Formaldehyde is one of the most extensively studied chemicals
in use today. Its health and safety properties have been researched
and characterized in depth. The evidence shows that current formaldehyde
emission standards for composite wood products are protective .
As a result, the probability of any significant adverse risk, for
the average person, is virtually non-existent.
As the leading global resins supplier to the
wood industry, Momentive is never satisfied. We continue
to develop new technology and manufacturing processes to improve
the environmental performance of our products – and yours.
committed to helping customers understand the latest scientific
research on formaldehyde and its impact on regulatory decision-making.
Formaldehyde and Indoor
“An Update on Formaldehyde,”
A federal regulatory agency primer on
formaldehyde found in indoor air, normal levels in air, major sources
in the home, symptoms of exposure and ways to reduce overall levels
“Air Quality Guidelines – Formaldehyde,”
WHO document examines how humans are exposed to formaldehyde, how
the body processes it, and potential health effects. Based on a
thorough review of existing tests and experiments, the WHO recommendeds
that indoor air levels not exceed 0.08 ppm.
Emissions from Wood and Wood Materials
“Formaldehyde Emission from Solid
Tests of five raw wood species found
all of them contain and emit formaldehyde naturally, before they
are processed or treated in any way.
“Formaldehyde Emission from Solid
A summary of investigations into formaldehyde emissions from pine
trees in New Zealand looking at differences in emissions within
and between trees on one site, different sites, and versus a range
of other species.
“Evaluating the Contribution of UF-bonded
Building Materials to Indoor Formaldehyde Levels in a Newly Constructed
Definitive EPA-led “pilot home” study
to systematically evaluate how much urea formaldehyde (UF)-bonded
building materials contribute to indoor formaldehyde concentrations
in a newly constructed home. Measured air concentrations showed
average levels decreased to less than 0.045 ppm within 30 days
and found the measured values to be 50 percent below the levels
predicted by commonly used indoor air models.
“Decay or the Decrease in Formaldehyde
Concentrations or Emissions over Time and UF-bonded Wood Panel
Studies of the decrease in formaldehyde concentrations over time
in homes finds variations but suggests a reduction of 25% to 40%
during the first four to six weeks, and reductions of 50% or more
within 18 to 24 months
“Long-term Study of Formaldehyde
Emission Decay from Particleboard,”
Long-term studies of a broad cross section of particleboard products
show formaldehyde emission levels decrease over time, with 25%
reductions in just 38 days.
Effectively Reducing Emissions from Wood Products
Barriers to Minimize VOC Emissions including Formaldehyde,”
This 2003 research evaluated ten commonly used surface finishes
for particleboard and medium density fiberboard and found that
they generally act as a very effective barrier to off-gassing,
reducing formaldehyde emissions up to 99%.
Formaldehyde Risk Assessment Findings
Protection Act, Priority Substances List, Assessment
Report – Formaldehyde”
Comprehensive regulatory risk assessment
review of formaldehyde health effects and exposure. Includes
vast amounts of data on concentrations in air (outdoor and indoor),
drinking water, food, consumer products, etc. and human exposure
assessments from inhalation and ingestion. An in-depth resource
and reference document for anyone interested in the scientific
and regulatory complexity of this subject.
“Formaldehyde: Overview of Current
Issues and Challenges for the Future,”
Excellent paper on the abundance of formaldehyde
in the world, its essential biological role, how to understand
its hazards and risks, typical exposure levels, and a review of
animal studies and the new CIIT model.
“Formaldehyde: A Case Study in Regulation,
Risk Assessment, and Industry Response,”
Based on a review of experimental studies of rodents, human statistical
studies and the regulatory history of formaldehyde, the author
finds that agency regulation has been effective, and current levels
pose little risk to humans.
