An Exposé on ExposomesSuccess in mapping the human genome has fostered the complementary concept of mapping the "exposome." This is an interesting frontier for risk assessment, one that NIOSH will examine closely as one of our emerging issues for the 21st century. The concept of the exposome can be defined as the measure of all the exposures that an individual may experience over a lifetime in his or her environment, whether those exposures may affect the person's health, and if so, in what ways. Clearly, this is a compelling topic for those of us who are in the business of preventing illnesses that are caused or exacerbated by exposures in the workplace. Articulated in 2005 by Dr. Christopher Wild, currently the director of the International Agency for Research on Cancer, the exposome also takes into account how the impact of exposures on health are further modified by factors such as lifestyle, physical condition, and genetics. The exposome relies on the use of all exposure assessment tools. Understanding the contribution of environmental factors to disease susceptibility in terms of exposure and biological response has also been called "exposure biology" and is an integral part of exposure assessment. Exposure begins prenatally and includes insults-that is, injuries, irritations, or traumas-from environmental and occupational sources. Past occupational health studies have focused on a specific exposure or multiple exposures and the relationship to a disease. Some confounders were investigated as well. Today, many studies incorporate the interaction between genetic and environmental factors. It should be noted that the exposome also includes the study of exposures in the environment that improve or enhance health or the opportunity to attain health in greater measure. The occupational exposome is extremely important and in some cases unique from other environmental exposures. Today's occupational exposures are radically different than those of even 30 years ago. Prevention of disease should be the critical outcome from the exposome. Ironically, the measure of success will be that nothing happens-in other words, disease is prevented. Some obvious challenges may limit progress in this field of study. The exposome is highly variable and dynamic as it evolves throughout the lifetime of an individual. Ultimately, the impact of a specific environmental exposure, regardless of its origin, may be different at the individual level for different people. Past and even present exposures are difficult or impossible to quantify. Relating an occupational disease to an exposure that occurred in the past can be challenging. NIOSH has identified some specific areas that can help meet these challenges:
NIOSH's focus in the exposome lies in occupational exposures and resulting work-related diseases. I anticipate that our contributions in exposure assessment, occupational epidemiology, development of sensitive occupational methods, development and characterization of biomarkers, exposure sampling strategies, and exposure databases will advance further the field of occupational exposomics. In turn, if successful, these developments will lead to improved occupational health as occupational exposures are identified and mitigated. I invite your attention to Dr. Wild's groundbreaking thesis at http://cebp.aacrjournals.org/content/14/8/1847.full and invite you to watch for a NIOSH topic page on the exposome, which we expect to post shortly on the Web. Later this month, on February 25-26 in Washington, D.C., the National Academies will convene a national workshop to examine the exposome and the opportunities for applying the concept to improve human health. I am honored to be included as a participant in one of the panel discussions. Further information is available at http://dels.nas.edu/envirohealth/exposome.shtml. I look forward to seeing you there and to hearing your ideas on possible next steps forward for NIOSH and our partners. My thanks to Dr. Gayle DeBord, associate director for science in NIOSH's Division of Applied Research and Technology, for her assistance in preparing this month's column. |

Two New Health Hazard Evaluation Reports Now Available |
The HHE Program evaluated a possible excess in cancer incidence among current and former employees in the criminal investigation section of a police department. The investigation determined that the cancers likely were not work-related. Investigators recommended measures to address potential chemical exposures. They recommended that air filters in the local exhaust ventilation and heating, ventilation, and air conditioning systems be replaced routinely and that the amount of outdoor air supplied to occupied areas of the building be increased. Exhaust ventilation should also be added in rooms that house chemicals or emit nuisance odors. HHE Program investigators recommended that the super glue fuming chambers be replaced with units that minimize airborne ethyl cyanoacrylate exposures. Investigators also recommended that employees learn about cancer and get recommended cancer screenings.

Take Caution When Using DisinfectantsThe use of disinfectants has increased because of the concern about exposure to infectious agents, such as the 2009 H1N1 influenza virus. A patient seen recently at the Michigan State University Clinic, one of the clinics in the Association of Occupational and Environmental Clinics, complained of respiratory symptoms that had developed at work after exposure to a spray disinfectant. Aerosol cans of disinfectant had been distributed by supervisors and, when people coughed at work, disinfectant was inappropriately sprayed in the air instead of surfaces, according to the clinic. A summary of the allergenic/irritant effects of disinfectants can be found at www.oem.msu.edu/userfiles/file/News/v20n2.pdf. |
American Society of Safety Engineers, Technical ReportThe American Society of Safety Engineers has developed a technical report, Guidelines for Addressing Occupational Risks in Design and Redesign Processes (https://www.asse.org/shoponline/products/trz790-001-2009.php).

Major NIOSH Finding Featured in Emerging Infectious Diseases JournalNIOSH scientists published a major finding in the U.S. Centers for Disease Control and Prevention's (CDC) journal Emerging Infectious Diseases on the relationship between silicosis and pulmonary mycosis. Silicosis is a work-related disease caused by exposure to respirable silica dust. Pulmonary mycosis is a serious, irreversible but preventable disease caused by fungal infection. Scientists linked the two and found that some workers may be at risk for job-related co-exposure to silica dust and fungi. http://www.cdc.gov/eid/content/16/2/318.htm Workplace Safety and Health Training Positively Impacts WorkersOccupational health and safety (OHS) training is an important part of managing workplace hazards and risks. A Systematic Review of the Effectiveness of Training & Education for the Protection of Workers reports on a study conducted by the Institute for Work and Health and NIOSH to determine whether OHS training and education programs have a beneficial effect on workers and firms.

The Health Hazard Evaluation (HHE) Program evaluated exposures to hazardous metals, including lead and cadmium, during electronics recycling efforts at four prisons. Investigators recommended that these facilities be in full compliance with Occupational Safety and Health Administration standards, including record keeping requirements, communication requirements, compliance plans, and medical surveillance. HHE Program investigators also recommended that preplacement examinations for cadmium exposure be identical to periodic examinations so that baseline health status can be obtained prior to exposure. Investigators additionally recommended that a detailed job hazard analysis be conducted prior to beginning any new operation or before making changes to existing operations.
