초록
This study examined the emission characteristics and psychological effects of volatile organic compounds (VOCs) emitted from wooden boards made of Pinus densiflora and Chamaecyparis obtusa, conifer commonly found in korean forests. Boards made of those species were used to decorate interior of a test room. Different proportions of interior (20%, 40%, 60%, 80% and 100% against the entire interior of the room) were decorated. Electroencephalogram and VOCs in the test room were measured 24 hours after interior decorated. As the results, when 40% of interior of the room decorated with both species of boards, the largest amount of alpha wave was detected. For board made of P. densiflora, as the proportion of interior decorated increased both natural VOCs(NVOCs) and anthropogenic VOCs(AVOCs) were increased. on the other hand, When interior decorated with board made of C. obtusa, little differences in VOCs with different area of interior decorated was detected. Board made of P. densiflora emitted a slightly higher amount of AVOCs than boards made of C. obtusa. NVOCs emitted from board made of P. densiflora was three to fifteen times more than NVOCs emitted from board made of C. obtusa.
Abstract
This study examined the emission characteristics and psychological effects of volatile organic compounds (VOCs) emitted from wooden boards made of Pinus densiflora and Chamaecyparis obtusa, conifer commonly found in korean forests. Boards made of those species were used to decorate interior of a test room. Different proportions of interior (20%, 40%, 60%, 80% and 100% against the entire interior of the room) were decorated. Electroencephalogram and VOCs in the test room were measured 24 hours after interior decorated. As the results, when 40% of interior of the room decorated with both species of boards, the largest amount of alpha wave was detected. For board made of P. densiflora, as the proportion of interior decorated increased both natural VOCs(NVOCs) and anthropogenic VOCs(AVOCs) were increased. on the other hand, When interior decorated with board made of C. obtusa, little differences in VOCs with different area of interior decorated was detected. Board made of P. densiflora emitted a slightly higher amount of AVOCs than boards made of C. obtusa. NVOCs emitted from board made of P. densiflora was three to fifteen times more than NVOCs emitted from board made of C. obtusa.
