BPA hormone disruptor contaminates Earth’s oceans

BPA hormone disruptor contaminates Earth’s oceans

Earlier this year, research linked bisphenol A (BPA), a common component of plastics and a powerful hormone disrupter, to heart disease (http://www.naturalnews.com/027974_b…). Now, in the March issue of the Journal of the Federation of American Societies for Experimental Biology, researchers have reported yet another newly discovered danger posed by BPA. Hugh S. Taylor, M.D., professor in the Department of Obstetrics, Gynecology and Reproductive Sciences at Yale University, and his research team have found for the first time that BPA exposure during pregnancy can cause abnormalities in the uterus of offspring and permanent alterations in DNA.

But at least you can avoid plastics and therefore avoid exposure to the BPA, right? Unfortunately, another group of scientists has just announced that’s getting harder and harder to do. Bottom line: there is now solid evidence that Earth’s oceans have been contaminated on a global scale with BPA.

Katsuhiko Saido, Ph.D., of Nihon University in Chiba, Japan, and his colleagues announced their startling and worrisome findings at the 239th National Meeting of the American Chemical Society held in San Francisco recently. He stated that the massive BPA contamination of oceans resulted from hard plastic trash thrown in the seas as well as from another surprising source — the epoxy plastic paints used to seal the hulls of ships.

“This new finding clearly demonstrates the instability of epoxy, and shows that BPA emissions from epoxy do reach the ocean. Recent studies have shown that mollusks, crustaceans and amphibians could be affected by BPA, even in low concentrations,” Dr. Saido said in a statement to the media.

The scientists noted that light, white-foamed plastic decomposed rapidly at temperatures commonly found in the oceans, releasing the endocrine disruptor BPA. It isn’t just soft plastics that leach BPA, either.

“We were quite surprised to find that polycarbonate plastic biodegrades in the environment,” Dr. Saido explained. “Polycarbonates are very hard plastics, so hard they are used to make screwdriver handles, shatter-proof eyeglass lenses, and other very durable products. This finding challenges the wide public belief that hard plastics remain unchanged in the environment for decades or centuries. Biodegradation, of course, releases BPA to the environment.”

Dr. Saido’s research team analyzed sand and seawater from over 200 sites in 20 countries, including areas in Southeast Asia and North America. Every site tested contained what Dr. Saido labeled as “significant” amounts of BPA, ranging from 0.01 parts per million (ppm) to 50 ppm.

Dr. Saido pointed out that littering currently results in about 150,000 tons of plastic debris washing up on the shores of Japan alone each year. In addition, a huge area of plastic waste known as the Great Pacific Garbage Patch, which is about two times the size of Texas, now contaminates the area between California and Hawaii. “Marine debris plastic in the ocean will certainly constitute a new global ocean contamination for long into the future,” Dr. Saido predicted in the press statement.

In yet more BPA news, Rolf Halden, associate professor in the School of Sustainable Engineering at Arizona State University and assistant director of Environmental Biotechnology at the Biodesign Institute, has just published a sobering research article on the hazards of chemical-loaded plastics. His findings, which are included in the latest issue of the Annual Review of Public Health, provide more evidence that plastics in garbage dumps, landfills and the world’s oceans are an ever-increasing toxic problem.

In fact, Dr. Halden concluded in his paper that plastics and their additives such as BPA aren’t only around us; they are inside virtually every human. The chemicals show up in blood and urine tests because they are ingested with the food we eat, the water we drink and from other environmental exposures.

“We’re doomed to live with yesterday’s plastic pollution and we are exacerbating the situation with each day of unchanged behavior,” Dr. Harden said in a press statement. “We are at a critical juncture and cannot continue under the modus that has been established. If we’re smart, we’ll look for replacement materials, so that we don’t have this mismatch — good for a minute and contaminating for 10,000 years.”

New study confirms bisphenol A found in plastic is linked to heart disease

According to the American Heart Association, cardiovascular disease is the number one killer in the U.S. Various forms of the disease take the lives of over 80 million Americans a year. And while we’ve all heard about the risk factors for cardiovascular disease — including smoking, being overweight, high cholesterol and lack of exercise — it appears it’s time to add bisphenol A, better known as BPA, to that list.

This chemical has been used for decades in polycarbonate plastic products including refillable drink containers, plastic eating utensils and baby bottles as well as the epoxy resins that line most food and soft-drink cans. Now a new study just published in the journal PLoS ONE provides the most compelling evidence so far that BPA exposure is dangerous to the cardiovascular system.

Using 2006 data from the US government’s National Health and Nutrition Examination Survey (NHANES), researchers from the Peninsula Medical School at the University of Exeter in the UK studied urinary BPA concentrations and found a significantly strong link between BPA exposure and heart disease. In 2008, these same scientists discovered that higher urinary BPA concentrations were associated with a long list of medical problems in adults, including liver dysfunction, diabetes and obesity. This research team was also the first to report evidence that BPA was linked to cardiovascular disease — and their new research offers further confirmation of a strong connection between BPA and heart ailments.

Despite the fact the new study found that urinary BPA concentrations were one third lower than those measured from 2003 to 2004, higher concentrations of BPA were still associated with heart disease. “This is only the second analysis of BPA in a large human population sample. It has allowed us to largely confirm our original analysis and exclude the possibility that our original findings were a statistical ‘blip’,” David Melzer, Professor of Epidemiology and Public Health at the Peninsula Medical School and the research team leader, said in a statement to the media.

“We now need to investigate what causes these health risk associations in more detail and to clarify whether they are caused by BPA itself or by some other factor linked to BPA exposure. The risks associated with exposure to BPA may be small, but they are relevant to very large numbers of people. This information is important since it provides a great opportunity for intervention to reduce the risks,” added scientist Tamara Galloway, Professor of Ecotoxicology at the University of Exeter and senior author of the paper.

As NaturalNews has previously reported, BPA exposure has been shown in other studies to be associated with neurological problems (http://www.naturalnews.com/025801_B…), diabetes and aggressive behavior in little girls (http://www.naturalnews.com/027382_B…). Unfortunately, the FDA has demonstrated little ability or interest in taking decisive measures to protect consumers from this chemical (http://www.naturalnews.com/024593_t…).Your best strategy to avoid BPA? Eat natural, fresh foods and stay away from cans, bottles and other plastic containing products that are not certified BPA-free.

Six Risky Chemicals You’re Carrying in Your Body

The U.S. Centers for Disease Control and Prevention has released its latest assessment of the chemicals people are carrying around in their bodies.

The biomonitoring study is the most comprehensive in the world, measuring 212 chemicals in the blood and urine of 8,000 Americans.

The CDC highlighted a few chemicals because they are both widespread — found in all or most people tested — and potentially harmful.

Here’s a look at what they are and how you can try to avoid them:

Polybrominated diphenyl ethers

    Better known as “flame retardants”, PBDEs are used widely in all sorts of goods to reduce fire risk. They also accumulate in human fat, and some studies suggest they may harm your liver and kidneys as well as your neurological system. Some states have restricted the use of certain PBDEs, but short of such bans, avoiding them is difficult because the chemicals are integrated into so many products.

Bisphenol A

    BPA, which is found in many plastics, in the lining of cans, and even coating many sales receipts, was found in more than 90 percent of Americans tested. The health concerns about BPA are many and growing. While BPA-free products are available, it can be difficult to find them unless you do research ahead of time.

PFOA

    PFOA and other perfluorinated chemicals are used to create heat-resistant and non-stick coatings on cookware, as well as grease-resistant food packaging and stain-resistant clothing. Studies have linked these chemicals to a range of health problems, including infertility in women, and to developmental and reproductive problems in lab animals. Avoiding products that contain them is a first step towards avoiding them.

Acrylamide

    Formed when carbohydrates are cooked at high temperatures (fried foods), acrylamide and its metabolites are extremely common in Americans. High-level exposure has caused cancer and neurological problems in lab animals and workers, respectively. Avoiding it in food comes down to food choice, storage and preparation.

Mercury

    The main source of mercury — a potent neurotoxin that can lead to permanent brain damage if young children or fetuses are exposed — continues to be contaminated fish. I do not recommend eating most fish for this reason (mercury is also found in amalgam tooth fillings and vaccines).

MTBE

    This gasoline additive has been phased out of use in the U.S. in favor of ethanol, but it still can be detected widely in American’s bodies; it has contaminated many drinking water supplies. Studies have linked it to a variety of potential problems, including neurological and reproductive damage.

A study released Wednesday which found that nine of 10 babies tested were born with bisphenol A in their systems has renewed calls for the chemical to be banned.

In the study commissioned by the Environmental Working Group, scientists found the chemical in nine of 10 randomly selected samples of umbilical cord blood.

Previous studies have found BPA in the urine of 93% of Americans tested. But Wednesday’s study is the first to find it in the cord blood of U.S. newborns.

“It’s alarming,” Janet Gray, director of the Environmental Risks and Breast Cancer project at Vassar College, said of the study results. “What more evidence do we need to act?”

BPA Side Effects Include: Breast cancer, prostate cancer, diabetes, obesity, ADHD, miscarriage, sterilization, erectile dysfunction, impotence, increased estrogen, feminized newborn boys, down’s syndrome, transgender newborns, early onset puberty, memory loss, increased aggression.

Phthalate warning: Medications contain chemicals that “feminize” unborn baby boys

Natural News
November 17, 2009

In a bombshell finding that has far-reaching implications for society and culture, scientists at the University of Rochester have found that phthalates — the chemical found in many vinyl and plastic products — tends to “feminize” boys, altering their brains to express more feminine characteristics. The study has been published in the Journal of Andrology.

Phthalates are found in vinyl products (including vinyl flooring), PVC shower curtains, plastic furniture and even in the plastic coating of the insides of dishwashing machines.

The feminization process happens during pregnancy when phthalate exposure causes hormone disruptions in the unborn baby. This chemical feminizes males by disrupting the action of the hormone testosterone.

In this recent study, researchers found a strong correlation between the types of toys that male children play with and the level of phthalates found in their mothers when they were pregnant. Researchers discovered that boys exposed to high levels of phthalates in the womb tend to avoid playing with cars, trains or toy guns. They also avoided rough play, instead preferring more feminine toys and activities. (Barbie?)

Phthalates used in pharmaceutical coatings

What very few people know about phthalates is that they are used in the coatings of pharmaceuticals to create “enteric” coatings. This means that many people taking certain pharmaceuticals are unknowingly eating phthalates. If expectant mothers take such pharmaceuticals during pregnancy, they may then feminize their unborn male babies.

How do we know phthalates are used in pharmaceuticals? This Google Books link (http://books.google.com/books?id=e7…) shows a page from the Handbook of Pharmaceutical Manufacturing Formulations: Over-the-counter products. In it, a recipe is given for manufacturing a clear enteric coating. The ingredients are:

Acetone
Purified water
Hydroxypropyl Methyl Cellulose Phthalate
Vanillin
Acetylated Monoglycerides
Alcohol

This combination of highly toxic chemicals is cooked, stirred and then used to coat pharmaceutical pills that people actually swallow!

Here’s a patent that describes the process in more detail:

Phthalates in antidepressant SSRI drugs
These phthalate chemicals are also used in antidepressant drugs. Here’s a patent that describes the process: “Controlled Release Compositions of an Antidepressant Agent” http://www.faqs.org/patents/app/200…

As the patent explains:

“…the enteric coating polymer is selected from the group consisting of cellulose acetate phthalate, polyvinyl acetate phthalate, methacrylicacid copolymer, cellulose acetate trimellitate, shellac, hydroxypropyl methylcellulose phthalate, hydroxypropyl methylcellulose acetate succinate and combination thereof.”
