The way the tests work today is we think that by testing at high doses we’re gonna see everything. So that once we get to a dose that’s intermediate and we don’t see anything, we’re golden.

But the science is telling us that at really low doses as contaminants mimic hormones. They can have effects that are totally unpredictable by what happens at high doses.

Pete Myers spoke to Living on Earth about the consequences of current testing.

Suzanne Condon, director of the state Bureau of Environmental Health, said this in the absence of any federal action on the chemical:

We are concerned about this enough that we want to warn the public. It just seemed it wouldn’t be appropriate for us to sit back and not do anything.

The FDA has yet to change their policy on the chemical in food contact materials. Instead, there has been enough demand from consumers that BPA has been removed from many brands of baby bottles and sippy cups. Also, some states and municipalities have banned BPA, so it’d be pretty tough for manufacturers to regionally offer products with different chemical compositions.

Here are the places where BPA has been banned:

So what’s the big deal? They’re endocrine disruptors, which means they interfere with the normal functions of hormones. Phthalates have been linked to early onset of puberty in girls, obesity, lower sperm count and testosterone level, under-virilized boys, and male genital deformities such as hypospadias (in which the urinary opening is located somewhere besides the head of the penis, like the underside). Whee!

And now they’ve been linked to preterm birth. Makes you wonder if we should kick the chemical out of all products, doesn’t it?

The group is concerned over bisphenol-A and similar hormone-disrupting chemicals, found in plastics, pesticides, and other products. It said in a statement that bisphenol-A is a

’significant concern for public health’ and that it’s important for consumers to take a ‘precautionary approach’ to limit their exposure.

This follows on the heels of a few more studies regarding BPA. First–and most worrisome–is the recent study that showed that human exposure to BPA is likely much higher than previously thought and much higher than deemed “safe” by the FDA. That study’s author, Dr. Frederick vom Saal, who presented his study’s findings at the Endocrine Society’s annual meeting, said of the chemical:

BPA is now known to be a potent estrogen.

Human and animal studies indicate it could be related to diabetes, heart disease, liver abnormalities, miscarriage and other reproductive abnormalities, as well as prostate and breast cancer

Other recent studies should have us all cutting out the polycarbonate plastic.

This study shows how a low-dose exposure to two types of commonly found phthalates has a profound effect on bone cells. Based on the results, long-term exposure to phthalates could have devastating effects on developing bones in young bodies and accelerate deterioration in aging bones. Estrogen deficiency is responsible for a number of bone diseases such as osteoporosis. For this reason, many are concerned about the effects of phthalate exposure on bone health.

Phthalates are plasticizers which are used to add flexibility to plastics. It has been the common ingredient in everyday items like food containers, baby bottles, and packaging for beauty products. Known as as a reproductive or endocrine disruptor; it is slowly being phased out by United States and European nations, but unfortunately, not quickly enough. Even more dangerous is the fact that Phthalates are used in a large variety of products including children’s toys. “Phthalate use is widespread. Phthalates are commonly found in household items made of plastics and in health and beauty products.  Some products with phthalates include toys, vinyl flooring, plastic medical tubing, shower curtains and personal care products such as shampoo, hair sprays and detergents.”

Bisphenol-A has been linked to early onset of puberty, low sperm count and infertility, and its carcinogenic effects may include breast cancer. It has also been linked to heart disease and diabetes. You’ve heard all of this, I’m sure.

But how ’bout this? Bisphenol-A was first developed as a synthetic hormone. It’s an endocrine disruptor. It affects our children. It affects our adults. And the FDA still refuses to require removal from food contact materials?!

Shanna Swan, a professor at the University of Rochester School of Medicine and Dentistry, authored a study recently, testing 106 expecting mothers’ urine for pthalates. They also looked at their babies at 12 months old, and found a correlation between the levels of pthalates in the mother’s body and certain physical traits, such as undescended testicles, smaller penis, and immature genital development.

Phthalates are an endocrine disruptor found in many everyday items, from PVC shower curtains to furniture to personal care products. Endocrine disruptors are seen by the body as hormones, and interfere with normal development, starting in the womb. If a male baby is exposed to something that lowers testosterone through interference, proper reproductive system growth doesn’t happen.
