Characteristics of TVOCs Emissions in New Apartment Buildings
Abstract
Building materials are composed of very complex chemical compounds. The aims of this paper are toinvestigate the emission concentrations of indoor pollutants from new apartment house and the emissionvariation patterns during 75 days. The average value of total volatile organic compounds(TVOCs) concentrationwas 3,768 ㎍/㎥ in five new apartments. Major VOCs included toluene, ethylbenzene, m,p-xyleneand o-xylene. The average concentrations of each compound were measured as : benzene(58㎍/㎥), toluene(793㎍/㎥), ethylbenzene(438㎍/㎥), styrene(79㎍/㎥), m,p-xylene(1,210㎍/㎥), o-xylene(364㎍/㎥). The resultsindicated that the major VOCs from the new apartment were affected by building products such as onaromatic hydrocarbon compounds. TVOCs emission are characterized as high emission level at initial time(12,856㎍/㎥) and decreased through time. After a lapse of 75 days in sample house, TVOCs concentrationdecreased in about 20 times as compared with the initial concentration. The TVOCs emission profilesstrongly depended on the generation mode and the concentration of the VOCs in building material.
