Occupational epidemiology and exposure assessment
- 1. Occupational Epidemiology and Exposure Estimation John Cherrie www.OH-world.org
- 5. Asbestos lung cancer epidemiology…
- 9. Changes…
- 14. From source to dose ambient concentration exposure internal exposure source dose disease
- 25. Structured subjective assessment Where... i = intrinsic emission h = handling lv = local controls etc.
- 26. Exposure estimation... Change in technology Ventilation introduced
- 27. Validity... 10 1 0.1 0.01 0.001 0.001 0.01 0.1 1 10
- 31. A serious public health risk...
- 33. Mesothelioma risk for a child... Age 10, exposed to 1fibre/ml for one day
- 34. So what should we do?
- 36. What are your conclusions?
