The mortality due to PM 2.5 from buses

Name

The mortality due to PM 2.5 from buses

Scope

Mortality effects due to PM 2.5 from buses in Helsinki Metropolitan Area

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,
• relationship between the exposure of PM 2.5 and mortality effects

Unit

Estimated deaths per year associated with primary PM 2.5

Formula

deltaM = M(eexp(bdeltaE)-1)

• b = dose-response coefficient
• deltaE = change in exposure
• M = background mortality

Results

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