The Real Story Behind Bisphenol A

By: David CaseWed Jan 14, 2009 at 1:45 PM
How a handful of consultants used Big Tobacco's tactics to sow doubt about science and hold off regulation of BPA, a chemical in hundreds of products that could be harming an entire generation.

Sciences had also built a robust practice helping corporations grapple with lawsuits and regulation. Among its clients were law firms, trade associations, and oil-, tobacco-, and chemical-industry giants. Until 2006, Sciences reported on its Web site that it had defended MTBE (a gasoline additive since banned in 25 states), TCE (an industrial solvent in drinking water found highly likely to cause childhood cancer and birth defects), and perchlorate (another toxin in drinking water that California has deemed "a serious threat to human health"). Tools of the trade included providing expert testimony in lawsuits and producing scientific papers for publication.

A 2005 investigation in Environmental Health Perspectives raised questions about the boundaries that Anderson and her firm were willing to cross in service of their clients. The journal focused on Sciences' defense of the pesticide phosphine. In the late 1990s, the EPA proposed stricter standards for phosphine after several people died near fumigated warehouses. The tobacco industry determined that the restrictions would cost millions and turned to Sciences for help. Correspondence between Anderson and R.J. Reynolds, obtained from the UC San Francisco tobacco archives, reveals that Anderson lobbied her former colleagues at the EPA to reconsider. Then, with input from her clients, she drafted a report arguing for the old standards and offered to get it published in a peer-reviewed journal. "My experience is that consultant reports funded by those being regulated, and written expressly for the EPA, are easily and frequently ignored," she wrote in a memo to Joel Seckar, a toxicologist at R.J. Reynolds. "Since I am currently editor-in-chief of the international journal Risk Analysis, perhaps the peer-review process could be expedited." For this, "Sciences would need an additional $35,000 over and above the $50,000 provided by the original contract," the letter concluded. When the EPA eventually decided not to change the exposure standard for phosphine, the agency cited the review by Sciences International as justification. (Risk Analysis's board -- which included HCRA's George Gray -- later tightened its conflict-of-interest standards, after examining the Sciences-phospine episode, but allowed Anderson to remain editor. Anderson declined to talk with Fast Company about the matter.)

Among the first tasks in Sciences' examination of BPA was to draft a review of previous studies. That draft would serve as a foundation for a panel of scientists who would judge the compound. According to biologist Pete Myers, chief scientist of the nonprofit Environmental Health Sciences, who analyzed the 330-page report, it shared flaws with the discredited Harvard review. "They contained similar biases, both giving undue weight to flawed industry studies and dismissing a wealth of research funded by the National Institutes of Health," he says. In its own investigation, the Environmental Working Group, a D.C.-based consumer advocate, found that the Sciences draft failed to note which studies were industry funded and ignored details such as Tyl's use of the estrogen-resistant CD Sprague-Dawley rat.

A further complication was that the panel of experts brought in to conduct the review itself -- while all highly accomplished in their own specialties -- included only one person with any experience in BPA research. Unfamiliar with the thousands of pages of literature, the panel was heavily dependent on the Sciences draft review, says Myers. In November 2007, the panel issued a weak warning on BPA: that the research merits "minimal concern" for most of the effects studied.

The fact that the National Toxicology Program eventually overruled the panel -- strengthening the warning to "some concern" -- has much to do with outrage in Congress over revelations that Sciences International had a significant conflict of interest. In February 2007, another investigation by the Environmental Working Group had revealed that Anthony Scialli, a top Sciences employee whose title was "principal investigator" under the 2005 CERHR contract, had coauthored a 2004 study on birth defects from chemicals with a toxicologist from Dow, a manufacturer of BPA. In response, Senator Barbara Boxer and Representative Henry Waxman, both of California, wrote letters upbraiding NIH brass and vowing to keep a close eye on the BPA panel. The NIH requested an explanation from Sciences, which denied that any conflicts had "impaired its judgment or objectivity."

This is a really well written article. I was so glad to have had my children about 10-15 years later than most of my peers because of what we have learned in the last few years about environmental chemicals in bottles as well as disposable diapers. (I'm in my late 30s, currently have a 14 month old & am 6 months pregnant with Baby 2)

Many of my friend's children have learning disabilities, ADHD, Diabetes, Autism, etc. & I believe most of these problems could have been brought on by chemicals in the environment. I went out of my way to find BPA free bottles (Avent) and use cloth diapers, among other precautions including buying organic foods. It is true what the article says about chemicals being safe until proven dangerous & my father suffers from exposure to Agent Orange but it took many years to prove it & get Monsanto to take responsibility for that mess.

Anyway, thank you for the article. I am currently sharing it with verious Mommy groups & family memebers.

I agree that this article is well researched, but I disagree that it is well written. The authors are just as overtly advancing a point of view as the people thy are accusing of misleading the public. They take huge liberties with the interpretation of the facts. They find every study that indicates BPA is a hazzard to be very good science and every study that indicates BPA is not a grave concern to be terribly flawed. Hmmmm? Is it likely to be this binary? I think not.

I used to work as a scientist for one of the plastics companies mentioned in the article. I did a lot of research on BPA and polycarbonate. I am 10 years removed from plastics related companies and have zero financial stake in the outcome of any BPA related gevernment actions. My opinion is strictly based on my experience in the industry and my knowledge of the facts.

BPA may be a hazzard to some degree. I don't think we know enough to quantify it. Any compound, naturally occuring or synthetic, can be hazzardous under certain conditions and/or above certain threshold levels. Arsenic is a well known poison, yet in trace amounts is beneficial in the human diet. I could easily write an article as hysterical as this one about arsenic, never mentioning the benefits.

Polycarbonate is the major end product from BPA. The use of polycarbonate as a packaging material has greatly improved human health in so many ways, including the safe delivery of food and beverage products that otherwise may be subject to many forms of contamination, it's use in medical instruments and devices, and as a lens material for vision care products. Polycarbonate is returnable, reusable, and recyclable. Because of its heat resistance, it is sterilizable by autoclave. Few other packaging products are this versatile with respect to applications and to limiting packaging waste products going into landfills. For example, PET bottles (aka Coke bottles) have a low heat resistance and cannot be sterilized and reused. Some get recycled into fleece products but that process is not cost effective, so most end up in landfills.

We must weigh the risk/reward ratio of decisions about materials such as BPA derived plastics. What are the benefits of the materials, what are the viable alternatives, etc? The trace amounts of benzene in unleaded gasoline are known to be carcinogenic. We inhale those every time we fill up our tanks. However, the alternative is leaded gas and no one wants that. There are no risk free solutions. It's about managing risk when all the facts are not obvious. Equating the risks of BPA with dioxins, agent orange, and tobacco is hyperbole and disingenuous. The body of data in those fields is huge and the effects are documented in human health data, not extrapolated from limited, and by the author's own admissions, sometimes questionable laboratory results. We do ourselves a disservice if we let hysteria drive our decision making processes.

I would beg to differ with Mr. Williams, while a plastic over the years may have been found to be a wonderful packaging material, it does not mean it is a safe material under certain conditions. Could it be that hot milk in a plastic bottle pulls more of a harmful compound into the milk and could it just be the cause of increased autism in children. After all heating milk or formula in a plastic bottle in a microwave was not too common 30-40 plus years ago. Christina get glass bottles for your little ones and lets all push for more reserach into the use of some of these plastics and their compounds that leach into our foods.

January 28, 2009 at 4:39pm by Trevor Butterworth

This article is shockingly misleading about the science. One might expect any article that presented itself as the "true story" of BPA *not* to leave out the European Union's risk assessment of the chemical completed in 2006 and updated in 2008 - particularly as the EU legislates according to the Precautionary Principle. Conducted by 21 independent scientists across the EU for the Food Safety Agency, it concluded BPA was so safe the tolerable daily intake could be increased by a factor of five. It also repeated the salient point noted in every risk assessment, whether by the Japanese Government or the U.S.'s CERHR - oral ingestion of BPA eliminates all estrogenic capacity.

In other words: BPA is not an endocrine disruptor if orally ingested. As oral ingestion is the primary route of exposure for humans, studies that posit a risk based on IV exposure have repeatedly been rejected by risk assessments, whether independent, government or industry funded.

I also searched for mention of NSF International's risk assessment of BPA, which was published last year, and found nothing. NSF is a non-profit consumer investigation group - it's results are broadly in line with the EU. In fact, all the risk assessments are broadly in line with each other.

Mr. Case also seems unaware of such multigenerational studies on low dose exposure to BPA, conducted by the EPA, Howdeshell et al (2007), which appear to throw a wrench into the low-dose exposure thesis. And he also seems to discount Ashby's attempts to replicate Vom Saal's work (he failed) and the National Toxicology Program's biostatistics panel criticism of Vom Saal's data.

Instead of a dispassionate investigation of the science, the author seems determined to paint a conspiracy. He has gone to all the people who have a vested interest in pushing BPA as toxic line (research grants, lifetime's work etc), and given the other side - which happens to include some of the world's leading toxicologists no credence whatsoever.

I declare that I have no financial interest in BPA or the chemical industry in declaring this article a disgrace.

Bravo to David Case and Fast Company for having the courage to bring to light another example of failure from the last administration - the deregulation of the chemical industry, as demonstrated by the terrible situation with bisphenol A. Still yet another new study came out this week demonstrating that bisphenol A remains in our bodies longer than anyone previously believed, and is difficult to get rid of, perhaps storing itself in our fat. And with previous studies demonstrating links of BPA exposure to obesity, how convenient! The concept of "self regulation" has resulted in rising rates of illness linked to chemical exposure - including cancer and neurodevelopmental problems with children. The era of public apathy with corporate arrogance toward our health is ending. Even the EU and Canada are set to impose restrictions on BPA - so we won't be able to sell products with this stuff with our trading partners in the global marketplace. With so much scientific study on this chemical, one would wonder why its makers don't just take the money they spend on their spin doctors who attack scientists and lobbying firms who influence legislators and who also try to interfere with regulatory policy and use it to develop safer products? They'd be better off in the competitive marketplace and we'd be safer from illness linked to exposure from their chemical.

Thanks to Fast Company and to David Case for writing a very well researched and thorough article. This isn't the first time that the chemical industry has been exposed for creating controversy in the interest of maintaining a market for their product. Last year, Representative Dingell launched a probe into the influence of industry at federal agencies such as the EPA and FDA. And Congress is still taking note, with bills poised be introduced in both the House and Senate that will ban BPA.
The Natural Resources Defense Council (NRDC) has also been paying attention to this issue and has filed a petition with FDA asking them to revoke their approval of BPA as a food additive.

Thank you for writing such a thorough well-researched story on bisphenol A (BPA).

Bisphenol A is a dangerous toxic chemical that’s been found to cause harm by over 100 independent scientific studies. It’s a shame the chemical industry continues to defend this unnecessary toxic chemical when safer substitutes are available.

Most recently, three new studies found that:
· According to a Reuters story, “A controversial chemical used in many plastic products may remain in the body longer than previously thought, and people may be ingesting it from sources other than food, U.S. researchers said on Wednesday.”
· According to Environmental Health News, “In this first study examining infants’ exposure to bisphenol A, premature babies hospitalized in neonatal intensive care units had levels of BPA in their urine 10 times higher than the general population. The source of exposure most likely was plastic medical devices used in the hospital, although some could have come from infant formula.”
· Also according to Environmental Health news, “scientists estimate that the amount of bisphenol A (BPA) circulating in the blood of babies is more than 11 times higher than the amount in adult blood. The striking disparity is most likely due to natural differences in metabolism and body size between babies and adults. This study points to the need for chemical exposure standards to better incorporate differences in vulnerabilities between children and adults.”

Thank you again for shining the light on BPA.

January 30, 2009 at 12:03am by Frederick vom Saal

Trevor Butterworth makes numerous statements in his response to the article by David Case about bisphenol A (BPA) that are directly contradicted by scientific findings in peer-reviewed published studies. First, Mr. Butterworth stated that: “studies that posit a risk based on IV exposure have repeatedly been rejected by risk assessments”. In direct contrast to this statement, my colleagues and I published an article showing that in newborn mice, it made absolutely no difference whether BPA was fed to the babies or administered by injection (Taylor et al. 2008), since newborn mice, similar to newborn humans, have very limited capacity to metabolize BPA or any other chemical or drug, as any parent knows. Furthermore, acknowledging this fact, the Center for the Evaluation of Risk to Human Reproduction (CERHR) within the National Toxicology Program (NTP) concluded that route of administration was irrelevant in studies involving babies, so apparently Mr. Butterworth did not really read the CERHR report released in September 2008 that he cites. He also appears not to have read the article that he cites from the EPA, which was not a multigenerational study. Mr. Butterworth’s lack of knowledge regarding the actual facts in the articles in cites is disturbing given the harsh tone of his critique. Second, in adult men and women, as the length of time since last consuming food and beverages increases, according to Mr. Butterworth there should be a dramatic decrease in BPA, yet virtually no decrease in BPA occurs (Stahlhut et al. 2009). Third, the conclusion from a huge number of peer-reviewed published studies with animals directly contradicts the statement by Mr. Butterworth that: “oral ingestion of BPA eliminates all estrogenic capacity. In other words: BPA is not an endocrine disruptor if orally ingested.” In addition, the finding from data collected by the Centers for Disease Control and Prevention as part of the United States National Health and Nutrition Evaluation Survey (NHANES) that as BPA levels increase in people they are at greater risk of type 2 diabetes and heart disease also directly contradicts Mr. Butterworth’s assurance that BPA is completely safe (Lang et al. 2008). Finally, in Europe the risk assessment of BPA by the European Food Safety Authority (EFSA), which used the same flawed approach of only relying on 2 chemical-industry funded studies to reach its conclusions, will be re-evaluated at a meeting in Berlin in March 2009. One reason for the re-evaluation is that 36 internationally recognized scientists co-authored a peer-reviewed published critique of the US FDA and EFSA decision-making process that led these agencies to exclude from their evaluation of BPA findings contained in hundreds of peer-reviewed articles published by scientists not associated with chemical corporations (Myers et al. 2008). Mr. Butterworth works at STATS, which presumably is an “independent” organization. However, readers will find that they typically assure the public that chemicals such as BPA are not dangerous, regardless of the scientific evidence. The inaccurate statements by Mr. Butterworth about the safety of BPA are reminiscent of similar statements about the safety of cigarette smoke made by product-protection organizations discussed by David Case in his article on BPA. I expect that readers of Fast Company are astute enough to recognize attempts to mislead the public about the hazards of products that generate billions of dollars in profits for a few corporations.

This may be my favorite article of the last year in any venue. My favorite tea comes in plastic bottles with a '7' in a triangle on the bottom. I wrote the manufacturer asking them to reassure me that their bottles didn't contain BPA as I was told that '7' was its marker. They responded by sending me a handful of coupons. Not one word about BPA. It's too bad, I really liked that tea.

Robert Williams states that "equating the risks of BPA with dioxins, agent orange, and tobacco is hyperbole and disingenuous." As a chemical engineer and patent attorney with significant hormonal pharmaceutical experience, I strongly disagree. In fact, based on the widespread use of BPA in the United States, the risk from BPA may far exceed that of dioxins/agent orange, and possibly even tobacco, which mainly only affects the user.

The new study referred to by Stephenie Hendricks intrigues me, as I have been searching for a mechanism to explain a number of related cancers (breast and prostate), miscarriages/birth defects, and asthma in my former neighborhood. I primarily looked at two major pollution sources -- a large waste oil burning asphalt plant suspected of dioxin, PCB, cadmium, and formaldehyde emissions -- and an incinerator ("waste to energy" facility). The latter of these would be more prone to BPA emissions, because as polycarbonate polymer in trash is thermally broken down, the monomer, BPA, may be freed from its polymeric state, and would then be made bioavailable. It could then be transported as part of particulates emitted from a stack, or in collected fly ash, which may disperse to some degree after collection if not properly handled. When particulates and ash are inhaled, BPA could enter the blood stream via the lungs (thus the recent heightened concerns about PM2.5 particulates). Since BPA is bioactive on the microgram level, it would not take much inhaled BPA to have a significant effect.

Such a mechanism could have even more significant effects in rural areas, where low temperature combustion of trash via burn barrels, including burning of BPA containing cans and bottles, is widespread.

I would appreciate any comments on an airbourne BPA uptake mechanism, especially from Professor vom Saal, whose work I have found to be very insightful.

What I found most striking is not that (some)companies will go to great lengths to hold on to profitable chemicals but the lack of countervailing power from government agencies which are to weak, underfunded and unsophisticated to recognize a wolf in sheep's clothing.

Well done Fast Company! I've worked on chemical policy for many years and folks are definitely trying to "do a tobacco" on BPA and other ubiquitous chemicals. If we spent the money the industry folks layout in lobbyist and lawyers fees on alternatives, we could have solved this conundrum years ago. I hope to see regulation and innovation go on parallel paths to ending the use of something that could be hurting kids and developing safer alternatives at the same time. We can do better and we should. A better system would look for those compounds that have the least potential for harm being preferred, not waiting for harm to be proven by the companies selling the chemical in question. The current system basically says, until their is a body count, we won't regulate. We are smarter than that. Hopefully a new administration will have better science and oversight of the agencies regulating potentially harmful chemicals. In the meantime, let the alternatives be made widely available and the market work its magic.

This is so hysterical! All of these stupid, lazy women fretting over their baby’s health being at risk. If they really cared about their baby’s health they would have breastfed in the first place. They would not even be in this situation if they would have done the single most natural, loving, healthy and easy thing and just nursed. There is SO MUCH education out there about how babies should be breast fed for at least the first year of life and these dumb women still choose to ignore it. I feel so sorry for all the poor babies that are born to these ignorant, lazy women. I work full time and I pumped for 18 months. The bottles that came with my breast pump have always been BPA free (Medela). Even if they were not already BPA free…BPA only leeches into food/liquid at extreme temperatures…like in the microwave. Who would microwave anything for a baby in the first place? Microwaves DESTROY nutrients in breast milk so it is not ever exposed to extreme temperatures. Good nursing mothers have never placed their babies in harm even if they did use bottles that had BPA in them. It official, nursing mothers really do love their babies more are better mothers than women who formula feed.

BPA: The real story from the “Canary in a Coal Mine” …

I’m a chemist and now entrepreneur (I think…) who has worked with Bisphenols during my thirty-year career- making them and putting them into products. Unfortunately any possible hormonal effect on me has been confounded with my age and baldness- except for maybe learning impairment…

A great article especially the Product Defense Intrigue and I would like to add to it.
The real “burden of proof” lies with the consumer and CEO’s for scientific literacy- maybe “Science for Dummies”, companies for values and ethics, and the government for judgment to hold everyone accountable for their liberties and opportunities given to them.

If one was to see how bisphenols are made, one would question immediately making metric tons of BPA to say the least of putting this stuff or incorporating into polycarbonate, epoxides etc. Into baby bottles- hey they even put bisphenols into inks and papers maybe the magazine I’m responding to.

The reality is management of chemical risk/benefit is extremely complicated. Are there opportunistic folks and wrongdoers, of course!

We need to educate not regulate and hold those accountable for their wrong actions

As for me, I will try to make money as a chemist (Even the guy who discovered Lipitor was “impacted “ or let go in more understandable terms), maybe buy me a hat and a crossword puzzle, for my baldhead and bad memory.

If these low-dose findings were counterintuitive to toxicologists, they made perfect sense to developmental biologists. After all, BPA is a synthetic hormone.
