Semi-volatile organic compounds from artificial products can persist for long periods in indoor environments, and several semi-volatile organic compounds can lead to human diseases via inhalation, ingestion and dermal pathways. Mass-transfer models are an excellent alternative to experimental testing for predicting the transportation of semi-volatile organic compounds in indoor environments. This report presents a comprehensive review of mass-transfer models for semi-volatile organic compound transportation in indoor environments, assuming that semi-volatile organic compounds are well mixed and exhibit uniform properties in the indoor space. The mass-transfer models, including emission and surface/particle sorption models, and methods for determining material emission and mass flux on sorptive and airborne surfaces are discussed. Factors affecting the emission rate and gaseous concentration are analysed, including the airflow rate, surface sorption, particles, temperature and humidity. Finally, a few research needs are highlighted in this review.

The major volatile components in two solvent-based paints, two thinners, and four adhesives have been identified by a method involving pre-treatment by solvent dilution, filtration, and gas chromatography-mass spectrometry. The non-volatile components in these wet building materials have been determined by infrared spectroscopy. The results have shown the major volatile organic compounds in one-component polyurethane varnish and alkyd paint thinner to be nonane, decane, undecane, xylene, ethylbenzene and ethyltoluene. The main film-forming matter in cement floor paint has been identified as styrenated acrylic emulsion, with the volatile components being mainly butyl acetate, decane and benzene series. The basic substances in these adhesives were polychloroprene, styrene butadiene carboxylated latex, or polyvinyl acetate emulsion. The primary volatile compounds in two adhesives were methyl acetate, and many branched-chain and normal alkanes, while those in the other two adhesives were toluene and benzene.

Headspace technique and gas chromatography method with mas detector has been used for the determination of volatile organic compounds (VOC) emitted from various building and finishing materials, such as sealing foams, mounting strips, paints, varnishes, floor coverings. The tests were carried out for different temperatures (in the temperature range of 60 to 180 °C) and the time of heated vials with tested materials inside. These tests were conducted to verify the possibility of use this method of determination the VOC emission. Interpretation of chromatograms and mass spectra allowed to identify the type of compounds emitted from the tested materials and the optimum time and temperature for each type of material was determined. The increase in heating temperature of the samples resulted in increase the type and number of identified compounds: for four materials the increase was in the whole temperature range, for others it was from 90 °C. On the other hand, emission from mineral wool was low in whole temperature range. 30-minutes heating of the samples was sufficient to identify emitted compounds for most of tested materials. Applying a longer time, i.e. 24 hours, significantly increased the sensitivity of the method.
