For Immediate Release: April 13, 2011
Brookfield, Wis. – Last week, the National Academy of Sciences (NAS) concluded that the U.S. Environmental Protection Agency's (EPA) draft health assessment of formaldehyde required "substantial revision." The NAS disagreed with a number of the EPA's key findings, including that formaldehyde causes leukemia, specific cancers of the respiratory tract and other noncancerous health effects, such as asthma. The report also provided recommendations for the EPA to revise its draft, including a "road map" for generally improving the agency's risk assessment process. It is now up to EPA officials to decide how to address the NAS recommendations.
NFDA closely monitors domestic and international formaldehyde studies since the chemical is widely used in embalming products. Last year, after more than a decade of study, the EPA issued a draft risk assessment of formaldehyde, which was intended to update its Integrated Risk Information System (IRIS) with recent studies that assessed the health hazards posed by inhaling formaldehyde. Many of these studies have classified formaldehyde as a carcinogen; however, because of intense debate over whether inhaled formaldehyde poses a risk of nasopharyngeal cancer (back of the throat), leukemia or asthma, the EPA asked NAS to evaluate its draft IRIS assessment.
Key findings of the NAS report:

Recent Research and NFDA Education Efforts
In 2004, the International Agency for Research on Cancer (IARC), the leading international cancer agency, reclassified formaldehyde as a Group I carcinogen after finding a link between formaldehyde and nasal cancer. In 2009, IARC found sufficient evidence to conclude that formaldehyde exposure may cause leukemia, a disease of the blood and bone marrow.
Following a 20-year study of embalmers, the National Cancer Institute published a report in 2009 that found a link between embalming and death from myeloid leukemia, with the greatest risk found among those who practiced embalming for more than 20 years and who experienced great formaldehyde exposure in the preparation room. This study was not mentioned in the NAS report.
In 2010, an expert panel of the National Toxicology Program (NTP) concluded that formaldehyde should be listed as a known human carcinogen in its "12th Report on Carcinogens." The NAS report noted, however, that some scientists disagree with the IARC and NTP conclusions and have published studies that raise questions about those findings. The NTP's determination for formaldehyde has not yet been finalized.
In spite of a lack of conclusive evidence showing a definitive link between various forms of cancer and formaldehyde, NFDA has used these appraisals of the health hazards associated with formaldehyde to educate funeral professionals and provide guidance on reducing exposure to the chemical in the preparation room.
In 2009, NFDA issued its "Formaldehyde Best Management Practices," which offer guidance on risk-reduction practices that funeral directors should adopt to lessen their exposure to formaldehyde and thus minimize associated health risks. The "Formaldehyde Best Management Practices" can be found on the NFDA website, www.nfda.org/additional-tools-embalming.
Last year, NFDA issued its groundbreaking ventilation study, which identified the features of a ventilation system that will effectively remove formaldehyde from the embalmer's breathing zone and reduce risk of formaldehyde inhalation. Ventilation has been found to be the single most effective way to reduce formaldehyde vapor levels and thus control associated health risks. NFDA undertook this study because there were no consensus formaldehyde ventilation standards applicable to funeral homes. Information about the ventilation study can be found on the NFDA website, www.nfda.org/ventilation.
Funeral homes that carefully follow NFDA's "Formaldehyde Best Management Practices" and the recommendations of the ventilation study can reduce formaldehyde exposure in the preparation room. Careful control of formaldehyde exposure in the preparation room continues to be the strong recommendation of NFDA for protecting the health and safety of embalmers.
NFDA will soon begin a comparison study of formaldehyde-free embalming products.
NFDA is the world's leading funeral service association, serving 18,500 individual members who represent more than 9,900 funeral homes in the United States and 43 countries around the world. From its headquarters in Brookfield, Wis., and its Advocacy Division office in Washington, D.C., NFDA is the worldwide source of expertise and professional resources for all facets of funeral service. Through education, information and advocacy, NFDA is dedicated to supporting members in their mission to provide families with meaningful end-of-life services at the highest levels of excellence and integrity.
