“Peer reviewers should be free to say whatever they think, and<br />

to have retroactive retaliation sends the message that if you say<br />

something unpopular with EPA, your views may get dropped.”<br />

ethers (PBDEs). The review <strong>of</strong> this group<br />

<strong>of</strong> flame retardants began in 2002. The European<br />

Union and several U.S. states have<br />

banned penta-BDE and octa-BDE. The<br />

main BDE found in commerce in the U.S. is<br />

deca-BDE, which is incorporated into plastics<br />

in the housings <strong>of</strong> television sets and<br />

other electric and electronic equipment, as<br />

well as upholstery for furniture and other<br />

items.<br />

The peer review panel examined EPA’s<br />

draft assessment <strong>of</strong> BDEs, which includes<br />

agency expert judgments on how much<br />

exposure to each BDE is<br />

safe. These judgments<br />

can have far-ranging<br />

regulatory effects.<br />

EPA places its peerreviewed<br />

judgments on<br />

safe doses <strong>of</strong> chemicals<br />

and the scientific justification<br />

behind them<br />

in a database called the<br />

Br<br />

Br<br />

Br<br />

Br Br<br />

Integrated Risk Information System,<br />

which is available on the Web. EPA, other<br />

federal agencies, state environmental<br />

departments, and even regulators in foreign<br />

countries rely on the database. For<br />

instance, they <strong>of</strong>ten depend on the database’s<br />

safe daily dose numbers to decide<br />

how much cleanup a polluter must do at a<br />

contaminated site.<br />

Rice is a world-class toxicologist, according<br />

to several toxicologists interviewed<br />

by C&EN, some <strong>of</strong> whom are associated<br />

with EPA and did not wish to comment<br />

publicly. She was a toxicologist with<br />

Health Canada and the U.S. EPA’s National<br />

Center for Environmental Assessment,<br />

which is conducting the PBDE review.<br />

Rice declined to comment to C&EN, as<br />

did EPA <strong>of</strong>ficials.<br />

Rice was selected for the peer review<br />

panel in 2006 and was one <strong>of</strong> five reviewers.<br />

The panel met in February 2007 and<br />

issued its assessment in mid-March, when<br />

EPA posted the report on its website.<br />

On May 3, 2007, ACC wrote to George<br />

M. Gray, EPA assistant administrator for<br />

R&D, complaining about “the appearance<br />

that [the] peer review panel’s leadership<br />

might lack the impartiality and objectivity<br />

necessary to conduct a fair and impartial<br />

O<br />

Deca-BDE<br />

review <strong>of</strong> the data.” Rice, the letter says,<br />

had testified before the Maine State Legislature<br />

on behalf <strong>of</strong> a state agency, the<br />

Center for Disease Control & Prevention,<br />

where she works. There, she advocated a<br />

phaseout <strong>of</strong> deca-BDE.<br />

Rice simply conveyed the policy position<br />

<strong>of</strong> her employer to state lawmakers,<br />

says Sonya Lunder, senior analyst with the<br />

Environmental Working Group, a nonpr<strong>of</strong>it<br />

advocacy and research organization.<br />

In a Jan. 8, 2008, letter to ACC, Gray<br />

announced that the agency had removed<br />

all <strong>of</strong> Rice’s comments<br />

Br Br<br />

Br<br />

Br<br />

Br<br />

from the final peer review<br />

report. The agency had<br />

redacted her comments<br />

from the report and reposted<br />

it to the website.<br />

In his Jan. 8 letter,<br />

Gray said his letter was<br />

a follow-up to a June 15,<br />

2007, meeting with ACC<br />

to discuss Rice’s involvement. Gray wrote<br />

in his letter that EPA made the changes<br />

because “one <strong>of</strong> the panel members had a<br />

potential conflict <strong>of</strong> interest.”<br />

At ACC’s urging, Gray said he had also<br />

reviewed initial and final comments <strong>of</strong><br />

other panel reviewers to determine if the<br />

chairwoman had influenced their views.<br />

His review found “minor additions” from<br />

reviewers but provided no evidence that<br />

Rice had “significantly influenced the other<br />

panelists.”<br />

Rice “has no conflict <strong>of</strong> interest that<br />

I’m aware <strong>of</strong>,” says Merrill Goozner, director<br />

<strong>of</strong> the Integrity in Science project at<br />

the watchdog group Center for Science<br />

in the Public Interest. Under federal laws<br />

and policies for advisory panels, conflicts<br />

<strong>of</strong> interest have to do with advisers’ potential<br />

financial gain or loss from their<br />

recommendations.<br />

Goozner’s group and environmental<br />

organizations regularly write letters to EPA<br />

contending that external peer reviewers<br />

have financial conflicts <strong>of</strong> interest. “ACC<br />

has every right to write a letter to EPA,<br />

just like we do,” he tells C&EN. It is the<br />

agency’s job, Goozner says, to investigate<br />

the situation and determine if a reviewer<br />

indeed has a conflict.<br />

EPA, however, “made the wrong decision”<br />

in Rice’s case, Goozner says.<br />

“Apparently, EPA didn’t want to hear<br />

from this person because industry disagreed<br />

with her conclusions,” says David<br />

Michaels, a pr<strong>of</strong>essor <strong>of</strong> environmental and<br />

occupational health at George Washington<br />

University.<br />

Michaels, former Department <strong>of</strong> Energy<br />

assistant secretary for environment, safety,<br />

and health, says the removal <strong>of</strong> Rice from<br />

the panel is consistent with other actions<br />

the Bush Administration has taken to stack<br />

advisory groups with scientists favorable to<br />

its views and to silence opponents.<br />

LUNDER AND other scientists interviewed<br />

by C&EN warn <strong>of</strong> the chilling effect Gray’s<br />

actions may have on other scientists asked<br />

to take part in peer reviews. They note that<br />

Rice had already been vetted and selected<br />

by EPA and the contractor that put together<br />

the panel.<br />

“Peer reviewers should be free to say<br />

whatever they think,” Lunder says, “and to<br />

have retroactive retaliation by removing<br />

your name sends a message that if you say<br />

something unpopular or out <strong>of</strong> line with<br />

EPA, your views may get dropped. It challenges<br />

the whole principle <strong>of</strong> review by an<br />

unbiased panel without fear <strong>of</strong> retribution.”<br />

In a statement released earlier this<br />

month, ACC said its “strong support for<br />

science” and “an independent peer review<br />

process” led it to raise concerns with EPA<br />

about Rice’s membership on the PBDE<br />

panel. “We believe EPA acted appropriately<br />

and consistently with the rules governing<br />

membership in scientific review panels,”<br />

the industry group said.<br />

“ACC will work with the Energy & Commerce<br />

Committee to provide it with the<br />

requested materials pertaining to this<br />

matter,” the statement said.<br />

The final toxicological human health<br />

assessment <strong>of</strong> PBDE is expected this<br />

month. It is now being examined by the<br />

White House’s Office <strong>of</strong> Management<br />

& Budget, according to EPA <strong>of</strong>ficials. An<br />

<strong>of</strong>ficial familiar with the draft said Rice’s<br />

toxicological studies are cited in the assessment<br />

although her views on the draft<br />

had been struck. ■
