テフロン 「有害物質使用」で対立 デュポン、米環境保護局と
米化学大手デュポンがテフロン製造に用いる化学物質の人体への有害性を巡り、米環境保護局(EPA)と対立している。EPAはデュポンが20年にわたって有害物質の使用を公開しなかったとして最高2億ドル(約220億円)の罰金を科すと発表。デュポン側は「無害」を主張し正式に異議を唱える予定だ。
問題の物質は「プルフ一ルオロオクタン酸」(PFOA)で、フッ化ポリマー製造過程で用いる。フッ素加工のフライパンや衣類の保護仕上げなどに幅広く使われている。肝臓障害などを起こす可能性があるとして、規定値を超えて使った企業には報告義務がある。
EPAによると、デュポンの米ウエストバージニア工場近くの水源で規定値を超えるPFOAが見つかり、工場に勤務していた妊婦からもPFOAが検出されたにもかかわらず、同社はEPAへの報告を怠った。

Press Advisory: EPA Takes Enforcement Action Against DuPont For
Toxic Substances Reporting Violations
http://yosemite.epa.gov/opa/admpress.nsf/b1ab9f485b098972852562e7004dc686/afdc5785fd9ee05585256ecb00522cee?OpenDocument
EPA’s Office of Enforcement and Compliance
Assurance (OECA) is taking an administrative action against E. I.
DuPont de Nemours and Company (DuPont) for two violations of the
Toxic Substances Control Act (TSCA) and one violation of the
Resource Conservation and Recovery Act (RCRA). These violations
consist of multiple failures to report information to
EPA about substantial risk of injury to human health
or the environment from a chemical during a period
beginning in June of 1981 through March of 2001. Companies are
required by TSCA to report such information immediately. EPA has
the authority to seek a penalty of $25,000 per day for violations
occurring before January 30, 1997, and up to $27,500 per day for
violations occurring thereafter, for each day that DuPont failed
to report the information. EPA alleges that DuPont did not submit
to the Agency information the company had obtained regarding the
synthetic chemical Perfluorooctanoic Acid (PFOA). PFOA is used in
the manufacturing process for fluoropolymers, including some
TeflonR products, at DuPont’s Washington
Works facility in Washington, West Virginia.
In 1981, the company observed PFOA in blood samples taken from
pregnant workers at the Washington Works facility and at least
one woman had transferred the chemical to her fetus. DuPont detected
the chemical in public water supplies as early as the mid-1980s
in West Virginia and Ohio communities in the vicinity of the
Washington Works facility. By 1991 DuPont had information that
the chemical was in water supplies at a greater level than the
company’s exposure
guidlelines indicated would be without any effect to members of
the community. In 1997, DuPont failed to provide EPA with all
toxicological information the company had regarding PFOA, despite an EPA
request for such information under the terms of an EPA-issued
RCRA permit. An attorney working on a class action suit on behalf
of citizens in Ohio and West Virginia brought this information to
the EPA in 2001.
The information that DuPont had obtained about PFOA was, and
continues to be, pertinent to the Agency's ongoing work to better
understand PFOA. Since April 2003, EPA has been working
cooperatively with DuPont, 3M, other companies, and interested
parties to develop the information necessary to better understand
the sources and exposure pathways of PFOA. This public effort
will lead to the development of information that will assist the
Agency in determining what voluntary or regulatory actions, if
any, would be appropriate to protect human health and
environment. This rigorous scientific review will ensure that any
future regulatory action on PFOA is protective of public health
and supported by the best scientific information. EPA is working
to complete a revised risk assessment, which will be released in
Fall 2004 for public peer review by the Agency’s Science Advisory Board. To learn more

Upcoming PFOA ECA Meetings
http://www.epa.gov/opptintr/pfoa/
On April 14, 2003, Stephen L. Johnson, Assistant Administrator for Prevention, Pesticides, and Toxic Substances, signed a Notice for publication in the Federal Register on perfluorooctanoic acid (PFOA) and fluorinated telomers. With this Notice, EPA is releasing a preliminary risk assessment on PFOA, and is starting a public process to identify and generate additional information to strengthen the risk assessment. EPA is also inviting interested parties to monitor or participate in negotiations on one or more enforceable consent agreements (ECAs) to obtain additional data concerning PFOA and fluorinated telomers which may metabolize or degrade to PFOA. Comments on the Notice and notification by persons who wish to be considered interested parties for the purpose of the ECA negotiations will be on or before May 16, 2003.
DuPont Statement on ABC
"20/20" Segment on Teflon®
TV番組に対する反論
Instead of relying on the well-documented facts and the science
regarding the safety of Teflon® branded products, ABC has chosen to
accept on face value certain allegations and draw inappropriate
inferences from documents and events that are unrelated to the
safety of Teflon®.
In fact, ABC "20/20" failed to provide any new
information that would question the safety of Teflon® and
Stainmaster®.
Evidence from 50 years of experience and extensive scientific
studies supports the conclusion that Teflon® branded products and PFOA (also known as
C-8, a compound used to produce fluoropolymers, some of which are
sold under the Teflon® brand), do not cause any adverse human
health effects. In addition:
・ | The U.S. Food and Drug Administration said that Teflon® is safe for its intended use; |
・ | The U.S. Consumer Product Safety Commission (CPSC) denied a request from the Environmental Working Group (EWG) to consider warning labels for cookware. In a letter announcing its decision, CPSC told EWG that its petition did "not provide sufficient information" to support that non-stick coatings "have the ability to cause substantial injury or illness to a person through reasonably foreseeable handling or use." |
・ | The U.S. Environmental Protection Agency stated that it does not believe there is any reason for consumers to stop using any consumer or industrial related products ー as part of its investigation of PFOA. |
For 201 years, DuPont has lived
by a number of core values, including safety and high ethical
standards. The company has been open and forthcoming about all
aspects of the safety of PFOA and its use. We have consistently
reported information to our employees, to government officials
and to citizens of our plant communities. We adamantly deny any
allegations that we have acted improperly or unethically.
DuPont remains fully committed to the safety of its operations
and products. We recognize that the U.S. Environmental Protection
Agency (EPA) has questions about PFOA, largely based on the fact
that the "general U.S. population may be exposed to very low
levels of PFOA." We are working voluntarily with EPA and
others to address these questions. We would support EPA
regulations based on sound science, because this would confirm to
consumers that the products they use are safe for human health
and the environment.
It is important to note that while its review of PFOA is under
way, the EPA has said there is no reason for consumers to stop
using products.
We followed our practice of openness with the news media and
provided "20/20" with access to our experts and
facilities. We clearly stated our position and the facts on the
safety of PFOA to Producer Rhonda Schwartz and Reporter Brian
Ross on two separate occasions and provided supporting
documentation. These facts were ignored.
We would like to share the facts on several other subjects
discussed in the "20/20" segment:
Cookware Safety: Products sold under the Teflon® brand are safe
for consumers to use.
The U.S. Food and Drug Administration reviewed the safety of
cookware coated with DuPontTM Teflon® non-stick coating. Our products were
determined to be safe and have been approved for normal use in
the kitchen. In addition, the U.S. EPA, as part of its
investigation of PFOA, has said it "does not believe there
is any reason for consumers to stop using any consumer or
industrial related product."
In over 40 years of use, there have been billions of pots and
pans sold around the world that are coated with DuPontTM Teflon® non-stick coatings and we know of no
serious chronic or acute health problems associated with their
use. In conventional cooking situations, there is no coating
degradation and therefore, no potential exposure to polymer
fumes. At 500 degrees F, PTFE (non-stick coating for cookware)
would not emit any material that could be harmful to human
health. However, at this temperature, butter, oils and food will
begin to break down.
DuPont is aware of only one published incident of a pan left
unattended which resulted in a case of polymer fume fever in an
individual. The effects were temporary. Information on proper use
is available on www.teflon.com.
The Environmental Working Group (EWG) submitted a petition to the
CPSC asking the commission to enact a regulation requiring that
cookware with non-stick coatings, including Teflon® coatings,
"carry a label warning of the acute hazard the coating poses
to pet birds and humans." On June 27, 2003, the commission's
General Counsel declined to docket the petition, stating that
EWG's submission "does not provide information that shows
that these chemicals are released in amounts that would be
expected during a consumer's use of the product and that these
amounts would cause human illness or injury." EWG's request
was denied. DuPont fully agrees with the commission's
conclusions.
The claims made by the EWG are totally inconsistent with our
experience and the experience of hundreds of millions of
consumers around the world who use our products safely and
consistent with conventional kitchen use on a daily basisー thus deriving the convenience and
benefits provided by Teflon®.
Teflon®
Stain-Resist Textiles and Stainmaster® Carpet:
PFOA is not used to make Stainmaster® carpet or Teflon® stain-resistant textiles, nor is PFOA
used to make telomers, the ingredient to make soil, stain and
grease repellants for paper, apparel, upholstery and carpets.
Telomers are applied at very low concentrations to consumer
products such as carpet and apparel. Over 35 years of testing of
our chemistry and the commercial products it is applied to, we
have seen no safety concerns or health risks associated with our
use of DuPont telomer chemistry. There are some data that suggest
that trace amounts of PFOA may be detected in telomers.
Our studies indicate that PFOA is not easily absorbed through the
skin. In fact, PFOA has one of the lowest skin absorption rates
of any chemical that has been tested. Given the extremely low
potential for exposure from carpet or apparel, combined with
PFOA's low potential to be absorbed through the skin, there is no
potential significant exposure to PFOA from carpet or textile
products.
Consequently, we do not believe that contact with carpet or other
textile products represents a safety concern to consumers. The
U.S. EPA reached the same conclusion, stating that, as part of
its investigation of PFOA, it "does not believe there is any
reason for consumers to stop using any consumer or industrial
related product."
Reporting Birth Defects:
There is no
scientific basis to support the claims of two former DuPont
employees that the birth defects of their children were related
to PFOA. Our conclusions are
supported by extensive scientific and toxicological studies. In
addition, a 3M study monitoring pregnant employees exposed to
PFOA found no association between PFOA and birth defects.
We are confident that PFOA does not cause birth defects.
In summary, DuPont's 201-year heritage is based on our core values of safety, health and environmental stewardship; high ethical standards; and a commitment to treat all people with respect. These values are foremost in everything we do as a company. They apply uniformly across all of our businesses everywhere we operate in the world. We are committed to these values, both now and in the future.
DuPont Responds
to EPA Complaint, Denies Allegations
Company asserts it has complied with all laws and regulations
with respect to PFOA; will vigorously defend its position
http://www1.dupont.com/NASApp/dupontglobal/corp/index.jsp?page=/content/US/en_US/news/releases/2004/nr07_08_04a.html
DuPont today said
that it will file a formal denial to a complaint issued by the
U.S. Environmental Protection Agency (EPA) alleging that the
company failed to comply with the technical reporting
requirements of the Toxic Substances Control Act (TSCA) and the
Resource Conservation Recovery Act (RCRA) regarding PFOA. PFOA is
an essential processing aid used to produce fluoropolymers.
"DuPont has provided substantial information to EPA
supporting our conclusion that we have followed the law,"
said DuPont General Counsel Stacey J. Mobley. "We will take
action to respond to the Agency's complaint and will vigorously
defend our position."
"This is not about the safety of our products," Mobley
said. "It is about administrative reporting. Furthermore, we
believe that a decision against DuPont in this matter would
redefine TSCA and RCRA reporting requirements and would not
prevail under the scrutiny of the courts."
Noting that EPA has not proposed a specific penalty at this time,
the company said it will file a formal denial to the EPA
complaint within 30 days.
DuPont asserts that there is no legal basis for the EPA's
allegations. The company contends that it has fully complied with
statutory reporting requirements and disputes any association
between PFOA and harmful effects on human health or the
environment.
In April 2003, when it announced its review of PFOA, the EPA
stated that it does not believe there is any reason for consumers
to stop using any consumer or industrial related products while
its review is in progress. PFOA remains an unregulated compound.
"The evidence from over 50 years of experience and extensive
scientific studies supports our conclusion that PFOA does not harm human
health or the environment," Mobley said.
DuPont is a science company. Founded in 1802, DuPont puts science
to work by solving problems and creating solutions that make
people's lives better, safer and easier. Operating in more than
70 countries, the company offers a wide range of products and
