This brown bag will present information on the European Union regulatory framework for the Registration, Evaluation and Authorisation of Chemicals (REACH). DTSC has invited Mr. Todd O. Maiden and Dr. David Eastmond to speak about the European Union regulatory framework for REACH. REACH will require manufacturers and importers to gather information on the properties of their substances and register the information in a central database. A European Chemicals Agency will be established to manage the databases needed to implement REACH, to coordinate the evaluation of chemicals of concern and to create a public database in which consumers and professionals can find hazard information. Mr. Maiden is a partner in the ReedSmith environmental and energy practice group with experience in international environmental issues including climate change and ISO 14000. Dr. Eastmond is with the Department of Biochemistry at the University of California Riverside. Dr. Eastmond's laboratory researches the mechanisms involved in the toxicity and carcinogenesis of environmental chemicals.

When parents first hear that some plastics may be a threat to their children's health, their initial reaction is often disbelief. "Surely the government tests these materials thoroughly for safety."
No, it doesn't.
Then, when they learn that a common component of plastic toys and food containers, bisphenol A, has been shown by many studies to cause harmful effects, some respond, "Surely those impacts are because of high doses, not what my child would encounter."
No, they're not high. The doses used were in the range of common human exposure.
More than 40 independent studies of bisphenol A exposures at daily exposure levels below what the U.S. Food and Drug Administration says is safe cause adverse effects in rodents when exposed in the womb.
Bisphenol A is used to make polycarbonate plastic, a common component of children's toys, most baby bottles, and some wildly popular water bottles. It's also used to make an epoxy lining for food and beverage cans. While superficially it appears to be stable, the plastic readily degrades and age and heat accelerate the degradation. Thus, use virtually guarantees exposure.
Fifteen years ago, toxicologists would have scoffed because the resulting exposures are low. That was before many scientists began to understand that some chemicals, such as bisphenol A, mimic the sex hormone estrogen. Now thousands of scientists around the world are studying the impact of exposure to these man-made sex hormones that leach out of everyday household products and toys. The results are disquieting. Contaminants such as bisphenol A can cause effects at extremely low levels, below 1 part per billion, which is within the range of common human exposures.
Sex hormones aren't just about sex and teenagers. Sex hormones are vital signals the body uses to guide how a fetus develops. The wrong amount of hormone, or hormone-like chemical, at the wrong time can have a disastrous impact on a developing fetus or child. The last 10 years of research has provided extensive evidence that this is true for bisphenol A.
In animal experiments, university scientists have now linked early bisphenol A exposure to prostate cancer and breast cancer in adulthood, attention disorders, changes in behavior, elimination of brain differences between males and females, disruption of insulin regulation (which leads to diabetes) and an increase in body weight, chromosomal damage in the eggs of female babies (which usually means their embryos are miscarried), reduced sperm count and infertility. Scientific bodies in the federal government have concluded that animal studies are a vital guide to identifying health risks for humans, because the molecular mechanisms causing the response to bisphenol A are fundamentally the same.
This substantial scientific literature has yielded important lessons. Most important, these effects are seen at levels to which people are commonly exposed by using consumer products made out of bisphenol A.
A big surprise has been that the high dose experiments that we have depended upon to tell us what is safe simply don't work with hormone mimics such as bisphenol A. High doses of hormones can cause very different effects than low doses. The standard tests used in toxicology to set health standards have ignored those low-dose impacts, instead assuming that the dose makes the poison. This new generation of science directly challenges that assumption. Another key finding has been that early-life exposure can have catastrophic consequences for later adult health.
One other lesson has emerged. More than 90 percent of publicly funded studies show bisphenol A causes adverse effects at low levels. Not one study funded by the chemical industry finds harm.
So far, only a handful of human studies have been guided by these lessons. As the studies continue to mount, what are our choices? In the interest of protecting its youngest citizens, the City of San Francisco has taken an important first step by proposing a ban on products for infants that contain bisphenol A. San Francisco's leaders should stay the course. There are replacements for bisphenol A. The same can't be said for children's health.

A national controversy over cutbacks and outright closings of Environmental Protection Agency libraries came to Seattle over the weekend as librarians from around the country told EPA officials the agency is undercutting its own workers, its scientists and the public. Across vast stretches of the heartland, EPA scientists, university researchers and others have scrambled to locate documents once easily found by librarians in the agency's regional headquarters, said participants in the America Library Association annual conference.
Article Summary: The EPA libraries were well used. Internal EPA documents obtained by the Seattle P-I show that more than 20,000 requests for quick reference and another 20,000-plus requests for extended research were filled by EPA librarians in fiscal year 2005, the latest statistics available. The figure for database and literature searches exceeded 85,000. EPA libraries have been closed in Chicago, Kansas City, Dallas and Washington, DC, as well as the EPA's headquarters library. Hours have been reduced in Boston, New York, San Francisco and Seattle. With a congressional investigation pending, agency officials responded that they are merely trying to move the EPA libraries' contents onto the Internet, where people worldwide can use them more readily. However, nearly all the documents not actually written by the EPA would not be put online because of copyright restrictions, according to EPA officials.

http://www.usatoday.com/news/washington/2007-01-21-rail-cargo_x.htm
WASHINGTON -- The government for the first time will monitor rail shipments of potentially deadly cargo passing through cities to make sure cars vulnerable to attack don't sit unguarded for too long. The Transportation Security Administration (TSA) will start a nationwide tracking system in about a month to determine how long rail cars filled with lethal materials are stopped on tracks or sit in unsecured storage yards in urban areas. Unguarded rail cars filled with toxic chemicals such as chlorine in cities are the single biggest terrorist threat related to the nation's railroads, the TSA says.
Article Summary: Railroads carry 105,000 carloads of toxic chemicals a year, and 1.6 million carloads of other hazardous materials such as explosives and radioactive items, the government says. The U.S. Naval Research Lab has said an attack on such a rail car could kill 100,000 people. The new tracking system lets the TSA enforce an agreement that aims to reduce by 25% this year the number of hours hazardous rail shipments sit unguarded in each of 46 major urban areas. The tracking comes as cities consider banning or restricting hazardous rail shipments. Local officials fear attacks and accidents like the fiery train derailment Tuesday near Louisville that spewed toxic smoke and forced people from homes, businesses and a school. Rail companies fear such laws would force them to send hazardous cargo hundreds of miles around cities. CSX Transportation blocked a Washington, DC, ordinance with a lawsuit that is pending. TSA chief Kip Hawley said barring hazardous rail cargo from cities could force it onto trucks, which are more easily attacked and accident-prone.

Article Summary A mass study of the long-term impact of mobile phones is to be undertaken amid fears that people who have used them for more than ten years are at greater risk from brain cancer. More than 200,000 volunteers, including long-term users, are to be monitored for at least five years to plot mobile phone use against any serious diseases they develop, including cancer and Parkinson's and Alzheimer's diseases. Professor Lawrie Challis said that research has shown that mobiles are very safe in the short term but that there is a "hint of something" for people using them longer. He said that the study was necessary because all the important breakthroughs in what caused cancers had shown that the effects often took more than ten years to show. "You find absolutely nothing for ten years and then after that it starts to grow dramatically." Andrew Lansley, the Shadow Health Secretary, said: "It's not scare-mongering to ask these questions for future generations. At the moment there is little evidence to suggest that use of mobile phones has any impact on health, but it is vital that there is continuing research to establish if long-term use is a danger."

For decades, researchers largely assumed that a poison's effects increase as the dose rises and diminish as it falls. However, scientists are increasingly documenting unexpected effects -- sometimes disproportionately adverse, sometimes beneficial -- at extremely low doses of radiation and toxic chemicals.
Article Summary: For example, A German team recently found that in newborn male rats, the lowest di-2-ethylhexyl phthalate (DEHP) doses tested suppressed the brain activity of an enzyme critical for male development. This was a surprise because higher DEHP doses stimulated that enzyme's action. Other toxic agents have unexpectedly beneficial effects. X-rays and gamma radiation are well-recognized carcinogens. However, a growing body of animal data now indicates that lower radiation exposures can defend against cancer-inducing biological changes. Many such effects have been overlooked because researchers prematurely stopped probing for biological impacts as soon as they identified dosage levels of a poison that appear benign, says toxicologist Edward J. Calabrese of the University of Massachusetts-Amherst. In a related class of nonlinear effects, called hormesis, a compound at high doses has an inhibitory -- and generally toxic -- effect on some biological process but the opposite effect at certain low doses. Recent work by Calabrese shows measurable biological effects at low doses appear to be more the norm than an anomaly. Although most toxicologists today agree that hormesis occurs, some argue that Calabrese and his team greatly overstate its frequency. Knowledge about low-dose effects has important implications in both medicine and chemical regulation.

Article Summary: The University of New Hampshire and Columbia University began project SPARK -- Strategic Plan for Arsenic Research in Kids -- in 2000. SPARK, funded by the National Institutes of Health, will test private well water in four New Hampshire school districts to determine whether there is a correlation between arsenic levels in the drinking water and a child's ability to learn. Arsenic is a naturally occurring element in the ground. The research team plans to find 500 students who typically drink from private wells and ask them to answer questionnaires. The team will also talk to parents, analyze the components of private well water and perform intelligence tests on the children. Although past studies have shown arsenic impairs motor functioning, researchers are still unsure how much arsenic it takes to hinder intellectual development or how significant arsenic is to development when compared with nutrition and health care and how often a parent reads to their child. The study will take about 18 months.

Article Summary: Bangor is banning smoking in cars if children are present in an ordinance that allows police to stop cars if an adult is smoking while a child under 18 is a passenger. The smoker can be fined $50. While some people liken the situation to "smoke police" or the Gestapo, some smokers conceded that smoking is not good for children. Bangor's ban is part of a much larger movement toward outlawing smoking near children, even in private areas. Arkansas, Louisiana and Puerto Rico recently enacted similar bans, and at least three other states are considering them: California, Connecticut and Maine. At least seven states, including several with large numbers of smokers like Texas, Oklahoma and Alaska, prohibit or sharply restrict smoking around foster children in homes, cars or both. Some require homes or cars to be smoke-free for 12 hours before a foster child enters. Judges determining parental custody and visitation have, in more than a dozen states, ordered a parent not to smoke around a child. An Ohio court last year gave custody of a 6-year-old boy to his father solely because the boy's mother and her fiance smoked. A recent ruling in a New York case said landlords who allow tenants to be exposed to secondhand smoke could be violating obligations to make apartments habitable. The efforts have gained steam from a 2006 surgeon general's report that strongly indicted secondhand smoke, especially for harming children.

Cellphones that contain toxic chemicals are still being sold in Latin America and other developing regions. But thanks to strict European regulations, there are progressively fewer phones being made with cadmium, lead and other dangerous materials. The new, stricter standards -- adopted by the European Union in 2006 -- forced the world's five leading cellphone manufacturers to eliminate toxic metals and other materials from their products.
Article Summary: A cellphone can contain between 500 and 1 000 components. Many of these contain toxic heavy metals such as lead, mercury, cadmium and beryllium, and hazardous chemicals such as brominated flame retardants (BFRs). Polluting PVC plastic is also frequently used to make the case and keypad, and the batteries contain cadmium, nickel and lithium. The EU's Restriction of Hazardous Substances (RoHS) directive entered into force at mid-year, banning the use of a number of hazardous substances such as lead, mercury and BFRs in electrical and electronic equipment. In the EU, all cellphone companies are also obligated to set up take-back and recycle programs for batteries and phones under the bloc's Waste Electrical and Electronic Equipment directive that entered into force in 2005. Reuse of discarded phones is gaining attention. Potentially, tens of millions of old cellphones will be collected and sent to a company in Michigan called ReCellular, which sorts the phones, erases all data contained in their electronic chips, and cleans, tests and resells them. It would be too complicated to manufacture cellphones to meet different standards, so the big companies are making all their cellphones meet European regulations, which are the toughest in the world, according to Zeina Alhajj, a toxics expert with the environmental watchdog Greenpeace International.

The debate over whether plant-derived products are better for the environment than their petroleum-based counterparts has centered on the amount of energy that goes into growing the crops and making the products as well as the greenhouse gases that result from burning fuels. New research published today is the first to quantify the environmental impacts of the fertilizers, pesticides, and equipment that are used in soybean and corn agriculture. The work suggests that policy makers should rethink the benefits of bio-based fuels and plastics.
Article Summary: Compared with petroleum-based products, ethanol and biodiesel are considered "green" because they emit fewer greenhouse gases and they come from plant sources, even though studies have shown that their production may require more fossil fuels. But the environmental impacts of these products are not limited to global warming, says Amy Landis, a civil engineering graduate student at the University of Illinois at Chicago and a coauthor of the paper. Chemicals and heavy machinery used in soybean and corn farming could adversely affect soil, groundwater and air quality. Landis and her colleagues compiled an expanded data inventory for use in bioproduct life-cycle assessments (LCAs) by including the flows of nitrogen, phosphorus, pesticides, and U.S. EPA criteria air pollutants such as nitrogen oxides, sulfur dioxides, and volatile organic compounds. Most inventories have overlooked these compounds. Biofuels have environmental benefits at the global scale and in urban areas, where they reduce smog precursors, according to Thomas Seager, a civil engineer at Purdue University, but "environmental costs may be felt in the [crop] production states."

The cost of controlling mercury from coal-fired power plants can be up to 50% less than the 1999 baseline estimates, according to an economic analysis from the U.S. Department of Energy (DOE). The new report focuses on a well-known technology, activated carbon injection (ACI), and has sparked interest from electric utilities and environmental advocates who sparred over EPA's Clean Air Mercury Rule (CAMR) when it was released in 2005.
Article Summary: The economic analysis shows that the costs of controlling mercury with ACI are as much as 50% less, plus or minus 30%, than what was predicted in 1999. Pilot tests showed very good results even with western coals once the researchers impregnated powdered activated carbon with bromine. "The paper clearly illustrates what technology vendors and environmental groups have been saying all along, that this technology is relatively inexpensive and it's very efficient," says Martha Keating, associate in research with the Children's Environmental Health Initiative at Duke University School of the Environment and Earth Sciences. One electric utility officer, who did not want to be named and who works for a large U.S. company, stressed that the cost estimates have a wide range; are very plant-specific; and depend on a variety of inputs, including the amount of carbon that is injected, the type of coal that is burned, the efficiency and size of the plant, and the electricity demand. "It's very hard to make a general statement of how much this will cost" at every plant, the utility representative says.
Coal-fired plants are the largest single source of mercury emissions nationally and emit 48 tons (t) of mercury annually, according to DOE. The CAMR requires power plants to control mercury emissions to achieve a nationwide reduction of 38 t beginning in 2010 and an additional cut of 15 t by 2018. The final CAMR includes a controversial cap-and-trade system, which allows power plants that reach emissions levels that are below their targets to sell emissions credits to other plants. Plants that purchase credits can use them to meet their emissions caps without reducing mercury. Sixteen states have sued EPA over CAMR, charging among other things that because some plants won't control mercury, hotspots with high levels of mercury will develop or be exacerbated. Fifteen states have already finalized mercury control rules that are stricter than EPA's, and eight more states have tough mercury programs in the works, according to the National Association of Clean Air Agencies.

Several decades ago, industrial sites in the U.S., such as waste incinerators and paper pulp plants, spewed dioxins and related compounds into the atmosphere, polluting rural and urban areas alike. Years after regulations resulted in reduced emissions from those sources, cities have stepped in to become the latest suppliers of the toxic contaminants in rural air, according to new research published today.
Article Summary: Scientists predicted that levels of dioxins and PCBs would drop significantly following Clean Air Act requirements to control the releases of these contaminants from industrial sites. Levels did drop initially, by 1998, the contaminants leveled out in the atmosphere. David Cleverly of the U.S. EPA and his colleagues measured polychlorinated dibenzo-p-dioxins (PCDDs), dioxin-like polychlorinated dibenzofurans (PCDFs), and coplanar PCBs for four and a half years beginning in 1998. Dioxins appear to be spreading outward relatively quickly from urban centers. Previous research suggests that during cooler weather, humans burn more fossil fuels and engage in other activities that increase ambient levels of potentially cancer-causing chemicals which are eventually sequestered in animal fats. The EPPA team confirmed a slight increase in dioxins in winter and a decrease in summer, particularly in northern latitudes. Cleverly and co-workers, however, suggest that winter conditions dampen the atmospheric chemical reactions of hydroxyl radicals with dioxin and photolysis of the dioxins, leaving more of the compounds intact in winter air. The yearly stability of dioxin and PCB concentrations shows that the U.S. may have reached the limits of emissions controls on industrial plants and sites. "EPA has been very good at reducing emissions from big plants, and they are now much more diffuse: general traffic, household burning of waste and wood," and other "not very strong point sources," according to Rainer Lohmann of the University of Rhode Island.

Scientists have long suspected that dust can play a major role in people's uptake of polybrominated diphenyl ether (PBDE) flame retardants.
Article Summary: New research published today is the first to definitively link the PBDE concentrations found in people with the quantities of the persistent, bioaccumulative, and toxic (PBT) contaminants in dust from their homes. A team from Boston University's School of Public Health led the international study, which involved collecting breast milk samples from 46 first-time mothers in the Boston area. Although the researchers obtained dust samples from only 11 homes, they found statistically significant correlations between the levels of PBDEs in the dust from women's homes and the concentrations of the contaminants in their milk. When considered in tandem with the U.S. EPA's new assessments of PBDEs and data on the high concentrations of the contaminants in the dust of some U.S. homes, the findings suggest that children could be exposed to levels that put them at risk of developing neurological problems. The EPA's Integrated Risk Information System (IRIS) draft assessments for PBDEs were released last month, based on research showing neurotoxic effects on developing animals. Heather Stapleton of Duke University, calculates that children living in homes with high levels could be getting PBDE levels higher than the IRIS estimates. The new research does not pinpoint the source of the PBDEs found in the dust. The study questionnaire included detailed questions about potential sources of PBDEs, such as electronics, and furniture likely to contain foam-padding. No relationship was found based on is known about how PBDEs are used in household products. The paper also raises questions about how much dust people take up. The public comment period for the PBDE IRIS documents ends on February 5.

AUGUSTA -- Amy Graham of Farmington lobbied the Legislature three years ago to get rid of potentially harmful flame retardants used in common household items. She's back again this year to finish the job. Graham, the mother of two young children, said Tuesday that she wants the Legislature to prevent new uses of a flame retardant called Deca. It's used in mattresses, televisions, curtains and upholstered furniture to reduce the spread of flames in a fire. In 2004, the Legislature voted to phase out two other forms of the chemicals, called Penta and Octa. Now, Graham and nearly two dozen environmental groups across the state are working to get rid of Deca.
Article Summary: The chemical, which was classified as a "potential human health risk" by scientists at the University of Southern Maine, has been found in human blood and breast milk, according to Graham. Graham was one of many people who came to the Statehouse on Tuesday for a press conference to talk about six environmental goals for the new legislative session. In addition to the bill to prevent new uses of Deca, the 22 groups -- which include the Sierra Club, Northern Forest Alliance and Maine Rivers -- have joined together to support a variety of bills:
