Thank you.
I'm a registered nurse, and I was one of the founders of Health Care Without Harm in 1996. Health Care Without Harm is an international campaign on environmental responsibility in the health care industry. In that first year, in 1996, it was part of my job to review the science on phthalates to decide whether or not there was enough to include it in the original mission and goals of Health Care Without Harm.
At that time there were a few studies about phthalates as a carcinogen, some about phthalates as a cardiotoxic chemical, but there wasn't enough. I recommended against including phthalates in the first mission and goals of Health Care Without Harm, because compared to dioxin, compared to mercury, there just wasn't a lot of science there. But in just a few years, in three years, there were so many studies that had been done that were so profound in looking at phthalates not as a carcinogen but as a reproductive toxin that we were part of the effort at the national toxicology program in the United States to look at phthalates and have it listed as a reproductive toxin.
Then my history as a nurse in a neonatal intensive unit became useful, because the research docs, the toxicologists who were in the NTP, really hadn't spent much time in NICU and didn't understand the multiple exposures that a child could have from the tube giving nourishment, the tube giving air, the tube giving IV fluids, the isolate itself, the vinyl gloves of a nurse. All of those were different exposures that needed to add up.
At the same time, there were new studies that showed that you really had to think about exposure to different phthalates in a cumulative way so that the phthalates from the shower curtain made out of vinyl and the phthalates from the vinyl dashboard in your car got added to the phthalates in medical devices, got added to the phthalates in cosmetics, and between them could be enough to cause harm, especially to babies in the womb and very young children.
In 2000 NTP found DEHP to be a reproductive toxin, and Health Care Without Harm worked with the FDA to issue a public health notification. We got to spend a lot of time in hospitals that were trying to implement this new public health notification. We realized, and this is what I've come to talk to you today about, that it's not enough to label, and it's not enough to label and educate, because when a baby presents in a neonatal intensive care unit, that's the wrong time for the physician or for the parent to be specifying DEHP-free. You want every device that can be free of DEHP, and there are always going to be some exceptions, to be phthalate-free if possible.
Since the NTP made its findings in 2000, there have been 150 studies on the reproductive toxicity of DEHP and other phthalates. I want to tell you about four of them that came out in the last twelve months. A 2006 study of vinyl flooring factory workers in China showed that these workers had higher levels of DBP and DEHP than a control population, and lower levels of free testosterone. A 2006 study from Finland tied DHP from vinyl wall coverings to adult onset asthma in office workers. A Boston study found that men with more DBP had impaired sperm quality than at levels that you find in the general population. And a German study of rats showed that low levels of DHP suppressed the activity of the key enzyme that's necessary for the masculization of the brain.
The findings of each of these studies is supported by most of the hundred plus other pieces of peer-reviewed research. While there are confounding reports, often funded by industry, the weight of the evidence is that the DHP, BBP, DBP, and other phthalates are toxic to the male reproductive system, that they are anti-androgens, interfering with a male rat or a baby boy's in utero capacity to become male.
Let me just explain how it works. All of us start out as girls in the womb, and then if you have a Y chromosome, the body is lightly bathed in a wash of testosterone, and that's what turns female embryos into male babies. Phthalates seem to interfere with the testosterone bath. What we see is what's called testicular dysgenesis syndrome, TDS, that's linked to testicular cancer, undescended testes, hypospadias, and low sperm counts. I want to suggest to you that those are the parts of being male that we can see, and that we have reason to be concerned about what anti-androgens are also doing to the parts of maleness that we can't see.
Given the cumulative properties of phthalates, and given that phthalates cross the placenta, and given the alarming CDC data on phthalates in women of childbearing age, some of us in Health Care Without Harm worry that what good was it doing us to get phthalates out of medical devices where we could, if women were going to present in labour already full of phthalates?
So we started looking for phthalates on the labels of personal care products, because we knew phthalates were in women at higher levels than in men. When we couldn't find them on the labels, except for nail polish, we did our own testing and found phthalates in 72% of the products we tested.
I brought you one of the products we tested. This is actually from the sample. This is Poison, by Christian Dior--aptly named--which had more phthalates than any other product we tested. I brought it today because while you would think that while it had BBP and DEHP and DP and DBP in 2002, something would have changed in the five years since then. But at the beginning of this year, January 2007, Consumer Reports did their own follow-up testing of phthalates in personal care products. They tested both the European and the U.S. versions of Poison and still found DEHP and DBP in the products.
I want to close by saying why I think that's really important.
Christian Dior doesn't add DEHP on purpose. When they add the fragrance, the DEHP is there. In the same way, the manufacturers of teething rings or rubber duckies aren't adding phthalates on purpose; they're making products out of vinyl, and the phthalates are in the vinyl. So it's very important in the language of these bills that it not just be what's voluntarily added, but actually what's in the product to be able to actually enforce the law in the way you want to. If there is language like that, we're going to be continuing the don't look, don't tell, don't test, and deny-and-spread-doubt culture. That culture dominates current chemical policy in the United States. And I have come all this way from California because I am hopeful that we will be able to change that situation soon in the U.S., both federally and in the states, especially if we have your leadership.
So let me just close by saying that as a nurse, as someone who has followed the phthalate science, as someone who was an early doubter of the danger of phthalates, but mostly as a mother of sons and as someone who is a little bit desperate to become a grandmother, I urge you to pass the strongest possible bill. I am proud to be a woman, but I want my sons and my grandsons to grow up to be the men they were supposed to be, not the products of phthalate contamination.
Thank you.
