Chemicals in commerce include pharmaceuticals, pesticides and a large number of industrial chemicals used in consumer products and for other purposes. Each of these large categories of chemicals is regulated by a governmental agency under the authority granted by specific pieces of legislation. Most nonpesticidal industrial chemicals are regulated by the US EPA under the authority as outlined in the 1976 Toxic Substances Control Act (TSCA). Unfortunately, as interpreted and implemented, TSCA has not been adequate to protect public health and the environment, especially for chemicals that have long been in use and that were grandfathered in when TSCA was adopted. The good news is that state and local governments are stepping up to the challenge presented by a system that is not effectively protecting our children's health and development. Several state-based coalitions composed of health, environmental, business and labor leaders are moving forward with practical policy solutions. These solutions are focused around reducing threats, promoting safer alternatives and creating new economic development opportunities. There are also personal and clinical resources to help individuals make informed decisions in their own lives. Speakers will be Ted Schettler MD, MPH, and Sarah Doll.

On this call we will discuss the recent scientific reviews of emerging research on environmental links to breast cancer, published in Cancer, a journal of the American Cancer Society. The reviews cover human studies related to environmental pollutants and other factors such as diet and physical activity. The project also compiled information about chemicals shown to cause mammary gland tumors in animal studies. The three review articles and two commentaries are supported by two publicly accessible online databases that include bibliographic information, key methods and findings, and critical assessments of the strength of the evidence. The databases contain reviews of approximately 450 articles reporting on human breast cancer studies and information on 216 chemicals identified as mammary carcinogens in animal studies. The databases and individual articles are available at http://sciencereview.silentspring.org/index.cfm. This work was conducted by Silent Spring Institute with researchers from Harvard University, Roswell Park Cancer Institute and the University of Southern California. It was supported by Susan G. Komen for the Cure. Joining us to discuss the published articles and the databases will be two of authors of the reviews -- Julia Brody, PhD, executive director of the Silent Spring Institute; and Ruthann Rudel, MS, senior scientist at Silent Spring. Michael Lerner, president of Commonweal and co-founding CHE Partner, will be moderating this hour-long call.

A high-stakes legal battle over a century of smelter contamination dumped into the Columbia River by a Canadian mining and smelting giant may be decided by the U.S. Supreme Court. The court issued an order Monday inviting U.S. Solicitor General Paul Clement -- the lead lawyer for the Bush administration -- to file an amicus brief on behalf of one or more of the parties in the complex case.
Article Summary: Teck Cominco's large lead and zinc smelter is 10 miles north of the border in Trail, BC. The smelter has contaminated the Columbia with heavy metals and black smelter slag, which covers some beaches near Northport. The U.S. Environmental Protection Agency considers the smelter a major source of historic river pollution. Teck Cominco stopped discharging slag to the river in 1994 after a series of Canadian studies showed it was toxic to fish and aquatic life and British Columbia regulators ordered a halt to the dumping. This week's Supreme Court order doesn't necessarily mean the justices have agreed to accept the case, said Mary Sue Wilson, a senior Washington state assistant attorney general in Olympia. Washington state is opposing Supreme Court review because a lower court has already ruled the company is responsible for the cleanup under strict U.S. Superfund laws. The litigation against Teck Cominco was brought by Colville tribal members Joe Pakootas and D.R. Michel under the "citizen suit" provisions of federal Superfund law. The suit was an effort to force the company to pay for a major environmental cleanup of Lake Roosevelt, the 150-mile impoundment of the Columbia behind Grand Coulee Dam. Lawyers for Vancouver, B.C.-based Teck Cominco claim in court documents that the company is not subject to Superfund, the U.S. law governing toxic waste cleanups, because it is based in another country and never "arranged" for the waste to end up in the United States.

Article Summary: A new European study has found that infants who were regularly exposed to the chlorinated air of indoor swimming pools were more at risk for developing asthma than were infants who didn't swim indoors. The researchers found that children who went swimming indoors as infants were 50 percent more likely to report wheezing, almost four times as likely to experience chest tightness, and had more than double the risk of experiencing shortness of breath, compared to the children who hadn't been regular swimmers as infants. The study also found that exposure to passive smoke alone didn't seem to increase a child's risk of asthma, but when coupled with indoor swimming, the risk of developing lung problems was even higher. The study authors suggest that the risk might be higher because exposure to chemicals, such as chlorine, may alter the lining of the lungs, predisposing youngsters to airway disease. Alfred Bernard, the research director of the National Fund for Scientific Research in Belgium, said that parents and pool managers should be aware that chlorine-based disinfectants can be used safely only if their levels are maintained in an optimal range which allows the chlorine to minimize infections without increasing the risk of toxicity. He added, "Another cautious attitude for babies is not to leave them too much time in the water." He also recommended that kids should swim no more than 20 minutes and that parents should discourage infants and young children from drinking pool water.

Here's one more reason not to smoke -- smoking may damage sperm, passing along genetic damage to a man's children, Canadian researchers report. A study in mice shows that cigarette smoke caused changes in the DNA of sperm cells, the researchers said in this week's issue of the journal Cancer Research. Such mutations, know as germline mutations, are known to be permanent.
Article Summary: Researchers studied the stem cells that produce sperm in mice exposed to cigarette smoke for either six or 12 weeks. All male mammals continuously produce sperm. They found 1.7 times as many DNA mutations in the cells of the smoke-exposed mice as in those of the unexposed mice after 12 weeks, and 1.4 times as many mutations after six weeks.

Science has spoken when it comes to the theory that some childhood vaccines can cause autism. They don't, the Institute of Medicine concluded three years ago. Soon, it will be the courts turn to speak. More than 4,800 claims have been filed against the federal government during the past six years alleging that a child contracted autism as a result of a vaccine. The first test case from among those claims will be the subject of a hearing that was to begin next Monday in a little-known "People's Court" -- the U.S. Court of Federal Claims. A special master appointed by the court will hear the case.
Article Summary: The test case addresses the theory that the cause of autism is the measles, mumps and rubella vaccine in combination with other vaccines containing the preservative thimerosal. That preservative, which contains a form of mercury, is no longer in routine childhood vaccines. However, it is used in influenza vaccines. In July 1999, the U.S. government asked vaccine manufacturers to eliminate or reduce, as expeditiously as possible, the mercury content of their vaccines to avoid any possibility of infants who receive vaccines being exposed to more mercury than is recommended by federal guidelines. One of the parents who has filed a claim against the federal government and has great interest in the case is Scott Bono of Durham, N.C. He said that parents of children with autism have been marginalized, but they see specific outcomes in their children that are consistent with exposure to mercury. And those outcomes did not present themselves until after they received their vaccinations. Autism is characterized by impaired social interaction. Those affected often have trouble communicating, and they exhibit unusual or severely limited activities and interests. Meanwhile, classic symptoms of mercury poisoning include anxiety, fatigue and abnormal irritation, as well as cognitive and motor dysfunction.
Dr. Paul Offit is chief of the division of infectious diseases at the Children's Hospital of Philadelphia. He said epidemiological studies pick up minute, almost invisible differences in the populations that have received a vaccine versus those that have not. For example, a swine flu vaccine in the 1970s caused the sometimes paralyzing Guillain-Barre syndrome in 1 out of 100,000 cases, he said. But no such correlations have been found for autism, which affects about 1 out of 150 children, he said. Offit said mercury is part of the natural environment. There's no escaping it and, in fact, children will get more mercury from breast milk than they get from a vaccine. The report from the Institute of Medicine pointed to five large studies, here and abroad, that tracked thousands of children since 2001 and found no association between autism and vaccines containing the preservative thimerosal.

Article Summary: Few noticed in November when the American Dental Association alerted its members via e-mail of a possible problem with giving babies fluoridated water. The ADA, long among fluoride's biggest advocates, wrote that parents of infants younger than a year old "should consider using water that has no or low levels of fluoride" when mixing baby formula." The issue for the ADA and for babies is fluorosis, a condition caused by too much fluoride that damages the enamel of teeth. In its milder forms, fluorosis causes white specks or streaks to appear. More severe cases involve dark staining and pitting of tooth enamel, which can increase the likelihood of decay and infection. Both sides in the fluoride debate agree severe cases are rarely seen in those whose water is fluoridated at recommended levels. Mild fluorosis is more common and fluoride backers have argued for years that such cases are cosmetic and not harmful. Yet some scientists warn even mild to moderate cases may lead to more significant problems. The Environmental Protection Agency has established federal safety limits for fluoride that naturally occurs in drinking water -- 4 parts per million. The EPA asked the National Research Council to evaluate that limit, and in a report released in March 2006 the council found that the EPA limit is too high and associated with harmful dental effects and an increased risk of bone fractures. The report did not address the safety of treated water supplies, which have much lower concentrations. The report also concluded that additional research was warranted because of previous work that had suggested links between fluoride and lowered IQs in children and bone cancer. Studies done overseas have associated mild to moderate fluorosis with lower IQs, endocrine system problems and skeletal damage. The National Research Council also raised questions about the connection between baby formula reconstituted with fluoridated water and fluorosis. The major portion of the fluorosilic acid added to the nation's water supply comes as a byproduct of Florida's phosphate fertilizer industry.

Article Summary: The lead that recently poisoned a San Joaquin County girl did not come from her house's paint, public health nurse Gale Heinrich said. It came from her tea parties. The glaze in terra cotta pottery contained lead, which leached into the child's drinks. Now the small cup is part of an educational display in Heinrich's north Stockton office. It sits among candies, home remedies, mineral supplements, cosmetics, vinyl mini blinds -- all lead-tainted. Lead poisoning, especially among children, harms mental development. It takes a blood test to detect lead poisoning, and many children show no symptoms. In some cases, a poisoned toddler will have delayed speech, Heinrich said. A school-age child might seem aggressive or have trouble paying attention. Lead poisoning can be treated, but the harm it does to a child's brain can't be reversed.

Article Summary: Flame retardants can be found everywhere: the dust under your couch, the foam in your couch, in your television, your blood, even breast milk. Some evidence suggests children are more contaminated than their parents. More than 56,000 tons were infused into consumer goods worldwide last year, chiefly TV sets. They represent an amazing spectrum of chemistry -- more than 300 compounds, with at least 70 available commercially. One of the most widely used is generating the most heat, with attempts to ban it in various stages of development in California, Illinois, Maine, Washington and Europe. Known as "Deca," it is a close cousin to PCBs and the only one of the flame retardants known as PBDEs, or polybrominated diphenyl ethers, still on the market. Two other PBDEs, "Octa" and "Penta", have been banned in Europe and several states after scientists concluded both compounds were bioaccumulative and toxic. Deca was once thought to be environmentally stable and not readily absorbed but now appears to be both quick to degrade and readily available. There's a lot of evidence that Deca quickly breaks down in the body and the environment to smaller, more toxic compounds -- such as Octa, said Heather Stapleton, an assistant professor at Duke University's Nicholas School of the Environment and Earth Sciences.
Industry groups note that the chemical is astoundingly effective at stopping a very real risk -- fire -- in plastics. Manufacturers don't need much Deca to protect products; plastics with Deca can be readily recycled, unlike those with other additives; the amounts contaminating humans remains, so far, fairly minuscule; and much less is known about alternative flame retardants. The industry maintains that the chemical is largely inert.

Article Summary: Perfluorooctanoic acid (PFOA) shows up widely in people's blood, although the primary route by which PFOA gets into people has been unknown. PFOA, used to manufacture nonstick cookware and rain gear, turns up in blood samples worldwide, reaching concentrations of 30 nanograms per milliliter or more. The chemical doesn't degrade, and people excrete it slowly. Environmental chemists Scott A. Mabury and Jessica C. D'eon of the University of Toronto tested a pathway that begins with related chemicals called polyfluoroalkyl phosphate surfactants (PAPS), substances used to coat oil- and water-repellent food wrappers. Mabury and D'eon have shown that, in rats, not only can the body absorb PAPS, but the chemicals degrade into PFOA, a potentially toxic compound. If PFOA is in people's blood because they make it inside their bodies, says Mabury, then the behavior of the intermediate chemicals in this exposure pathway becomes important as well. Some of these intermediates "have the potential to be far more toxic than PFOA," he says.

Article Summary: The air inside your home can be two to five times as polluted as the air outside, according to the U.S. Environmental Protection Agency. And since people spend as much as 90 percent of their time indoors, the quality of the air can make a big difference in quality of life. Chemicals leached off painted walls and furniture, fumes from cleaning products, mold and noxious gases seeping in from the outdoors are some of the air contaminants that can find their way into your home. Pollutants don't disperse and dilute in a sealed home as they would outdoors. Poor indoor air quality can have a variety of health effects. Asthma, allergies, respiratory problems and heart conditions can be aggravated. Chemicals can irritate eyes and throats. Extreme cases of radon or carbon monoxide contamination can lead to lung cancers and premature death. Indoor air pollution affects the same people affected by outdoor pollution: children, the elderly and people with existing respiratory problems. Severe cases can trouble even healthy adults. Because people spend so much time indoors, and because there's less space for pollutants to dilute, the risk of inhaling some contaminants can be up to 1,000 times higher indoors than outside, according to a 2005 report from the California Air Resources Board on indoor air quality. The Occupational Safety and Health Administration has standards for indoor air quality in workplaces. The state Department of Health Services works with EPA to improve indoor air quality in schools. But regulating household air quality is the responsibility of the homeowner.

MANCHESTER -- The state is raising a generation of sedentary, overweight children who need to get close to nature in order to reverse the trend, state leaders were warned yesterday. More than 100 educators, environmental leaders, the medical community, insurers and landscapers were challenged yesterday to come up with an effective strategy to "Leave No Child Inside."
Article Summary: New Hampshire's first lady Dr. Susan Lynch said Kids are less active than the previous generation and are choosing video games and instant messaging over building forts and catching bugs in a jar. Meanwhile, parents are too busy working to get outside with their kids. Lynch challenged the group to help come up with ideas to encourage outdoor use to promote more healthy lifestyles and connect to nature. Participants said part of the problem is that media portrays woods as dangerous, schools are reducing recess and keeping children inside on cold days, and neighborhoods are being built with small backyards and little access to fields, forests and ponds. National statistics show bike riding is down 31 percent since 1995 and in a typical week, only 6 percent of children aged 9 to 13 play outside on their own. Dr. Cheryl Charles, president of the national Children and Nature Network, said while she would not write off any particular age group, the target is for engaging children in nature is aged 4 to 12. This will help reduce lifelong health problems, increase creativity and help stress reduction.

Article Summary: Amid publicity about mold and its links to severe illness, the issue of mold contamination has drawn the national and international attention. As recently as 25 years ago, inhaled mold was considered primarily a nuisance, not a serious health threat. But the growing scientific and medical evidence suggests the threat is widespread and, for some people, quite serious. In the 9 June 2006 report Mold Prevention Strategies and Possible Health Effects in the Aftermath of Hurricanes and Major Floods, the CDC concluded that "excessive exposure to mold-contaminated materials can cause adverse health effects in susceptible persons regardless of the type of mold or the extent of contamination." But many of the puzzle pieces -- exactly who is vulnerable, to what extent, and under what conditions -- are still missing. The vast information gaps that remain continue to feed significant controversy in the legal, insurance, political, scientific, medical, public health, and building design, construction, management, and maintenance arenas. Molds must have some source of water and food to grow. Problems with mold can surface anywhere in the world after just one or two days of moisture exposure. The same conditions that give rise to mold growth also support many bacteria, and many components and emissions from these fungi and bacteria are known or suspected to harm human health. Mycotoxins have often been the main point of contention in recent insurance claims and lawsuits over suspected harm from moldy buildings. Mycotoxins can elicit responses in almost anyone they come in contact with. The health effects are worrisome, and infants, at least, should be removed from suspect settings.
After reviewing the evidence available by 2004, the Institute of Medicine (IOM) concluded there are moderately strong or at least limited links between damp indoor spaces and a handful of health problems, such as asthma, cough, wheeze, hypersensitivity pneumonitis, and a range of other upper and lower respiratory problems. Other health problems under suspicion include headache, memory loss, nausea, diarrhea, diabetes, fatigue, and fever, although rigorous studies have not been conducted to show the connections. A June 2007 assessment determined that 21% of current U.S. asthma cases may be attributable to dampness and mold in homes, with schools, offices, and institutional buildings playing a similar unhealthy role. In 2006 the American Institute of Architects (AIA) emphasized that design details are critical in preventing mold problems. Another critical area requiring attention is the very limited repertoire of effective medical treatments to prevent illness or treat people experiencing certain ill effects such as allergic bronchopulmonary aspergillosis and acute idiopathic pulmonary hemorrhage, says Lynnette Mazur, a professor of pediatrics at the University of Texas Medical School at Houston.

Stress experienced by a woman during pregnancy may affect her unborn baby as early as 17 weeks after conception, with potentially harmful effects on brain and development, according to new research. The study is the first to show that unborn babies are exposed to their mother's stress hormones at such an early stage in pregnancy. The findings, published in the journal Clinical Endocrinology, come after separate research on animals showed that high levels of stress in a mother during pregnancy could affect brain function and behaviour in her offspring, and other evidence suggesting that maternal stress in humans can affect the developing child, including lowering its IQ. However, the way this happens and the implications for the unborn child, both before and after birth, are still not fully understood and further research is needed, the latest study's authors said.
Article Summary: The research shows that the fetus is exposed to cortisol in the maternal blood, and that at and above 17 weeks, the stress hormone cortisol in amniotic fluid had a strong positive relationship with cortisol in maternal blood. The study authors did not wish to "unduly worry pregnant women", but highlighted the need to lead a "healthy, balanced lifestyle" to avoid general stress. An earlier study, published in January and led by Prof Glover, measured the intelligence of more than 100 babies and toddlers whose mothers had suffered unusually high stress in pregnancy. It found their IQ was generally about 10 points below average, and that many had higher than average levels of anxiety and attention deficit problems. Relationship problems with a partner were the most frequent cause of stress for pregnant women, the research revealed. The findings, the latest to focus on the impact of the environment in the womb on later development, come days after the government changed its advice to pregnant women and those trying to conceive, warning them to abstain from drinking alcohol. Previous guidelines had said they could drink up to two small glasses of wine a week.

Copenhagen, Denmark -- Are a group of modern chemicals present in everyday household products behind increasing rates of breast and testicular cancer, male infertility, diabetes and even obesity? As new regulations on the chemicals, known as endocrine disrupters, go into effect in the European Union today, select scientists from around the globe met to share their research and growing concerns. Some of the chemicals -- found in plastic containers, dental sealants, soda and soup can linings, carpets, paints and pesticides -- remain virtually unregulated in the United States. Europe's new rules require that industries that manufacture or import more than about 2,200 pounds per year of any given chemical will have to provide a risk assessment of that substance. In 2006, the European Union adopted a chemical regulation program called REACH -- Registration, Evaluation, Authorization and Restriction of Chemicals. The program puts the burden of risk management onto industry, and away from regulators. All chemicals will be registered in a central database, overseen by the EU's Chemical Agency. Over a period of 11 years, more than 30,000 chemical substances will be registered.
Article Summary: Of the 30,000 chemicals required for registration, more than 90 percent of them have no data, according to Andreas Kortenkamp, a researcher at the School of Pharmacy at the University of London. Mike Walls, managing director at the Virginia-based American Chemistry Council, called REACH "a very complex and complicated system," and one that is untested. Walls said the U.S. already has the Toxic Substances Control Act enforced by the Environmental Protection Agency, and added, "we think that's working very well." Frederick vom Saal, an endocrinologist at the University of Missouri, expressed concern about REACH for another reason: its reliance on corporations and industry. In a study published in 2005, vom Saal showed that 100% of studies conducted by industry on the safety of bisphenol A, which is an additive in polycarbonate plastics, showed that the chemical was safe, while not one independent government or academic study has come to the conclusion that the chemical is safe, according to vom Saal. This week's workshop in Denmark brought together more than 150 top researchers in the field and focused on new research exploring these chemicals.

Article Summary: Naturally occurring arsenic is a worldwide phenomenon, and scientists and public-health managers from Bangladesh to Nicaragua to New Hampshire have been working on ways to filter out this toxic metal from drinking water. Many filters use iron because it binds arsenic relatively efficiently. Larger-scale filtration plants in developed parts of the world, which process thousands of gallons of water a day, use bits of iron to filter arsenic. But the iron flakes can foul filtering membranes, and getting rid of them is difficult. If the amount of iron used in large filtration plants can be scaled down while maintaining or even increasing the efficiency of arsenic removal, a solution to their arsenic problem would be provided. Nanomaterials could provide that next-step tool in the arsenal against arsenic. Researchers from Rice University have been tinkering with tiny, magnetic iron nanoparticles for just such a treatment process. They have created a filtering system that uses nanoscale magnetite (Fe3O4) to bind both As(III) and As(V), which can then be removed from water with a magnet. The higher surface-to-volume ratio allows for more efficient capture of arsenic by smaller particles. Preliminary tests have been encouraging, and now the team is working to scale up its filter for use in the US and elsewhere. For an individual household, the team projects that 200–500 milligrams of the magnetite nanoparticles would be necessary to treat a liter of water, at "a fraction of a penny a day and less than a kilogram of waste a year."

Exposure to pesticides could lead to an increased risk of contracting Parkinson's disease, a study has found. Researchers discovered that high levels of exposure increased the risk by 39%, while even low levels raised it by 9%. However, the Aberdeen University researchers stressed that the overall risk of developing the disease remained small.
Article Summary: Symptoms of Parkinson's disease often include unsteadiness and tremor in the hands or arms, often alongside difficulties with speech or movement. Other studies have pointed strongly towards exposure to pesticides being involved in some cases, with agricultural workers showing higher rates of the illness. The Aberdeen study, reported in the journal Occupational and Environmental Medicine, involved 959 cases of parkinsonism, a term used to describe people with diagnoses of Parkinson's Disease, and other, similar conditions. Subjects answered questions about their lifetime occupational and recreational exposure to a variety of chemicals, including solvents, pesticides, iron, copper and manganese, plus whether they had ever been knocked unconscious and more general questions about family health history and tobacco use. All the replies were then compared to those from a group of people of similar age and sex who had not been diagnosed with Parkinson's. While having a family history of Parkinson's was the clearest risk factor for developing the disease, exposure to pesticides also gave a clear increase. Dr. Finlay Dick, the lead researcher, said, "This doesn't prove that pesticides cause Parkinson's Disease, but does add to the weight of evidence of an association." A spokesman for the Parkinson's Disease Society echoed this: "The important finding from this study is confirmation that Parkinson's is not caused by any one factor, but instead a combination of genetic susceptibility and environmental factors."
