can best be addressed through physical and laboratory examinations of the U.S. population. Currently over 100 environmental chemicals are measured in either blood or urine specimens for various subpopulations.
Recommendation 15: The National Center for Health Statistics and the National Institute for Occupational Safety and Health should collaborate in an effort to identify, using the National Health and Nutrition Examination Survey, subpopulations of older workers where chemical exposure is likely to be an important work risk factor and to develop a list of chemicals to be included in surveys of such populations in the future. Additional funds should be devoted to support this effort.
In the 1970s, the BLS carried out national Quality of Employment Surveys to describe the prevalence of and trends in job characteristics and other workplace risk factors. These nationally representative databases proved a valuable resource for assessing prevalence and trends for work risk factors. For example, the surveys were central to the development of the Job Content Questionnaire.
Recommendation 16: The National Institute for Occupational Safety and Health and the Department of Labor should collaborate and be funded to develop a survey instrument and periodically conduct surveys to describe the prevalence of and trends in job characteristics and other workplace risk factors in a manner similar to the Quality of Employment Surveys.
