Scope

Number of premature deaths due to PM 2.5 from buses in Helsinki Metropolitan Area in 2020 R↻

Definition

Data

  • mortality due to cardiopulmonary, lung cancer and other causes,
  • exposure to road traffic PM 2.5,
  • the fraction of bus exposure of total road traffic exposure

Causality

  • effect of bus type on PM 2.5 emissions and exposure,D↷
  • relationship between the exposure of PM 2.5 and mortality effects

Unit

Estimated deaths per year associated with primary PM 2.5

Formula

deltaM = Mb(eexp(bdeltaE)-1)

  • b = dose-response coefficient
  • deltaE = change in exposure
  • Mb = background mortalityR↻

Results

The mortality due to primary fine particles from buses ranged from 3 to 18 cases per year in the different bus strategies in 2020.
