  2. 2. Lessons from reducing airpollution, it can be done and itworks!Prof.Pat GoodmanEurope day 13thJune
  3. 3. Talk structure Sources of air pollution Air pollution and health Examples of reducing air pollution andhealth benefits WHO work Conclusions
  4. 4. Where does air pollution comefrom? Most of the harmful pollution, the veryfine particles come from combustionprocess; Namely burning such as coal, oil wood And engine emissions, especially diesel Can also have industrial sources
  5. 5. Modern understanding of airpollutionLondon 1952
  6. 6. Dublin SMOG 1982Dublin 1982 Case Fatality RatesKelly and Clancy, Irish Medical Journal; 77:10: 322-324. 1984CFR2345678910Jan 80 Jan 81 Jan 82 Jan 83Date
  7. 7. Daytime in Dublin Jan. 1982
  8. 8. Dublin space heating 1980s The main source of particulate pollutionwas the burning of coal in open grates Space heating for homes was 100% solid fuel for social housing 80% for private housing (partially supported by Government grantsto reduce the dependence on imported oil)
  9. 9. Dublin Coal ban 30thSept 1990 Banned the marketing, sale anddistribution of smoky coal in greaterDublin

  18. 18. Harvard 6 cities study
  19. 19. Other evidence APHEA in Europe NMMAPS in the US Air pollution harmful even at low levels
  20. 20. The challenges! Cooking on open fires indoors (veryhigh exposures in developing countries) Industrial development in developingcountries Developed countries, nee dto reducefuel consumption, and thus emissions!
  21. 21. Conclusions Interventions can improve airquality Interventions can improve thehealth of the general population
