Exposure: Diesel exhaust

Job title and industry classification system: The occupations in the matrix were recoded to SSYK96 (a Swedish adaption of ISCO88). Due to the lower precision in the occupational codes in ISCO 88 than in NYK-83, the matrix was extended with assessments of the proportion of exposed persons within each occupation. The occupational codes were translated to the European version of ISOC88.

Calendar period: The matrix was extended to include the calendar period up to 2020.

Measures of exposure: Elemental carbon (EC) was used as an indicator for exposure to diesel exhaust (µg EC/m3). The point estimate for a randomly drawn individual in an occupation is obtained by multiplying the proportion exposed with the exposure intensity the specific year.
