Northwest women
contaminated with toxic flame retardants
Breastmilk
study confirms needs for chemical phase-out; says breastfeeding
still best for baby and mom
A new
study of 40 mothers from Oregon, Washington, British Columbia, and
Montana found PBDEs (polybrominated
diphenyl ethers) in the breastmilk of
every woman tested. PBDEs—toxic
chemicals widely used as flame retardants in furniture foams,
industrial textiles, and consumer electronics—have been shown to
have a wide range of health effects on laboratory animals. Overall,
the levels of PBDEs in the study were 20
to 40 times higher than levels found in European and Japanese women.
“The
women in the study have some of the highest PBDE levels on record,”
said Clark Williams-Derry, research director for Northwest
Environment Watch (NEW), the Seattle research and communication
center that conducted the study. “It’s more evidence that we need to
phase these chemicals out.” The study confirms other research that
PBDEs are building up rapidly in people
and the environment, with levels in many countries doubling every
two to five years.
The
report emphasized that mothers should continue breastfeeding.
Research shows that despite the presence of contaminants,
breastfeeding is the healthiest choice for infants; benefits include
reducing the risk of many illnesses in infants, as well as the
incidence of anemia and some cancers in women. Breastmilk was chosen
as a measure because it is the most convenient body fluid to obtain
and study, and because it provides a good proxy for contamination
levels experienced by the developing fetus.
Specific findings from the report include:
·
High PBDE levels:
PBDEs
were found in all 40 breastmilk samples tested, suggesting that all
northwesterners are contaminated with
PBDEs. Levels ranged from 6 to 321 parts
per billion (ppb), as measured in milk fat,
with a median level of 50 ppb (half the samples were above 50 ppb
and half below). Fifteen of the 40 women tested had at least 100 ppb
of PBDEs in their milk. These levels are
comparable to levels found in other studies in
North America, but 20 to 40 times higher than levels found in
Sweden and Japan. Median PBDE levels in North America have risen
dramatically since the late 1980s.
·
Some elevated levels of deca-PBDE:
Deca-PBDE
(PBDE-209), the most widely used form of PBDE, was detected in 24 of
the 40 samples tested; levels were as high as 4 ppb, which exceeds
the total concentration of all PBDEs
typically found in Japanese or northern European samples. Because
the bromine industry has long held that deca-PBDE
is minimally toxic, deca-PBDE has not
received the same regulatory scrutiny as other forms of
PBDEs. But new studies suggest
deca-PBDE can break down into other
forms of PBDE that are more harmful and more readily absorbed by
people.
·
Results by region:
Oregon women had the
highest median level of the four regions, with a median of 99 parts
per billion; Montana and Washington women had median levels of 55
and 53 ppb, respectively. British Columbia women generally had the
lowest levels, with a median of 32 ppb.
Further testing is
needed to clarify whether these differences are representative of
each region’s population.
·
Health effects similar to those of PCBs:
Studies on laboratory animals have shown that
PBDEs can impair memory and learning, alter behavior, delay
sexual development, and disturb thyroid hormone levels.
PBDEs are structurally similar to PCBs
(polychlorinated biphenyls),
a now-banned
class of chemicals that have been linked with a host of
developmental delays and deficits in children.
·
Exposure is unavoidable:
PBDEs
are so prevalent that all northwesterners
may be exposed to the compounds by inhaling dust, by handling
consumer products, or through food, particularly fish. Recent
studies have detected PBDEs in a wide
range of supermarket foods; as well as in orcas, other marine
mammals, osprey, and salmon. The fact that every woman tested
contained PBDEs—regardless of their
diet, age, or locale—suggests that the most effective way to reduce
contamination is to stop pollution at the source and use
alternatives.
·
Chemical phase-out needed:
The study recommends that Northwest jurisdictions ban all forms of
PBDEs from commerce, including
deca; and develop programs to monitor
chemical contaminants in people. Some states are taking action:
Washington State is including all PBDEs
in a program to phase out persistent toxic chemicals, and recently
unveiled a preliminary draft PBDE plan. An Oregon bill to be
introduced next year would phase out all PBDEs
by 2008, require the state to purchase PBDE-free products, and
enable the state health department to evaluate the safety of other
brominated flame retardants.
“It’s
time to stop using these dangerous chemicals, especially since
viable alternatives exist and are readily available," said Laura
Weiss, Oregon Environmental Council program director. "We look
forward to working with state legislators to better protect our
citizens’ health by phasing out brominated
flame retardants."
Laurie
Valeriano, policy director of Washington
Toxics Coalition, noted that the highest levels of
deca-PBDE in the study were comparable
to levels found in Swedish electronics workers who were
occupationally exposed. "It is outrageous that levels of
deca-PBDE in Northwest moms are so high.
Washington State is moving in the right direction, but
deca must be banned in electronics and
all other applications to end the contamination of our breastmilk
and bodies."
The
report also recommends requiring more rigorous scrutiny before new
chemicals are used in industry. Roughly 80,000 different synthetic
compounds have been introduced since the 1940s, yet only
a relative handful have been tested for
their potential health effects in humans.
“I’m an
average person who leads a relatively healthy lifestyle, so there’s
no reason for these chemicals to end up in my body,” said Andrea
Riseden-Perry, a Seattle-area mother who
participated in the study. “Studies on chemicals should be done up
front. And if there’s a risk the chemical shouldn’t be used.”
Sweden
was the first country to phase out some of the most toxic forms of
PBDEs in the 1990s, followed by the
European Union and the California legislature; after Sweden removed
PBDEs from the marketplace,
contamination levels in breastmilk began to decline. The report
notes that economically viable alternatives to
PBDEs do exist and companies such as Ikea and Volvo have
already eliminated PBDEs from their
products.
