The purpose of this study was to measure the concentration of cooking-generated particles and to assess the health risk of the occupants. Numerous particulates are released from the kitchen when people are cooking, and diffused to other spaces in house, which would adverse the health of occupants. Sufficient ventilation is needed to decrease the PM2.5 concentration. To analyze the PM2.5 concentration, field measurements were performed on a cooking condition. A case study was performed based on the ventilation type including natural and mechanical ventilation. Three cases were designed: single-sided natural ventilation, cross-ventilation, and mechanical ventilation. The PM2.5 concentration was measured for 30 min, with a cooking time of 16 min. According to the analysis, the PM2.5 concentration increased 3.8 times more than the 24 h standard (50 mu g/m(3)). The PM2.5 concentration in the living room was slightly greater than that in the kitchen. The particulate matter also rapidly diffused to other spaces. Moreover, the health risk increased by up to 30.8% more than in the base scenario. Therefore, additional ventilation strategies are needed to alleviate the diffusion of cooking particles.
