28/06/20152 © 2010, VITO NV Introduction Integrated science assessment for paticulate matter (US EPA 2009) “a causal relationship exists between long-term exposures to PM2.5 and cardiovascular effects” “a causal relationship exists between long-term exposures to PM2.5 and mortality” Ozone and your health (US EPA 2009) “Ozone can irritate your respiratory system, reduce lung function, aggravate asthma, etc.”

28/06/20154 © 2010, VITO NV » DALYs » Combine information on the ‘quality’ and ‘quantity’ of life » Give an indication of the potential number of ‘healthy’ life years lost due to premature mortality or morbidity » DALY calculation = N x S x D » Number of people with environment-related morbidity or mortality » Severity factor (0=healthy; 1=death) » Duration of disease Disability Adjusted Life Years (DALYs)

28/06/ © 2010, VITO NV Uncertainties » Framework of Knol Anne (2010) » Context uncertainty e.g. selected stressor, endpoint » Model structure uncertainty e.g. causal relationship » Parameter & input data uncertainty e.g. health statistics Knol, A., Health and the Environment: assessing the impacts, addressing the uncertainties, Thesis Utrecht University, the Netherlands.

28/06/ © 2010, VITO NV DALYs in general » DALYs give an indication of the potential, relative order of magnitude of different (environmental) health problems, and can not be presented as absolute or completely representative numbers. » Smoking, genetic ability, food consumption etc. » Competing risks
