  2. 2. The concentration-response curves for (A) respiratory and (B) cardiac admissions Hong Kong London Source: Wong et al. Environmental Health Perspectives 2002; 110:67-76.
  3. 3. Reducing exposure and the burden of disease: Use of the concentration-response curve β is the excess risk per unit of pollutant concentration !(x 1 - x 2) is an preventable fraction of exposure and incidence of cardiorespiratory disease
  4. 4. Avoidable events caused by pollution: Doctor visits, Hospital bed-days & Deaths Pollution Air quality (microgram per cubic meter) Poor Hong Kong 6.8 million doctor visits 100 2004 64,000 hospital days 80 1,600 deaths Hong Kong $2 billion direct + $ 19 Average 60 6.8M doctor visits indirect costs billion Hong Kong 40 The preventable fraction 64000 bed-days 1600 deaths $2 Billion Objective 20 WHO Guideline 2006 0
