Beskrivelse af JEM

Name: WOOD JEM

Exposure: Airborne inhalable wood dust exposure.

Coverage of occupations: All ISCO-88 codes (International Classification of Occupations) – 18 with exposures different from 0, these are:

 

 Job title and industry classification system: The JEM uses the ISCO88, which is almost equal to the Danish DISCO-88.

Calendar period: The JEM covers years 1978-2007.

Measures of exposure: Unit of measurement is geometric mean level of wood dust in mg/m3. There is an annual trend of -7.8% for wood dust exposure after 1997 significant at a <0.05 level. This can be used to assign exposure for the period covered by the database 1978-2007. For years prior to 1978 and after 2007, where no measurements are available, it could be resonable to assume there are no immediated trends – and there for a broken stick model could be applied, see figure below. Alternatively the estiamted trend could also be assumed to continue.

Uncertainty in exposure measures: Standard error of predictions are available.

Demographic dimensions: The JEM contains  non-country specific exposure estimates as well as country specific estimates. This are available for Denmark, Norway, the Netherlands, Finland, the UK and France. The JEM has no geographical dimensions within Denmark.

Access: To obtain access to data follow the application procedure on this site. You will find an overview of the access posibilies to the JEM  here  Hent dokument.

A report is available describing 12,653 dust measurements from wood related industries from Denmark, Finland, UK, France, Norway, Netherlands. Methodology similar to the paper on modelling of occupational respirable crystalline silica exposure for community-based studies (Peters S, et al. Modelling of occupational respirable crystalline silica exposure for quantitative exposure assessment in community-based case-control studies. J Environ Monit. 2011 Nov;13(11):3262-8).

Forskningsprojekter om eksponering for træstøv i DOC*X

Der forskes i forskellige sammenhængen mellem træstøv og sundhed inden for DOC*X, hvor jobeksponeringsmatricen WOOD JEM benyttes som eksponering.

Der forskes blandt andet i sammenhængen mellem iskæmisk hjertesygdom og partikeleksponering såsom træstøv. Risikoen for akut myokardieinfarkt undersøges ved henholdsvis kort- og langtidsudsættelse for bestemte hovedgrupper af partikeleksponering, nemlig kvartsholdigt respirabelt støv, organisk støv (endotoxin og træstøv), udstødningen fra forbrændingsmotorer samt metalholdigt støv.
