Target: Gina McCarthy, Administrator of the U.S. Environmental Protection Agency
Goal: Urge government regulators to reassess safe intake levels for humans of BPA and its alternative.
Many reusable water bottles bear the label “BPA-Free,” meaning that it is free of the chemical BPA, known to disrupt hormone function. Yet, Bisphenol S, the popular alternative to BPA, has endocrine-disrupting effects equal to those contained in BPA, according to a recent article in the LA Times. Push to recalculate safe levels of exposure to these chemicals.
BPA and Bisphenol S may interfere with the development of the part of the brain that influences fear, impulse-control, obesity and early puberty, according to the LA Times article. Even low-level exposures were found to alter the timetable and rate of development, which could cause the brain to “wire itself incorrectly,” leading to “potentially subtle, but wide-ranging” effects on behavior.
The new research in addition to several past studies on BPA’s endocrine-disrupting effects point to the second trimester as a time when the fetus is particularly vulnerable to BPA. Thus, the study suggests that pregnant mothers limit their exposure to plastics and receipts—products still commonly containing BPA.
Yet, the range of effects that different exposures had remains a cause for concern. Moderate doses did not have a significant impact on neurological development, and high doses overwhelmed biological defense systems, causing damage. Low doses, however, were found to mimic naturally occurring hormones, which could actually increase the risk of cancer, infertility, and other endocrine disorders. The problem is that during testing, government regulators start at higher doses and work their way down to lower ones. They tend to stop when physiological effects of exposure are not detected, meaning a risk at low exposure might also go undetected.
By signing the petition below, you can show your concern about this new evidence and express support for greater research to determine the real risk of exposure to BPA and its alternative, Bisphenol S.
Dear Ms. McCarthy,
I am writing in order to bring your attention to recent research showing BPA and its alternative to have hormone-disrupting effects. While the dangers of high exposure to these chemicals is well-documented, this research suggests an even greater challenge for regulation: At low-levels, the chemicals seem to mimic naturally occurring hormones, increasing risk of cancer, infertility, and other endocrine disorders.
I urge you to lead the way in recalculating safe levels for exposure to these chemicals for humans. It is my sincere hope that this step may protect the health of the public and prevent more widespread and severe illness down the line. Taking action now can help our communities know how to protect their loved ones and themselves from harm.
