TheTVOC value can be obtain on the gas chromatographand it is defined as the sum of all peak areasof all VOCs which are emitted between hexane andhexadecane. The sum of areas is then calibrated tothe value which is equivalent to toluene.This paper concentrates on VOC emissions sourcesin a newly built and equipped room. Materialused for building was gypsum board. The PVC materialused for floor covering was glued by the rubbersolvent glue. Furniture in the room was madefrom laminated particleboard.Goal of the ResearchThe main goal of the research was to find dependencyof qualitative and quantitative contributionof VOCs emissions on time. We tried to determinethe impact of all interior components (usedbuilding material, PVC flooring and glue used forflooring gluing, furniture) on indoor air pollutionand its changes in time.MATERIALS, EQUIPMENTAND METHODSMeasured space – newly built room with PVCflooring glued by the rubber solvent glue.− dimensions of the room 4880 mm x 3170 mm xx 3770 mm; two windows and one door whichwere closed during the testing− dimensions of flooring: 3170 mm x 4880 mm;with ratio 1 m 2 to 3.77 m 3 of the room spaceTab. 2: Requirements determinate for the amount of TVOC in indoor air of residence rooms (Jokl, 2002 – standardMZ ČR č.6/2003)Toxic VOCNPK average[μg.m –3 ]NPK optimal[μg.m –3 ]short-term long-term short-term long-termFormaldehyde 120 60 60 60TVOC 600 300 300 300AnnotationConstituent VOC couldnot exceed the limitmandated in the standardMZČR 6/2003
