But Robin Mackar, a spokeswoman for the National Institute of Environmental Health Sciences, which oversees the reproductive center, said Sciences International "has worked for the center since 1998 without any problems" and has participated in reports on 17 chemicals.
"These contractors have no decision-making or analytical responsibilities," she said.
But according to company and government websites and Federal Register documents, Sciences International is involved in management and plays a principal scientific investigative role at the federal center. The company has a $5-million contract with the center, according to an NIEHS document.
"The most significant project at our firm is the management of the National Toxicology Program's Center for the Evaluation of Risks to Human Reproduction," the Sciences International website says. It says half its clients are from the private sector, but its health studies are independent and it "is proud of its reputation for objective science."
Its current website contains no list of industry clients. But a 2006 version names BASF and Dow Chemical -- which manufacture the plastics compound BPA -- as well as DuPont, Chevron, ExxonMobil, 3-M, Union Carbide, the National Assn. of Manufacturers, and 45 other manufacturing companies and industry groups.
In 1999, Sciences International represented R.J. Reynolds Tobacco Co. in fighting an Environmental Protection Agency proposal to regulate a pesticide used on tobacco crops. In 2004, its vice president, Dr. Anthony Scialli, who is identified as the federal center's "principal investigator," co-wrote a study with a Dow Chemical Co. researcher on how to extrapolate data from animal tests to humans.
In addition, another Sciences International employee who works at the federal agency, Gloria Jahnke, has collaborated nine times on chemicals research with another company that gets funding from the plastics industry, according to a Times review of medical publications.
Sciences International's president boasted about its close collaboration with the federal reproductive health center, as well as the EPA and other federal agencies, in a letter soliciting R.J. Reynolds as a client in 1999.
Signed by company founder Elizabeth Anderson, the letter stated that Sciences International "serves the private sector, including many trade associations, on a wide range of health and risk assessment issues. However, we are different from most other consulting firms in that we also currently serve government agencies," which, the letter said, gives the company "a unique credibility to negotiate with regulators on behalf of our private sector clients."
