摘要：
Given the background of serious urban pollution in Hong Kong, the intake fraction (iF) of carbon monoxide due to mobile vehicles in urban area of Hong Kong is investigated and estimated to be 600 per million, much higher than those in US urban areas, Helsinki and even Beijing, indicating the high exposure level to urban pollutants in Hong Kong. The dependence of iF to the metrological factors is also discussed. Easterly and northerly winds contribute most to the total iF value. A new method of predicting ventilation rate for a city based on iF concept is proposed. City ventilation rates for different cities are calculated and compared. It is found that Hong Kong has to face the fact that it has the lowest ventilation rate and ACH.
