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.

Abstract. Volatile organic compounds (VOCs) including terpenoids are emitted into the atmosphere from various natural sources. Damaging the plant tissue is known to strongly increase their monoterpene release. We measured the terpenoid emissions caused by timber felling, i.e. those from stumps and logging residue. The emissions from stumps were studied using enclosures and those from the whole felling area using an ecosystem-scale micrometeorological method, disjunct eddy accumulation (DEA). The compounds analyzed were isoprene, monoterpenes and sesquiterpenes. Strong emissions of monoterpenes were measured from both the stumps and from the whole felling area. The emission rate decreased rapidly within a few months after the logging. In addition to fresh logging residue, the results suggest also other strong monoterpene sources may be present in the felling area. These could include pre-existing litter, increased microbial activity and remaining undergrowth. In order to evaluate the possible importance of monoterpenes emitted annually from cut Scots pine forests in Finland, we conducted a rough upscaling calculation. The resulting monoterpene release was approximated to be on the order of 15 kilotonnes per year, which corresponds to about one tenth of the monoterpene release from intact forests in Finland.

The Association for the Control of Emissions in Products for Flooring Installation, Adhesives and Building Materials (GEV) organised a round-robin test in 2017. They wanted to establish a list of recommended testing laboratories on the basis of test results. 33 laboratories from twelve countries received three spiked test products, similar to flooring adhesives and a parquet lacquer. Less variation of results was observed compared to earlier round-robin tests, but the differences between the testing laboratories were still significant. This fact inspired a discussion regarding the analytical challenges. As an example, the parameter „sum of all volatile organic compounds (VOCs) without a target value“ includes the non-identified VOCs. This round-robin test showed a relative standard deviation of 100% and more for that parameter, which questions its reliability. The performance of 16 laboratories was rated as good by GEV. Currently, a list of recommended testing laboratories for GEV emissions testing comprises eleven laboratories from two countries. These laboratories performed well in this round-robin test and presented an appropriate accreditation according to ISO/IEC 17025.
