Abstract

A woman and her son fell into sick house syndrome following the renovation of their condominium (Condo. A) by repainting of exterior walls and corridors. Since their symptoms became exacerbated in the Condo. A, they moved to the other condominium (Condo. B) where their symptoms were mitigated. We measured the concentrations of indoor air chemicals in each condominium, and compared their concentrations within and between condominiums. The order of places where their symptoms were severely exacerbated was the corridor of Condo. A > the living room of Condo. A > > the living room of Condo. B (no symptoms). Among 97 chemicals determined, concentrations of 3 chemicals,toluene, xylene and ethylbenzene, were paralleled with the order of places where their symptoms got worse. These 3 chemicals were presumably used as solvents of paint to renovate Condo. A, and supposed to trigger their symptoms. This study shows that even the renovation of exterior walls should be paid more attention to prevent sick house syndrome.
