Revision as of 12:03, 21 February 2008

Scope

Concentration-response to PM2.5 describes the quantitative dose-response relationships between outdoor air PM2.5 concentration and mortality due to cardio-pulmonary, lung cancer and other non-accidental causes.

Definition

Causality

List of parents:

  • None

Data

List of data files or sources:

  • Dockery et al. 1993[1]
  • Pope et al. 2002[2]

Formula

The model randomly samples between the effect estimates provided by the two studies. See the model for more detailed description.

Unit

m3/μg D↷

Result

These coefficients are defined as distributions around estimates of central tendency for each cause of death.

Relative increase of mortality per 1 μgm-3 increase of outdoor PM2.5 concentration. Values were drawn with equal probability from the two distributions reported in [3], [4]

Distribution of dose response coefficient for

  • cardiopulmonary mortality 1.014 (0.0053-0.0254)
  • lung cancer mortality 1.016 (-0.0009-0.0364)
  • all other mortality 1.002 (-0.0073-0.0102)

Uncertainties:

  • Mortality estimate from Hoek et al. (2002)[5] was not included due to many confounding factors related to mortality, e.g. road noise.
  • Probability for PM2.5 assumed to be the true cause of the effects in 70 %, 90 %, and 10 % for cardiopulmonary, lung cancer and all other mortality, respectively (author judgement).
  • Toxicity differences between ambient air particles and the particles generated by different bus types were not taken into account due to lack of comprehensive data. [6] [7]
  • No threshold was assumed in the dose-response relationship. [8] [9]
