“…We have previously confirmed that the increase of emitted VOCs starts somewhere between 150 and 200°C (Dust D) (Pedersen et al., 2002). When we examined other dust sources the situation was somewhat different.…”

“…In a previous study, we found that the most prominent changes induced by heating were in the particles emitted during heating rather than the residual dust (Pedersen et al., 2001). The emission of VOCs starts in the range of 150–200°C (Pedersen et al., 2002), and the increase in the number of emitted sub‐micrometer particles occurs even at lower temperatures, 50–100°C (Pedersen et al., 2001).…”

This paper characterizes and compares emissions during heating of different dust samples relevant to the indoor environment. Characterization includes emission of volatile organic compounds when dust samples were heated to 150 and 250 degrees C (gas chromatograph-mass spectrometer), weight loss during heating to 450 degrees C (thermogravimetric analysis), and the number of particles emitted during heating towards 200 degrees C (condensation nucleus counting). Element analyses were performed for non-heated dust (inductively coupled plasma discharge instrument). Emissions of volatile organic compounds from heated dust from different sources were surprisingly similar. However, the temperature at which the emission of volatiles started varied with the dust source. For most of the samples studied, the emissions were considerable already at 150 degrees C, and increased in number of peaks and peak area at 250 degrees C. Particle emissions started around 70 degrees C regardless of the dust source. Particle emissions seemed to be affected by the content of organic material.

“…A number of other semi-volatile substances are known to be found adsorbed on particles and dust (Hyttinen et al, 2002;Pedersen et al, 2002). Several substance groups (alkylphenols, flame retardants, semi-volatile organic acids, plasticizers, and PCDD/PCDF) have been selected as examples in the following section.…”

“…It is difficult to measure SVOC emission rates from building materials or household appliances utilizing the usual test chamber methods, because the boiling points of SVOCs are higher and they are apt to adhere to the surface of the test chamber used (DIN 75201, 1992 and Ellen Katrine Pedersen et al, 2002). In Japan, the micro test chamber method -which employs a thermal desorption method in a test chamber -has been proposed as a measurement method for SVOCs emitted from building materials and household appliances (H. Katsumata et al, 2007 and K. .…”

Some types of Semi-Volatile Organic Compounds (SVOCs) that are emitted from plastics used in building materials and household appliances have associated health risks, even at low concentrations. In this study, we proposed a means of determining SVOC emissions for full-scale electrical appliances using the purging flow rate (PFR) -the relationship between the emission rate and concentration. The measurement point used to measure SVOCs was located in the downstream section of the flow. The predicted emission rates for toluene and Di-2-ethylhexyl phthalate from a liquid crystal display television (LCD TV) were 29.87 µg/m 2 ·h and 0.47 µg/m 2 ·h, which equates to the compounds measured from a piece of LCD TV using the micro test chamber method. Results demonstrate that the proposed test method is expected to have practical applications for determining SVOC emissions. However, the PFR simulated by computational fluid dynamics (CFD) analysis was substantially dependent on the CFD analysis boundary conditions in terms of the turbulence intensity or the length scale. In order to measure SVOC emission rates, it is preferable to use an experimental PFR even though CFD analysis is useful for selecting the measurement point by exampling the distribution of the PFR.
