Calculating DALYs: waste
- The text on this page is taken from an equivalent page of the IEHIAS-project.
As part of the EU-funded INTARESE proejct, which contributed to the development of this Toolbox, a case study was carried out to assess the health impacts of waste management in the Lazio region of Italy.
DALYs were calculated for the three assessment scenarios. The number of attributable cases (AC) was converted to DALYs by including severity weights (S) and health state durations (D):
DALY = AC * D * S.
Severity weights were mostly adapted from the Victorian Burden of Disease Study (2005). In particular, the following severity weights/and duration of disease (D, years) were adopted.
- Mortality = 1
- Cancer = 0.44/12.6 years
- Respiratory symptoms = 0.08/1 year (prevalence)
- Low birth weight = 0.106/ 79.6 years
- Congenital anomalies = 0.17 / 79.6 years
- Severe odour annoyance = 0.03/ 1 year (prevalence)
- Occupational injuries:
- Fatality = 1
- Major injury = 0.208 / 37.3 years
- Over 3day injury = 0.10 / 3.3 years
The table and the figures below shows the Lazio study results: more information is provided in the full case study report.
