – Parameters that affect these correlations include:

• Air exchange rates differences among the several houses; that means that houses with similar emissions might represent different concentration levels

• the wide variability of the emission factors among similar materials, as already identified in the laboratory analysis, as well as in the review study

• the presence of building materials used such as internal and external wall ceiling finishes and thermal insulation that are not possible to be identified.

• The use of domestic cleaning products affect significantly VOC concentrations and especially BTEX levels
