Question

What is the the quantitative dose-response relationships between outdoor air PM2.5 concentration and mortality due to cardio-pulmonary, lung cancer, and other non-accidental causes (index Cause of death 2)?

Answer

This code gets the ovariable of this page and calculates some basic results.

Uncertainties:

• Mortality estimate from Hoek et al. (2002) 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.

• No threshold was assumed in the dose-response relationship.

ERF for chronic PM_2.5 exposure

Cause of death	RR	95% Cl
All-cause	1.06	1.02-1.11
Cardiopulmonary	1.09	1.03-1.16
Lung cancer	1.14	1.04-1.23
