Multiple chemical sensitivity (MCS) patients have an acute hypersensitivity to specific chemicals even at very low concentrations. Therefore, it is difficult to clarify the chemicals relating to MCS symptoms. In order to find out the chemical(s) that induce the symptoms of a woman patient living in Sapporo City, we compared the concentrations of chemicals in indoor air of house A where her symptoms had appeared, to those in house B where her symptoms had been improved. Of the 75 chemicals surveyed, the 7 compounds (α-pinene, β-pinene, 2-ethyl-1-hexanol, 2-(2-butoxyethoxy)ethanol, texanol (2,2,4-trimethyl-1,3-pentanediol 1-monoisobutylate), diethylhexyl phthalate, and bornyl acetate) were detected in the house A over two-fold higher concentrations than in the house B. This result suggests that, these 7 chemicals may relate to the cause(s) of MCS symptoms of this patient. Thus, it is important to survey extensively the chemicals possibly responsible for the hypersensitive reactions of each MCS patient, although the mechanism inducing MCS symptoms is still obscure.
