Titel
VOC and fine particles in a newly renovated building - a case study
Abstract
In a small case study involving an office room and a laboratory in a building equipped with a HVAC system VOC and particle samples were collected. Both rooms used for the experiments were newly renovated and low, but measurable amounts of typcal indoor VOC and SVOC were present in the air several weeks after finishing of the renovation work. The VOC concentrations decreased slowly during the test period of 3 weeks. Particulate matter in the room air was characterized regarding the size distribution by SMPS. Several samples of particles were collected on glass fibre filters to be tested for adsorbed VOC using a dynamic Headspace-GC/MS method. Since the particle concentration in the rooms was quite low, even with a sample volume of 18 m3 the total particle mass on the collected filters was below 1 mg. Only trace amounts of VOCs and SVOCs indentified in the room air could be detected on the collected particle samples after thermal desorption.
