Story at-a-glance -
In the mid-1970s, government entities started requiring
manufacturers to treat certain household items with
flame-retardant chemicals called organophosphates, but these
were found to be carcinogenic
Two commonly used organophosphates, TDCIPP and TPHP, have shown
up in Americans’ urine, and the former was 17 times higher in
adults in 2015 than it was in 2002
Fertility problems, hormonal changes, problems with thyroid
regulation and neurological disorders are serious problems
caused by flame-retardant exposure, and children are among
those at greatest risk

In 1973, the U.S. government passed a law requiring that all children's
sleepwear must be fire resistant. Legislators may have believed they
were preserving public health, believing such laws help keep citizens
safe. But, to borrow a phrase, the medicine is sometimes worse than the
disease.
Here's why: Fewer than five years later, scientists discovered that the
chemical used to make those flame-retardant fabrics — brominated Tris —
was responsible for rising incidences of cancer. Brominated Tris was
then banned in kids' pajamas.
By 1977, other chemicals were being used to render such articles as
baby toys, clothing,carpeting, sofas, draperies and even crib mattresses flame resistant. Growing
realization that the chemicals were causing even more health problems
led to widespread concern. Consumer Reports noted:
"In 2004, such concerns led to one of the most commonly used
flame-retardant mixtures, called pentaBDE, being voluntarily
phased out after it was linked to health problems and was
detected in alarming levels in people's bodies. Many
manufacturers began to use organophosphates in their place."
But a new, comprehensive study led by Duke University revealed that two flame-retardant chemicals in a class called are showing up in peoples' urine. Worse, the two most commonly used
organophosphates, TDCIPP and TPHP, have risen steadily in urine samples
collected between 2002 and 2015.
Experts say the reason this is an issue is because these substances
cause not just cancer, but fertility problems, hormonal changes,
thyroid regulation, neurological disorders and endocrine disruption.
Exposure to Flame-Retardant Chemicals Can Occur Several Ways
One reason organophosphates are so insidious is because they can be
breathed in, swallowed and absorbed through your skin, and accumulate in your fatty tissue, but they also
"More than 90 percent of the 857 adults and children in the
Duke-led study had two commonly used organophosphates, TDCIPP
and TPHP, in their urine. On average, the levels of one of the
chemicals, TDCIPP, were 17 times higher in adults in 2015 than
they were in 2002."
Organophosphates are used as both flame retardants and pesticides,
although different organophosphates are typically used for each
purpose. They do, however, share structural similarities. According to
National Geographic:
"Organophosphates attack the nervous system in the same way as
nerve agents like sarin … [and] are so toxic to humans that the
U.S. Environmental Protection Agency (EPA) has taken steps to
limit their availability to the public."
Why Are Toxic Flame Retardants Still Being Used?
Heather M. Stapleton, associate professor of environmental ethics and
sustainable environmental management at Duke University and one of the
study authors, noted:
"We know from animal testing that there are a variety of toxic
outcomes associated with exposure to these chemicals at high
concentrations … It's a very controversial topic.
We're using large volumes of these chemicals in furniture, yet
the data suggesting they're effective in preventing fires is
minimal to none."
Robin Dodson, an air pollution researcher at the Silent Spring
Institute in Newton, Massachusetts, said "We've known that TDCIPP is a
bad actor for a long time, yet it continues to be used."
More than a few scientists as well as consumer groups think the public
is being exposed to toxic flame-retardant chemicals unnecessarily, and
wonder if the benefits outweigh the risks, and, more specifically, if
there are any benefits at all.
Science Times notes that many are incorrectly tested for safety, and likely don't provide fire security benefits as many might expect.
Increasing numbers of state legislators are taking action against flame
retardants.
For instance, Washington state lawmakers have already prohibited the
use of certain flame-retardant chemicals (including polybrominated diphenyl ethers, or PBDEs) in children's products and furniture, but manufacturers simply replaced them with even more toxic alternatives.
How Do Organophosphate Chemicals Harm People and Animals?
Age and exposure are mitigating factors in the risks posed by
organophosphates, as younger, weaker people aren't able to eliminate
the toxins from their systems. In addition, as noted by the
Environmental Working Group (EWG):
"Flame retardants can build up more in the bodies of younger
children than in older kids or adults because they breathe in
more air and are exposed to more dust particles relative to
their body weight than adults.
The chemicals, widely used to treat upholstered furniture and
even cushioning in baby products, can escape and accumulate in
household air, and in dust on floors where toddlers and babies
play. Children's frequent hand-to-mouth activity can also
increase their exposure."
Needless to say, bioaccumulation of flame retardants can have serious
health consequences over the course of a lifetime, although health
problems may not be readily attributable to day-to-day chemical
exposure.
As mentioned, human and animal studies have linked organophosphate
flame retardants to cancer, hormonal changes and problems with
fertility.
What You Can Do
You can do everything possible to rid your home of furniture,
mattresses, clothing, food containers and other items that may contain
flame-retardant chemicals, but given their widespread use, this is
difficult and may be impractical.
Further, if you ever step out of the house, personal and environmental
hazards will likely be out there, somewhere. There are steps you can
take to limit your exposure, however:
• Get rid of the dust. Dodson and a research team
from George Washington University conducted a study on household dust and found 45 potentially harmful toxins, including flame-retardant chemicals.
Because people in the U.S. are indoors, including in schools,
offices, gyms and cars around 90 percent of the time:
"These places are usually full of dust, which is more than
just dirt. Household items like televisions, furniture,
beauty products, cleaning products, and flooring materials
shed chemicals that end up in the air and in the dust on
our floors.
These chemicals can enter our bodies from air and dust when
we breathe, touch contaminated surfaces, and accidentally
transfer them to our food or mouth with our dusty hands.
And some of these chemicals can contribute to health
problems."
Keep dust swept, dusted and vacuumed as much as possible, and maybe
even invest in a quality.
• Check the tag on new furniture. In 2015,
California instituted a law saying all new upholstered furniture
must have a label telling consumers whether it's been treated with
flame-retardant chemicals
In other states, if there's no label, ask salespersons what they
know about where upholstered pieces came from and how they were
manufactured.
If you're interested in obtaining information about upholstered
articles of furniture, you can send a sample of the polyurethane
foam to Duke University for free testing.
• Check all baby products. While some states have
precipitated the removal of certain toxic flame-retardant chemicals
in things like baby clothing, bedding, car seats and toys, many
manufactures haven't gotten the memo. EWG noted:
"In 2003, EWG analyzed breast milk samples from 20
first-time mothers to measure concentrations of brominated
flame retardants known as PBDEs. We detected these
chemicals in every study participant.
This and other studies pushed the (EPA) and manufacturers
to phase out use of PBDEs. But chemical companies
substituted Tris for PBDEs, and Americans' exposures to
these replacement chemicals has increased dramatically."

Get involved, show you're informed and support efforts to
reduce toxic chemicals
. While chemicals can do cumulative damage in your body, ridding them from your home and environment has been shown to dissipate them over time. In fact, 10 years after PBDEs were banned, research showed a nearly 40 percent decline in such chemicals in women's breast milk.
