Abstract

Indoor chemicals are emitted not only from building materials but also from various products such as furniture and electronic appliances, which were brought by occupants. Usually these electronic appliances are made of plastics and synthetic materials. Also adhesive and sorbent were used for them. In this paper, the emission rates of aldehydes and VOCs from electronic appliances including a portable PC, a remote controller of TV, a low frequency current massager, a cellular phone, and a photo journal were measured by using a small chamber. It was found that the emission rate of formaldehyde for the portable PC during turning on was 9μg/unit h, which was 9 times higher than that of switched off. In the second experiment, a portable PC was exposed under relatively high concentration of ozone. The outlet ozone concentration from the chamber with PC was decreased as low as 50% of the blank chamber.
