致癌物在華盛頓的「政治遊說」

紐約時報

誰能想到致癌物在華盛頓也有自己的遊說團體?

不相信嗎?想想甲醛,一種在指甲油、廚房檯面、織物柔順劑和地毯等各種產品中都存在的物質。我們在自己家裡總會吸入甲醛氣體,主要是因為甲醛在建築材料裡面的應用。
還有一個事實你應當了解:根據官方科學家的說法,甲醛致癌。

化工產業則忙於反駁,企圖壓制這一科學共識,理由是他們擔心“公眾產生困惑”。很顯然,化工巨頭們擔心,一旦了解到甲醛會導致鼻癌和咽喉癌、可能還會導致白血病的話,你也許會感到困惑。

化工業的策略是遊說國會削減給《致癌物報告》(Report on Carcinogens)的經費。該報告厚達500頁,由美國國家衛生研究院(National Institutes of Health)每兩年公布一次,其中包含了關於致癌物的最權威信息。如果說化工業的做法聽起來像是斬殺信使的話,我得說,確實如此。

喬治·華盛頓大學(George Washington University)公共衛生學院院長林恩·戈德曼(Lynn Goldman)說,“自由市場運作的方式本來就是要讓大家掌握信息。但他們正試圖壓制信息。”

更大的問題在於,聯邦政府應當做公共衛生的看門狗,還是做行業的哈巴狗?當米特·羅姆尼(Mitt Romney)譴責奧巴馬總統過度監管的時候,命運攸關的正是這個問題。

2011年發表的最新一期《致癌物報告》中宣稱,“甲醛是已知的人類致癌物。”之前的版本僅將其列為可疑致癌物,但新報告援引了許多人體和動物暴露實驗的結論,認為已經不必再含糊其辭了。

化工業因此大發雷霆,因為他們正銷售大量的含甲醛產品,往往在人們不知情的情況下進入家庭。

根據加州能源委員會(California Energy Commission)2009年進行的一項調查,“幾乎所有家庭的甲醛濃度都超過了癌症及慢性刺激的指導水平。”

The Cancer Lobby

WHO knew that carcinogens had their own lobby in Washington?

Don’t believe me? Just consider formaldehyde, which is found in everything from nail polish to kitchen countertops, fabric softeners to carpets. Largely because of its use in building materials, we breathe formaldehyde fumes when we’re inside our homes.
Just one other fact you should know: According to government scientists, it
causes cancer.

The chemical industry is working frantically to suppress that scientific consensus — because it fears “
public confusion.” Big Chem apparently worries that you might be confused if you learned that formaldehyde caused cancer of the nose and throat, and perhaps leukemia as well.

The industry’s strategy is to lobby Congress to cut off money for the Report on Carcinogens, a 500-page consensus document published every two years by the National Institutes of Health, containing the best information about what agents cause cancer. If that sounds like shooting the messenger, well, it is.

“The way the free market is supposed to work is that you have information,” said
Lynn Goldman, dean of the school of public health at George Washington University. “They’re trying to squelch that information.”

The larger issue is whether the federal government should be a watchdog for public health, or a lap dog for industry. When Mitt Romney denounces President Obama for excessive regulation, these are the kinds of issues at stake.

“Formaldehyde is known to be a human carcinogen,” declared the
most recent Report on Carcinogens, published in 2011. Previous editions had listed it only as a suspected carcinogen, but the newer report, citing many studies of human and animal exposure to formaldehyde, made the case that it was time to stop equivocating.

The chemical industry was outraged, because it
sells lots of formaldehyde that ends up in people’s homes, often without their knowledge.

“Nearly all homes had formaldehyde concentrations that exceeded guidelines for cancer and chronic irritation,” according to a
2009 survey by the California Energy Commission.

The Report on Carcinogens also offended the chemical industry by listing styrene for the first time as “reasonably anticipated to be a carcinogen.”
Styrene, which goes into everything from boats to shower stalls, is mostly a risk to those who work in factories where it is used, so it’s less of an issue for the general public.

The chemical industry is represented in Washington by the
American Chemistry Council, which is the lobbying front for chemical giants like Exxon Mobil, Dow, BASF and DuPont. Those companies should understand that they risk their reputations when they toy with human lives.

The American Chemistry Council first got its pals in Congress to order a $1 million follow-up study on formaldehyde and styrene. Then it demanded, through a
provision drafted by Representative Denny Rehberg, a Montana Republican, that no money be spent on another Report on Carcinogens until the follow-up was completed — meaning a four-year delay until the next report. Stay tuned for an industry effort to slip some such provision into the next budget legislation.

Let’s be clear. There is uncertainty about toxic chemicals, and it is perfectly legitimate to criticize the Report on Carcinogens. But this effort to defund the report is an insult to science and democracy alike.

Barbara K. Rimer, the chairwoman of the
President’s Cancer Panel, told me that there might be ways to improve the Report on Carcinogens but that it would be wrong to cut off money for it. “Without this program, there would be a gap in the protection of the public,” she said.

Last month, 76 scientists wrote a joint
letter to Congress noting that the World Health Organization also listed formaldehyde as a known carcinogen, and styrene as a possible carcinogen. They defended the Report on Carcinogens as “consistent with international scientific consensus.”

“The American Chemistry Council is working to delay and ultimately destroy” the Report on Carcinogens, the scientists wrote.

The chemical council declined to speak to me on the record. It has a long record of obfuscation, borrowing the same strategies that the tobacco industry used to delay regulation of cigarettes.

“It’s the same playbook,” noted
Jennifer Sass, a senior scientist of the Natural Resources Defense Council.

The American Chemistry Council is also trying to undermine
scientific reviews by the Environmental Protection Agency. You can say this for our political system: Even carcinogens have an advocate in Washington!

The basic strategy is an old one. As David Michaels notes in his book “Doubt Is Their Product,” the first evidence that asbestos causes cancer emerged in the 1930s. But three decades later, industry executives were still railing about “ill-informed and exaggerated” press reports, still covering up staggering cancer rates, and still denouncing regulation of asbestos as “premature.” Huge numbers of Americans today are dying as a result.

Do we really want to go through that again?
