Uncertainties:

  • Mortality estimate from Hoek et al. (2002)[1] 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. [2] [3]
  • No threshold was assumed in the dose-response relationship. [4] [5]

ERF for chronic PM2.5 exposure

Cause of death RR 95% Cl
All-cause 1.06 1.02-1.11
Cardiopulmonary 1.09 1.03-1.16
