Emission rates

Exposures to airborne fine particulate matter with a diameter of <2.5μm (PM2.5) are linked to multiple negative health effects, including cardiovascular and respiratory disease. Existing investigations of PM2.5 primarily focus on external sources and exposures, because outdoor air is easier to observe, and therefore, more widely monitored. However, as people spend up to 70% of their time in their own homes, exposures to indoor pollutants could have a greater impact on health. One method of investigating indoor exposures in a stock of houses is by modelling them.

Home electrical appliances release hazardous chemical substances produced by the effects of heatingduring their operation. The present study investigated the emission rates of chemical substances onhome electrical appliances such as microwave ovens, vacuum cleaners, electric heaters, electricblankets, multimedia players, electronic dictionaries, MD players and notebook PCs.The VOCs emission rates of comparatively small products were measured using a small-scaleenvironmental chamber with a volume of 0.065 [m3].

In approach to alleviating the problems causing ‘sick building syndrome’, many types of indoor air pollution removal products have been developed. In the various performance evaluation methods for these removal products, the pollutant constant-emission te
