Exposure: Airborne chemical exposures (ACE-JEM):

  • Vapours, gases, dusts, fumes fibres and mists (VGDFFiM)
  • Asthmagens
  • Mineral dusts
  • Biological dusts
  • Metals
  • Diesel

Coverage: Relevant job titles in within the SOC 2000

Job title and industry classification system: The UK Standard Occupational Classification System 2000 (SOC).

Calendar period: 2000-2013

Measures of exposure:  Two sub-JEMs are included based on a binary coding of the ACE-JEM exposed or non-exposed, respectively:

  • Average daily or weekly Level for exposed subjects (L-JEM) in three levels: low, medium or high
  • Proportion of subjects exposed within a given SOC code (P-JEM): 0-5%, 5-19%, 20-49%, >50%

Uncertainty in exposure measures: The JEM is based upon expert-derived ratings by occupational exposure assessors. The Jem doesn’t take accidental exposures, seasonal variation (i.e. farming) or the use of respiratory protective equipment into account. Prior jobs are not included in the JEM and could result in underestimating the exposure.

Demographic dimensions: No demographic dimensions.
