Based on the review of the international research studies on air pollution (European Commission, 2005; USEPA 2006; WHO, 2006; DEFRA, 2007), the potential health effects can be subdivided into short-term acute and long-term chronic impacts. Short-term effect usually refers to a dose of exposure within 1 hour to 1 day. Chronic effect generally refers to continuous exposure in a 70-year life-time period. Based on the study findings, Table F1.1 summarises the health effects of different major air pollutants.
