Chemical in Plastics May Alter Boys' Genitals Before Birth
Baby boys who are exposed in the womb to a chemical used in soft plastics may show small signs of altered genital development, according to new research published today.
The study, which included more than 700 infants in four U.S. cities, is the largest of its kind to date. It confirms earlier findings in humans and animals that exposure to certain types of chemicals called phthalates may lead to changes in the way the male reproductive tract develops, said Dr. Russ Hauser, an epidemiologist at the Harvard School of Public Health, who was not involved in the new study.
Phthalates are a large group of industrial chemicals used in a variety of consumer products, such as food packaging, flooring, perfumes and lotions. ...

Chemicals in plastic 'are making women less interested in sex': Low libido linked to additives used to soften materials found in every home
Chemicals found in PVC flooring, plastic shower curtains, processed food and other trappings of modern life may be sapping women's interest in sex.
A study has linked low libido with the additives used to soften plastics which are found in every home.
Women with the highest levels of phthalates in their bodies were more than twice as likely to say 'not tonight dear' as those with the lowest amounts.

'Chemicals of Concern' list still wrapped in OMB red tape
For anyone anxious about toxic chemicals in the environment, Sunday marked a dubious milestone.
It has been three years since the "chemicals of concern” list landed at the White House Office of Management and Budget. The list, which the Environmental Protection Agency wants to put out for public comment, includes bisphenol A, a chemical used in polycarbonate plastic water bottles and other products; eight phthalates, which are used in flexible plastics; and certain flame-retardant compounds called polybrominated diphenyl ethers, or PBDEs....The EPA proposal arrived at OIRA on May 12, 2010. There it remains -- a symbol, some say, of a broken regulatory system. ...

Plastics chemicals linked to diabetes in women; blacks and Hispanics most exposed
A group of chemicals found in household plastics and medical supplies is linked to higher rates of diabetes in women -- up to double the rate for women with the highest levels, according to new research led by Harvard scientists. Blacks and Mexican Americans and women living in poverty are exposed to the highest levels of some of these compounds, called phthalates. "It's extremely likely that phthalates and other chemical contaminants will turn out to be a big part of the obesity and diabetes epidemic, but at this point we really don't know how these chemicals are interacting with each other, or with the human body," said Richard Stahlhut, a university of Rochester scientist who co-authored the study. ...

What Do We Know about Obesogens? with Bruce Blumberg
Human beings, as a species, are putting on weight. Obesity rates are rising in rich and poor countries alike for a variety of reasons, from changing dietary habits and activity levels to exposure to artificial nighttime light. Mounting evidence from over the past decade suggests that certain chemicals may be playing a role as well. For some people, so-called obesogens may be altering their metabolism and fat cell development, making it harder to maintain a healthy weight. ...

Effects of Environmental Toxicants Reach Down Through Generations
A Washington State University researcher has demonstrated that a variety of environmental toxicants can have negative effects on not just an exposed animal but the next three generations of its offspring.
The animal's DNA sequence remains unchanged, but the compounds change the way genes turn on and off -- the epigenetic effect studied at length by WSU molecular biologist Michael Skinner and expanded on in the current issue of the online journal PLoS ONE....
"We didn't expect them all to have transgenerational effects, but all of them did," Skinner told the technology website Gizmodo....
Researchers tested a pesticide mixture (permethrin and insect repellant DEET), a plastic mixture (bisphenol A and phthalates), dioxin (TCDD) and a hydrocarbon mixture (jet fuel, JP8)....
The researchers saw females reaching puberty earlier, increased rates in the decay and death of sperm cells and lower numbers of ovarian follicles that later become eggs.

Infertile couples have higher exposure to phthalates
Infertile couples are exposed to three to five times higher levels of phthalates compared to fertile couples who have naturally conceived a child, finds a study from Italy. The couples had higher levels of four different classes of phthalates in their urine, including the phthalate compound most commonly used in plastics and the compound most commonly used in cosmetics.
Phthalates can act as endocrine disrupting chemicals, mimicking or interfering with the actions of natural hormones like estrogen. Prior research shows phthalates can cause problems such as pregnancy loss and reduced litter size in rodents, though animals in these studies were exposed to levels about 100 times greater than the general population. ...

Childhood obesity linked to phthalate exposure.
Overweight children tend to have higher levels of certain phthalate metabolites in their urine, according to a year-long study of minority populations in New York City.
The trend was not seen in normal weight children. The researchers found the relationship only with one kind of phthalate known as MEP. More specifically, they report that a 10-fold increase in MEP concentrations was associated with subsequent increases in body mass index (BMI) and waist size.
This is the first study to examine the association between phthalate exposure and body weight measures in children. Prior studies in teens and women find a similar association between the same phthalate -- MEP -- and the same two body measures. ...

Researchers find school packed lunches contaminated with phthalates
Scientists have found that food packaging appears to increase the levels of two phthalates in lunches fed to children by up to 50 percent, following a study in Italy.
Researchers from the University of Naples measured the levels of di(2-ethylhexyl)phthalate (DEHP) and di-n-butylphthalate (DBP) in packed school meals prepared for children aged between 3 and 10 years old, and estimated the influence of the packaging process on meal contamination and the contribution to daily intake.
They found that 92 percent of foodstuffs employed in meal preparation contained DEHP, and 76 percent of them DBP, at detectable levels. By comparing food contents before and after packaging, the researchers found that the packaging process contributed to a significant increase in the level of the two chemicals, estimating that for young children school meals can increase daily DEHP intake by up to 18 percent and DBP by up to 50 percent. ...

Chemicals Of Concern
The White House is under pressure from two democratic senators to release a list of chemicals the Environmental Protection Agency says could endanger human health or the environment. This so-called chemicals of concern list would include eight phthalates, polybrominated diphenyl ethers, and bisphenol A.
The chemical industry has attempted to block release of EPA's proposed list over the past year.
Congress granted EPA the authority to create such a list in the Toxic Substances Control Act (TSCA), which was signed into law in 1976. But EPA hasn't attempted to use this authority until now. ...

Common plasticizer alters an important memory system in male rat brains.
An ingredient widely-used to soften plastic containers and toys changed brain development in growing male rats when exposure occurs during a sensitive phase. The same exposure did not affect female rats, report researchers in the journal Neuroscience.
The animal study shows that the phthalate DEHP can disrupt the normal development of the hippocampus in young male rats by reducing the number of cells and nerve connections that form. The hippocampus is important to learning as it is involved in the formation of long-term memories. The rat hippocampus matures in the first few weeks after birth while in people, the hippocampus largely develops before birth during the third trimester.
This is the first research to connect phthalate exposure at a critical time of development with these cell and nerve effects in the hippocampus. ...

'Gender-Bending' Chemicals Found in Toys in China
Toy manufacturers are exposing children in China to high levels of industrial chemicals known as phthalates that the U.S. and European Union have banned from children's products, the environmental organization Greenpeace says.
Phthalates, the best-known of which is DEHP, are used to soften plastic children's toys. The U.S. Centers for Disease Control and Prevention has classified them as probable human carcinogens. They have also been linked to "gender-bending." A 2005 study, for instance, suggested that phthalates could affect the genital development of boys, and other research has associated the chemicals with the early onset of puberty in girls.
Congress passed a ban in 2008 after concluding that the chemicals posed a risk to children who chew on their toys.
But there is no such ban in China and, according to Greenpeace, testing by an independent laboratory found phthalates in 21 out of 30 samples of children's products purchased in four Chinese cities. ...

Better by Design
...Many of today's chemicals -- in packaging, cleaning products, furniture and elsewhere -- go where they should not go and do more than they were designed to do. Bisphenol A, a common ingredient in polycarbonate plastics, has made headlines for getting into the body and interfering with tissue development and function (SN: 7/18/09, p. 5). Flame retardants new and old persist in the environment, contaminating soil, waterways and wildlife (SN: 4/24/10, p. 12). And a new analysis, reported online January 14 in Environmental Health Perspectives, finds that the blood and urine of 99 percent of pregnant American women tested contain a laundry list of chemical interlopers, including various PCBs, pesticides, PFCs, PBDEs, phthalates and the rocket-fuel ingredient perchlorate.
Unless there is a fundamental shift in the way that chemicals are created from the outset, the next generation of compounds will probably be just as meddlesome... Currently more than 30 million metric tons of chemicals are produced in or imported to the United States each day, a quantity that would fill a line of tanker trucks 10,000 miles long. And industrial chemical production is expected to double in the next quarter century, outpacing population growth. ...

Toxics found in virtually all pregnant U.S. women tested in UCSF study
Multiple chemicals, including some banned since the 1970s and others used in items such as nonstick cookware, furniture, processed foods and beauty products, were found in the blood and urine of pregnant U.S. women, according to a UCSF study being released today.... Of the 163 chemicals studied, 43 of them were found in virtually all 268 pregnant women in the study. They included polychlorinated biphenyls or PCBs, a prohibited chemical linked to cancer and other health problems; organochlorine pesticides; polybrominated diphenyl ethers, banned compounds used as flame retardants; and phthalates, which are shown to cause hormone disruption.
Some of these chemicals were banned before many of the women were even born.... The chemicals found in 99 percent to 100 percent of the women included certain PCBs, organochlorine pesticides, perfluorinated compounds, phenols, PBDEs, phthalates, polycyclic aromatic hydrocarbons and perchlorate.

David Suzuki targets 'dirty dozen' toxic ingredients
The David Suzuki Foundation took aim Tuesday at a "dirty dozen" chemicals that are found in 80 per cent of the most common cosmetic products and urged better labelling laws to help consumers avoid them.
In a report on a chemical survey, the foundation said it got 6,200 volunteers to check the ingredients listed on 12,550 everyday cosmetic products, including shampoo, toothpaste, lipstick and skin cleanser.
When the results came in, four out of five products on the list of 12, 550 were found to contain at least one of the 12 chemicals, said Lisa Gue, the group's health policy analyst....
1 - BHA and BHT. Used in moisturizers as preservatives, the suspected endocrine disruptors may cause cancer and are known to be harmful to fish and other wildlife
2 - Coal-tar dyes such as p-phenylenediamine and colours listed as CI followed by five digits. Used in some hair dyes, may be contaminated with heavy metals toxic to the brain.
3 - DEA, cocamide DEA and lauramide DEA. Used in some creamy and foaming moisturizers and shampoos. Can react to form nitrosamines, which may cause cancer. Harmful to fish and other wildlife.
4 - Dibuytl phthalate. Used as a plasticizer in some nail-care products. Suspected endocrine disrupter and reproductive toxicant. Harmful to fish and other wildlife.
5 - Formaldehyde releasing preservatives such as DMDM hydantoin, diazolidinyl urea, imidazolidinyl urea, methenamine, quarternium-15 and sodium hydroxymethylglycinate. Used in a variety of cosmetics. Slowly release small amounts of formaldehyde, which causes cancer....

Homes of the Poor and the Affluent Both Have High Levels of Endocrine Disruptors
Homes in low-income and affluent communities in California both had similarly high levels of endocrine disruptors, and the levels were higher in indoor air than outdoor air, according to a new study believed to be the first that paired indoor and outdoor air samples for such wide range (104) of these substances. The study appears in ACS' Environmental Science & Technology.... Examples include phthalates, which are found in vinyl and other plastics, and polychlorinated biphenyls (PCBs), which are found in older paints, electrical equipment, and building materials. EDCs also are among the ingredients in some pesticides, fragrances, and other materials.... Levels were generally higher indoors than outdoors -- 32 of the compounds occurred in higher concentrations indoors and only 2 were higher outdoors. The scientists expressed surprise at finding higher concentrations of some phthalates outdoors near urban homes contributing to higher indoor levels as well, but concluded that EDCs "are ubiquitously common across socioeconomic groups." ...

Exposure to 3 classes of common chemicals may affect female development
Researchers at Mount Sinai School of Medicine have found that exposure to three common chemical classes--phenols, phthalates and phytoestrogens--in young girls may disrupt the timing of pubertal development, and put girls at risk for health complications later in life. The study, the first to examine the effects of these chemicals on pubertal development, is currently published online in the journal Environmental Health Perspectives.
"Research has shown that early pubertal development in girls can have adverse social and medical effects, including cancer and diabetes later in life," said Dr. Mary Wolff, Professor of Preventive Medicine and Oncological Sciences at Mount Sinai School of Medicine. "Our research shows a connection between chemicals that girls are exposed to on a daily basis and either delayed or early development. While more research is needed, these data are an important first step in continuing to evaluate the impact of these common environmental agents in putting girls at risk."... Phenols, phthalates and phytoestrogens are among chemicals known as endocrine disruptors, which interfere with the body's endocrine, or hormone, system. They are found in a wide range of consumer products, such as nail polishes, where they increase durability, and in cosmetics, perfumes, lotions, and shampoos, where they carry fragrance. Some are used to increase the flexibility and durability of plastics such as PVC, or are included as coatings on medications or nutritional supplements to make them timed-release. ...

Perils of plastics: Risks to human health and the environment
Halden's study reiterates the fact that the effects to the environment from plastic waste are acute. Measurements from the most contaminated regions of the world's oceans show that the mass of plastics exceeds that of plankton sixfold. Patches of oceanic garbage--some as large as the state of Texas--hold a high volume of non-biodegradable plastics.... "We're doomed to live with yesterday's plastic pollution and we are exacerbating the situation with each day of unchanged behavior," he said.... BPA has been recognized since the 1940s as an endocrine disrupting chemical that interferes with normal hormonal function.
Adding to the health risks associated with BPA is the fact that other ingredients--such as plasticizers [like pthalates]--are commonly added to plastics.... "Today, there's a complete mismatch between the useful lifespan of the products we consume and their persistence in the environment." Prominent examples of offending products are the ubiquitous throwaway water bottles, Teflon-coated dental floss and cotton swabs made with plastic PVC sticks. All are typically used for a matter of seconds or minutes, yet are essentially non-biodegradable and will persist in the environment, sometimes for millennia. ...

Saving face
We turn to cosmetics to look our very best, but sometimes all that lathering, slathering, powdering and painting can do more harm than good. * Certain ingredients in personal care products can cause redness, itching, swelling, acne and other reactions in people who are sensitive to them.

IBM, Stanford cite advance in plastic recycling
When you recycle a plastic bottle, it doesn't necessarily become another plastic bottle. Because of limitations in recycling technology, a common type of plastic used in water bottles and food containers weakens so much when it's recycled that it can't be used again for the same purpose. Some small amount of the plastic might make it into another bottle, but more often than not, it instead becomes synthetic carpet or clothing and can't easily be recycled a second time. So when those products are used up, they end up in landfills.
Researchers from IBM Corp. and Stanford University believe they have developed a way to significantly improve the quality of recycled plastic and strip away those limitations.... The innovation is a new family of catalysts that can reduce polyethylene terephthalate (PET) plastic to its basic building blocks, while retaining its original properties and making it "ridiculously economical" to build it back up again, said Bob Allen, senior manager of chemistry and functional materials for IBM's Almaden research center in Silicon Valley. ...

Study finds prenatal exposure to certain chemicals affects childhood neurodevelopment
A new study led by Mount Sinai researchers in collaboration with scientists from Cornell University and the U.S. Centers for Disease Control and Prevention, has found higher prenatal exposure to phthalates -- manmade chemicals that interfere with hormonal messaging -- to be connected with disruptive and problem behaviors in children between the ages of 4 and 9 years. The study, which is the first to examine the effects of prenatal phthalate exposure on child neurobehavioral development, will be published January 28, on the Environmental Health Perspectives website.... "There is increasing evidence that phthalate exposure is harmful to children at all stages of development," said Stephanie Engel, PhD, lead study author and Associate Professor of Preventive Medicine at Mount Sinai School of Medicine. "We found a striking pattern of associations between low molecular weight phthalates -- which are commonly found in personal care products -- and disruptive childhood behaviors, such as aggressiveness and other conduct issues, and problems with attention. These same behavioral problems are commonly found in children diagnosed with Attention-Deficit Hyperactivity Disorder (ADHD), Oppositional Defiant Disorder, or Conduct Disorder." ...

What the EPA's 'Chemicals of Concern' Plans Really Mean
In an unusual exercise of its authority under the Toxic Substances Control Act (TSCA), the U.S. Environmental Protection Agency announced on December 30 the establishment of a "chemicals of concern" list and action plans that could prompt restrictions on four types of synthetic chemicals used widely in manufacturing and consumer products, including phthalates used to make flexible plastics, often for toys, household products and medical equipment.... Of the compounds covered in the action plans -- which also include polybrominated diphenyl ethers (PBDEs), long-chain perfluorinated chemicals (PFCs) and short-chain chlorinated paraffins (SCCPs) -- phthalates and PBDEs will be listed as "chemicals of concern." The PFCs and paraffins will be addressed under other TSCA provisions that could also result in restrictions.
These four types of chemicals, the EPA said, raise "serious environmental or health concerns" and in some cases "may present an unreasonable risk of injury to health and the environment." ...

NY scientists to study affect of everyday toxins
New York scientists have been awarded a $5 million federal grant to study long-term human exposure to chemicals in the environment.
Chemicals can pop up in plastic bottles, toys, medical equipment and pillows and upholstery. Scientists are looking to see if micro-amounts of environmental compounds that humans are exposed to will stay in the body, or have lasting effects. California and Washington state also have been awarded grants.
Scientists will take samples of urine, blood and saliva, and even test the breath of subjects... They'll measure how much and what kinds of chemicals are flowing through blood and fat tissue. Some of those chemicals are metabolized and leave the body, while others hang around. ...

Chemicals in plastics alter the brains of baby boys, making them "more feminine", say US researchers.
Males exposed to high doses in the womb went on to be less likely to play with boys' toys like cars or to join in rough and tumble games, they found....Phthalates have the ability to disrupt hormones, and have been banned in toys in the EU for some years.
However, they are still widely used in many different household items, including plastic furniture and packaging.
There are many different types and some mimic the female hormone oestrogen. ...

Pilot study relates phthalate exposure to less-masculine play by boys
A study of 145 preschool children reports, for the first time, that when the concentrations of two common phthalates in mothers' prenatal urine are elevated their sons are less likely to play with male-typical toys and games, such as trucks and play fighting.... Because testosterone produces the masculine brain, researchers are concerned that fetal exposure to anti-androgens such as phthalates -- which are pervasive in the environment -- has the potential to alter masculine brain development... Phthalates are also found in vinyl and plastic tubing, household products, and many personal care products such as soaps and lotions. Phthalates are becoming more controversial as scientific research increasingly associates them with genital defects, metabolic abnormalities, and reduced testosterone in babies and adults. ...

Two-year-olds at risk from 'gender-bending' chemicals, report says
Two-year-old children are being exposed to dangerous levels of hormone-disrupting chemicals in domestic products such as rubber clogs and sun creams, according to an EU investigation being studied by the government.
The 327-page report says that while risks from "anti-androgen" and "oestrogen-like" substances in individual items have been recognised, the cumulative impact of such chemicals, particularly on boys, is being ignored....Phthalates, one of the main anti-androgen chemicals, which are used as softeners in soap, rubber shoes, bath mats and soft toys, have been blamed for blocking the action of testosterone in the womb and are alleged to cause low sperm counts, high rates of testicular cancer and malformations of the sexual organs. ...

Phthalates may play a role in pre-term births
A new study of expectant mothers suggests that a group of common environmental contaminants called phthalates, which are present in many industrial and consumer products including everyday personal care items, may contribute to the country's alarming rise in premature births.
Researchers at the University of Michigan School of Public Health found that women who deliver prematurely have, on average, up to three times the phthalate level in their urine compared to women who carry to term.... Phthalates are commonly used compounds in plastics, personal care products, home furnishings (vinyl flooring, carpeting, paints, etc.) and many other consumer and industrial products. The toxicity varies by specific phthalates or their breakdown products, but past studies show that several phthalates cause reproductive and developmental toxicity in animals. ...

Birth defect of the male urethra is not increasing in New York state
In recent decades, there have been periodic reports of a worldwide decline in sperm count and quality. Male infertility has ostensibly been on the rise, accompanied by increases in testicular cancer and hypospadias -- a congenital defect in which the opening of the urethra is on the underside, rather than at the end, of the penis. Taken together, these three conditions have been termed testicular dysgenesis syndrome.
Environmental chemicals known as phthalates, some researchers say, may be the cause of the problem. Used in the manufacture of plastics, phthalates at sufficiently high levels have been seen to interfere with male fetal development. Some studies have found that hypospadias are more prevalent among male infants today than they were 30 years ago.
Now, a team of researchers ... have taken a fresh look at the data and have found no rise in rates of hypospadias in New York State from 1992 to 2005. Similar findings have been reported by researchers looking at state-level data in Washington and California.... When combined with recent research showing that sperm counts are not declining, the current study suggests that testicular dysgenesis syndrome may not be a problem in humans, contrary to earlier concerns. ...

Chemical pollution gets personal
In their book Slow death by rubber duck, the pair detail a weekend testing spree incorporating regular blood and urine sampling. Indoors for 12-hour shifts, they used typical amounts of personal care products and a plug-in air freshener, in a room with stain-repellent furnishings and carpets. 'We set only one ironclad rule: our efforts had to mimic real life,' says Smith. Of six different phthalates in the testing regime, rocketing levels of monoethyl phthalate (MEP) -- which the body metabolises from diethyl phthalate (DEP) the most common phthalate in cosmetics and personal care products -- were most stark. Levels in urine went from 64 to 1410ng/ml. According to the European Commission's Scientific Committee for Cosmetic Products (SCCP), traces of up to 100 ppm total or per substance pose no risk to health, although traces of banned phthalates are sometimes present due to other possible uses, such as in packaging. Phthalates are plasticising chemicals, linked to abnormal reproductive development.... Levels of bisphenol A -- an endocrine disruptor linked to breast and prostate cancer -- increased 7.5 times after eating canned foods from a microwavable, polycarbonate plastic container. ...

Plastic Water Bottles May Pose Health Hazard
With all of the bad press swirling around certain types of plastic lately, regular old plastic water bottles have maintained a reputation as safe, at least as far as human health is concerned. New evidence, however, suggests that plastic water bottles may not be so benign after all.
Scientists in Germany have found that PET plastics -- the kind used to make water bottles, among many other common products -- may also harbor hormone-disrupting chemicals that leach into the water. ... "What we found was really surprising to us," [lead researcher Martin] Wagner said. "If you drink water from plastic bottles, you have a high probability of drinking estrogenic compounds." ...

EPA Should Pursue Cumulative Risk Assessment of Phthalates
The U.S. Environmental Protection Agency should examine whether combined exposures to chemicals known as phthalates could cause adverse health effects in humans, says a new report from the National Research Council. In addition, this analysis, called a cumulative risk assessment, should consider other chemicals that could potentially cause the same health effects as phthalates, instead of focusing on chemicals that are similar in structure, which is EPA's current practice. Furthermore, EPA should consider using the recommended approach for future cumulative risk assessments on other kinds of chemicals.... Currently when conducting cumulative risk assessments, EPA often considers only chemicals that are structurally related, on the assumption that they have the same chain of reactions that lead to a final health outcome. That practice ignores how exposures to different chemicals may result in the same health effects. The conceptual approach taken for phthalates -- to consider chemicals that cause similar health effects -- should also be applied when completing any cumulative risk assessment, the committee said. For instance, EPA could evaluate the risk of combined exposures to lead, methylmercury, and polychlorinated biphenyls because all contribute to cognitive deficits consistent with IQ reduction in children. ...
