==Scope==

Number of premature deaths due to PM 2.5 from buses in Helsinki Metropolitan Area
{{disclink| Scope should contain temporal information}}

==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,{{disclink| Delete "Effect of bus type on PM2.5 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{{disclink|Talk:The mortality due to PM 2.5 from buses}}

==Results==

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