Name: Endotoxin JEM, an Insustry Exposure Matrixsurem.

Short describtion: 3,200 endotoxin measurements and 3540 organic dust measurements from Denmark, Switzerland, Spain, Germany, Netherlands, Canada, and Norway. 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. Though it is important to know that no prior is included in the analyses

Reference: A short description is available and included in the spread sheet with the two Industry Exposure Matrices (IOMs). Basinas I, Wouters IM, Sigsgaard T, et al. Development of a quantitative job exposure matrix for endotoxin exposure in agriculture. Occup Environ Med 2016; 73.

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.

Exposure: Airborne endotoxin exposure in the work environment.

Coverage: Please see below. You can chose to assume that other industries are not exposed to endotoxin  –  the most important industries are included – but some industries are not covered. Only industries where we managed to find measurements are included in this IOMs.

Industries: Growing of cereals (except rice), leguminous crops and oil seeds;Growing of vegetables and melons, roots and tubers;Growing of other non-perennial crops;Raising of dairy cattle;Raising of sheep and goats;Raising of piglets;Production of pigs (piglets and finishers);Production of pigs for slaughtering;Raising of poultry;Raising of fur animals, etc.;Mixed farming;Industrial and post production processing;Post-harvest crop activities;Seed processing for propagation;Production of pork;Production of other meat;Processing and preserving of poultry meat;Production of meat and poultry meat products;Other processing and preserving of fruit and vegetables;Manufacture of grain mill products;Manufacture of bread, fresh pastry goods and/or bakery products;Manufacture of bread; manufacture of fresh pastry goods and cakes;Manufacture of fresh bakery products;Manufacture of sugar;Processing of tea and coffee;Manufacture of prepared feeds for farm animals;Manufacture of malt;Sewerage;Treatment and disposal of non-hazardous waste;Disposal of waste with energy production;Wholesale of flowers and plants;Wholesale of fruit and vegetables;Warehousing and storage;Landscape service activities

Job title and industry classification system: The JEM uses the DB-07 classification and DISCO-88.

Calendar period: Years covered are 1990 – 2009. Recommendations outside the period not fixed. Not indications of any strong trends.

Measures of exposure:  Geometric mean in EU/m3. Within the dataset, the presented endotoxin value corresponds to the year 2002, and the gradient required to extrapolate values for subsequent years is as follows:

  • For the period 1990-2002: An annual positive gradient of 2.9% is to be applied from 2002 backwards.
  • For the period 2002-2009: An annual negative gradient of 2.9% is to be applied from 2002 onwards.
  • For years prior to 1990: The value obtained in 1990 remains applicable.
  • For years from 2009 onwards: The value obtained in 2009 remains applicable.

Uncertainty in exposure measures: Standard error of predictions.

Demographic dimensions: There are no geographical dimensions within Denmark. Country specific estimates are not available.
