  The independent peer-reviewed study, sponsored by DuPont, concludes that the use of consumer articles with DuPont materials would not result in quantifiable exposure to perfluorooctanoic acid (PFOA). 

該獨立進行、並經獨立專家評審的研究得出以下結論：使用杜邦原材料的消費品，不會導致可計量的全氟辛酸銨（PFOA）接觸。

 DuPont initiated the study, conducted by Environ, an independent research firm, to better understand the potential for consumer exposure and to determine what risk there is, if any, from PFOA, also known as C-8.  PFOA is used as a processing aid in the manufacture of fluoropolymers, some of which are sold under the DuPont(TM) Teflon(R) brand.  It may be found at very low trace levels in some fluorotelomers products, which are used primarily to provide stain resistance to a number of textile products and grease-resistance to paper packaging.  DuPont is one of several companies globally that produce these materials.

該項研究由杜邦公司發起，由獨立研究機構Environ實驗室執行，旨在確實瞭解消費者接觸全氟辛酸銨（PFOA, 也被稱為C-8）的可能性，並評估潛在的風險。全氟辛酸銨（PFOA）是生產氟聚合物過程中的加工助劑。杜邦公司有些氟聚合物產品使用鐵氟龍®（Teflon®）註冊商標。目前只在一些氟調聚物（不同於氟聚合物）產品中發現有極少量的全氟辛酸銨（PFOA）殘留。氟調聚物產品主要用於一些紡織品的防塵處理和紙包裝材料的防油污處理。包括杜邦公司在內，全球有數家企業生產氟調聚物產品。

The study examined a wide variety of ways consumers could be exposed through common household products such as cookware and clothing, including through the skin, in the air, and orally.  All ages of consumers, from infant to adult, as well as adult trade professionals, were considered.  To assure accuracy and provide the most reliable test results, dozens of consumer articles were assessed using extremely conservative exposure models.  A peer-review panel, moderated by Dr. George Gray, executive director of the Harvard Center for Risk Analysis, evaluated the study to ensure its scientific rigor and validity.

此項研究關注多種消費者接觸全氟辛酸銨（PFOA）的途徑，包括通過皮膚、空氣和口腔接觸。各個年齡層的消費者都被考慮到了，從嬰兒到成人，包括專業人員。為保證精確性並提供最可靠和有效的檢測結果，研究人員採用極端的傳統接觸模式檢測了幾十種消費產品。專家評審會議由哈佛大學風險分析中心（Harvard Center for Risk Analysis）執行主任George Gray博士主持，對這一項目的科學嚴密性和正確性進行了評估。

“Cookware coated with Teflon(R) underwent rigorous scientific testing designed to see if any PFOA could be detected under exaggerated or extreme cooking conditions, and none was found,” said Dr. Jay Murray, a board-certified toxicologist and one of the three experts who provided peer consultation on the study.  “In fact, even when cookware coated with Teflon(R) was abraded [scratched] with a knife, no PFOA was detected.  Cookware coated with Teflon(R), along with other consumer articles that were tested, is safe and poses no health risks from PFOA.”  The results of this study are consistent with earlier studies by the China Academy of Inspection and Quarantine and the Danish Technological Institute that showed no exposure to PFOA from the use of non-stick cookware.

專家評審組由三位成員組成，其中之一經過美國國家認證的毒理學家Jay Murray博士說：“研究人員在誇張、極端的條件下對採用鐵氟龍®塗層的炊具進行了檢測，結果並沒有發現PFOA的存在。實際上，即使是用刀劃傷鐵氟龍®塗層，也沒有檢出PFOA殘留。無論是採用鐵氟龍®塗層的炊具還是其他消費品，都不會帶來由全氟辛酸銨引起的健康風險。”這一研究結果與不久前中國檢驗檢疫科學院以及丹麥技術研究所（Danish Technological Institute）的檢測結果是一致的，都證明使用不沾炊具不會導致接觸全氟辛酸銨。

The margins-of-safety for all articles tested ranged from 30,000 to over 9 billion, which dramatically exceeds the margins-of-safety of 100 to 1,000 typically used by regulatory agencies to judge the safety of chemicals.  “The study confirmed that the margins of safety calculated from the extremely low trace levels of PFOA detected on consumer end use articles are thousands of times safer than the margins of safety typically considered acceptable by regulatory agencies.  Based on results from the study, the use of the tested products would not result in quantifiable levels of PFOA in the blood,” said Dr. Robert Rickard, DuPont chief toxicologist. 

此次所有被檢產品的安全係數從三萬到超過九十億，遠遠高於任何管理機構用來評判化學品安全性的從100到1000的指標標準。杜邦公司首席毒理學家Robert Rickard博士說：“這次研究的結果證實了消費品中非常低的PFOA檢出量的安全係數，比管理機構所認可的安全範圍還要安全幾千倍。基於這一結果，使用受檢消費產品不會導致在血液中檢測到可計量的全氟辛酸銨殘留。”

As part of DuPont’s ongoing commitment to environmental stewardship and because questions on PFOA persist, the company already has made significant reductions in PFOA emissions from our manufacturing operations.  By year-end 2006, DuPont will have reduced emissions of PFOA in the United States by more than 98 percent.  DuPont, in cooperation with other major producers of fluoropolymers, has also announced that by year-end 2006, it will reformulate its dispersion products used for coating applications.  This move will reduce the potential for emissions at dispersion processors by more than 90 percent.  In addition, DuPont will reduce trace PFOA content in end-use telomer products by more than 85 percent, also by year-end 2006.

作為杜邦公司持續的環保努力的一部分，並且考慮到有關PFOA長殘留期的問題，杜邦公司已經採取措施大量減少了在生產過程中的PFOA排放。到2006年底，杜邦在美國的PFOA排放量將減少98%以上。杜邦公司還和其他氟聚合物生產企業共同宣佈，於2006年底前調整用於生產塗料的氟聚合物分散液的配方。這一工藝變化將把排放的可能性減少90%以上。此外，杜邦公司還將在2006年底前將調聚物產品中可檢測到的PFOA含量減少85%以上。
