Boxes with dashed borders contain brief guidance text for completing the entries for new variables.

Scope

This includes a verbal definition of the spatial, temporal, and other limits
(system boundaries) of the variable. The scope is defined according to the use
purpose of the assessment(s) that the variable belongs to.

Exposure-response function for short-term (acute) exposure to ambient air particulate matter (PM) with an aerodynamic diameter < 2.5 µm and work loss days (WLDs).

Dimensions and boundaries relevant for the variable

  • Age of exposed population
  • Country/other geographic area

Definition

Data

Description of the data used for obtaining the value of the variable
(e.g. measurement data; mathematical method and its parameters).
Please include references (preferably using the <ref></ref> tags)
and links to original data, as appropriate.

Ostro (1987) [1]

Work loss days (WLDs):

  • 0.46% (95% Cl 0.39%, 0.53%) increase in WLDs per 1 µg/m3 PM2.5 in age group 15-64
  • change of 207 WLDs (95% Cl 176, 238) per 10 µg/m3 PM2.5per year per 1000 people ages 15-64 in general population
    • Assumes background rate of 4.5 WLDs per person aged 15-64 (general population, employement rate 63%))[2]

Causality

List of upstream variables.
The variables can be listed used descriptive (free-format) names or unambiguous identifiers
(e.g. Analytica IDs).

Unit

Unit in which the result is expressed.

Increase in no. of WLDs per 10 µg/m3 increase in exposure per 1000 people aged 15-64 (general population)

Formula

Algebra or other explicit methods if possible
(e.g. Analytica code between the ''<anacode></anacode>'' delimiters).

Result

If possible, a numerical expression or distribution.
Age group WLDs 95% Cl
15-64 207 176, 238
