Volatile organic compounds (VOCs) from wood and their effects on artifacts are of intense interest to museum staff who must strictly manage the preservation environment. In this study, the causal substances of deterioration were inferred by comparison with laser Raman (LR) spectra of deterioration products. The artifact samples were deteriorated using VOCs from woods (WV test), and using specific substances that occur in wood VOCs (SV test). The deteriorated samples were analyzed by LR spectroscopy and the results of the WV and SV tests were compared. Hinokitiol and acetic acid were found to be two of the main causal substances of deterioration in western red cedar. Deterioration of iron and copper by spruce did not appear to be caused by acetic acid, as is generally assumed, but by some other unknown compound(s). Sensitivity to wood-based VOC components depended on the type of artifact. In western red cedar, mitsudasou (litharge) was very sensitive to acetic acid, while other artifacts were sensitive to hinokitiol. The LR method used in this study is very useful for the inference of causal substances of deterioration based on the detection of small amounts of deteriorated products such as those generated by deterioration due to wood VOCs.
