Job-Exposure MatrixA job-exposure matrix may be defined as a cross-classification between a list of job titles and a list of agents to which persons carrying out the jobs may be exposed.
Hazardous AgentsAgents
• P : the prevalence of exposure(%)• L : the average level of exposure among
the exposed(in concentration units)
Periods
J b Job (Occupation / Industry / Task)
Types of JEM
• Industry-specific JEM (ISJEM) : cross-classifies
exposures only for a limited group of occupations
and tasks within one certain industry, and oftenand tasks within one certain industry, and often
includes more-detailed definitions on the exposure
axis.
• General population JEM (GPJEM) : all possible
occupations that can occur in a population areoccupat o s t at ca occu a popu at o a e
represented and standard or national classifications
are often adopted.

Approach for the Construction of JEM
1. Case-based JEM : Analysis of data which are
collected from death certificate, compensation of
occupational diseases the cases reported fromoccupational diseases, the cases reported from
surveillance system and so on.
2 Exposure-based JEM : Analysis of exposure2. Exposure-based JEM : Analysis of exposure
assessment data which are collected from literature,
epidemiological survey, national exposure database
and so onand so on.

CAREX(Carcinogen Exposure)
• CAREX database was constructed with support from the Europe Against Cancer program of the European Union (EU), and is well known for the i t ti l i f ti t ti l t iinternational information system on occupational exposure to carcinogens.
• This database provides selected exposure data and documented estimates of the number of exposed workers by country, carcinogen, and industry.

Conclusion
• Occupations can be regarded as a proxy for exposurebto asbestos.
GP JEM id d l• GP-JEM may provide an easy and low-cost way toassess exposure based on occupation and industry titlelalone.
I d i i d GP JEM ll ki d f• In order to construct optimized GP-JEM, all kinds ofavailable data should be compiled at the national level
d ld l b li k d h h SOC ( d dand could also be linked through SOC (standardoccupation code).
