| Abstract: | The effects of four substrates—an aluminium board, a plasterboard, a gypsum board and a plywood board—on volatile organic compound (VOC) emissions from an interior finishing varnish were investigated using a dynamic environmental chamber. Four major VOCs, including toluene, ethylbenzene, m,p-xylene and o-xylene, were identified in the varnish emissions. The average amount of VOCs emitted from the painted aluminium substrate was approximately 65% more than that from the painted plywood substrate during the test period. The results indicated that most VOC emissions from the painted aluminium substrate occurred in the early stage through an evaporation-like processes. However, the majority of the VOC from the plywood substrate was emitted in a later stage through a diffusion-like process. The present work confirmed that the type of substrates had a marked influence on the VOC emissions resulting from varnish. |
