Domestic sampling: exposure assessment to moth repellent products using ultrasonic extraction and capillary GC-MS.
Moth repellent agents are considered major contributors to indoor air pollution. In this study, the chemical contamination of clothes due to their direct or indirect exposure to moth repellent agents such as p-dichlorobenzene, naphthalene and camphor were investigated. Cotton cloths were used as clothing simulant. They were analyzed using ultrasonic extraction followed by GC-MS analysis. Extrapolated results indicate that a regular cotton shirt indirectly exposed to these chemicals in a storage cabinet can contain up to 7, 3 and 7.5mg of p-dichlorobenzene, naphthalene and camphor, respectively, even after one-hour of airing. Passive sorptive sampling using polydimethylsiloxane-coated stir-bars and ultrasonic extraction followed by GC-MS analysis was used to monitor the concentration distribution in a wardrobe.
