- The German Exposure Factors Database RefXP: the German Federal Environment Agency provides extensive current data facilitating population-based exposure modeling and assessment. These reference data describe inter alia food and drinking water consumption, time-location and activity patterns, soil and dust ingestion, residential characteristics and anthropometrics of the general German population typically stratified by gender and age.
- U.S. EPA Exposure Factors Handbook 2011 Edition: this handbook was first published in 1989 and later updated in 1997 to provide statistical data on the various human factors used in assessing exposure. This revised edition of the handbook provides the most up-to-date data on these exposure factors. The recommended values are based solely on our interpretations of the available data. In many situations different values may be appropriate to use in consideration of policy, precedent or other factors.
- U.S. EPA Child-Specific Exposure Factors Handbook (Final Report) 2008: this handbook to provide information on various physiological and behavioral factors commonly used in assessing children’s exposure to environmental chemicals. Children have different exposure circumstances than do adults.
- 2013 Canadian Exposure Factors Handbook (pdf version, 4.8Mb): to better reflect current Canadian population characteristics, behaviours, and activities the 1997 Compendium of Canadian Human Exposure Factors for Risk Assessment was replaced in 2013 by the Canadian Exposure Factors Handbook (Richardson GM and Stantec Consulting Ltd. (2013)).
- Australian Exposure Factor Guide (2012): The Australian exposure factor guide was prepared as a companion to the 2012 update of the enHealth guidance document ‘Environmental Health Risk Assessment: Guidelines for assessing human health risks from environmental hazards'. This latter document provides a national approach to environmental health risk assessment as well as a general environmental health risk assessment methodology, applicable to the range of environmental health hazards (i.e. chemical, physical, biological).
- Japanese Exposure Factors Handbook (summary page in English): The Japanese Exposure Factors Handbook was developed in 2005-2006 by the National Institute of Advanced Industrial Science and Technology (AIST) (Gamo M. and Futatsumata M., 2006). Previously conservative default factors, arbitrary factors set by assessors, or factors cited from handbooks developed in other countries were often used in exposure/risk assessments per-formed in Japan. For that reason an exposure factors handbook compiling Japanese data have been required for conducting realistic exposure assessment in Japan.
