1. Environment Agency Invites Nanotechnology Talks

SOURCE ICIS Chemical Business Americas, v270 n16, October 30 - November 5, 2006, p14

ABSTRACT The EPA (Environmental Protection Agency) has invited more than 500 organizations and individuals to take part in a public consultation on the risks and benefits of nanotechnology. The EPA will use the consultation to design and develop a stewardship program. The EPA said the program will complement new and ­existing chemical initiatives under the Toxic Substances Control Act, and will provide a "firm scientific foundation for regulatory decisions." The EPA added that its nano­technology program was set to include public and scientific consultations to discuss risk-management practices and characterization of nanoscale materials, and workshops examining the pollution prevention opportunities for nanoscale materials. Representatives from industry, environmental groups and federal agencies have been invited to take part in the consultation process.


2. Business and Ecosystems: Ecosystem Challenges and Business Implications

DATE 2006

SOURCE Earthwatch Institute; IUCN; World Business Council for Sustainable Development; World Resources Institute

ABSTRACT Over the past 50 years human activity has altered ecosystems faster and more extensively than ever before in human history. That is the main finding of the Millennium Ecosystem Assessment (MA), a four-year, international, scientific appraisal of the condition and trends in the Earth’s ecosystems. The MA classified ecosystem services, the benefits people and businesses obtain from ecosystems, into four categories:  Provisioning – goods such as food, water and fiber;  Regulating – biophysical processes controlling natural processes;  Cultural – providing recreational, aesthetic or spiritual values;  Supporting – underlying processes such as soil formation, photosynthesis and nutrient cycling. The MA assessed 24 ecosystem services and found the majority to be degraded. The MA2 also identified six interconnected challenges that are of particular concern for business as these further affect the integrity of ecosystems and their capacity to provide services:  Water scarcity;  Climate change;  Habitat change;  Biodiversity loss and invasive species;  Overexploitation of oceans;  Nutrient overloading. This Issue Brief explores the six challenges, discusses their implications for businesses and provides examples of corporate responses.

3. Environmental and Occupational Causes of Cancer Re-visited

AUTHOR Clapp, Richard W.; Howe, Genevieve K.; Jacobs, Molly

SOURCE Journal of Public Health Policy, v27 n1, April 2006, pp61-76

ABSTRACT We recently completed a review of scientific evidence, particularly epidemiologic evidence, regarding the contribution of environmental and occupational exposures to the overall cancer burden in the US. We evaluated the efforts to estimate the proportion of cancer due to these involuntary exposures, including the ambitious effort by Doll and Peto and an update by a group of authors at the Harvard Center for Cancer Prevention. In this paper, we critique these efforts, and their resulting estimates of the proportion of cancer due to various factors. We also provide an alternative interpretation of the evidence and a caution against the very idea of attributing specific fractions or proportions of cancer to particular factors. We conclude by recommending that environmental and occupational links to cancer be given serious consideration by individuals and institutions concerned with cancer prevention, particularly those involved in research and public education. We support the new initiative in the European Union to evaluate chemicals more fully before they reach the market.


4. EPA Qualification Helps Cytec Market Eco-Friendly Products

SOURCE PCI Paint & Coatings Industry,v22 n11, November 2006, p21

ABSTRACT Cytec Industries Inc., a global specialty chemicals and materials company, was recently named as the first company to qualify for the U.S. Environmental Protection Agency’s (EPA) Sustainable Futures program, which includes approval for a shortened regulatory review process for certain new products. As a result, the EPA’s Pre-Manufacturing Notice review period for Cytec products assessed as low overall risk will be halved from the minimum of 90 days to only 45 days, thus increasing the speed at which eco-friendly products can reach the marketplace.

5. Environment Matters at the World Bank: Good Governance and Environmental Management

DATE 2006

SOURCE World Bank

ABSTRACT Strengthening governance is now an integral component of the World Bank’s approach to development assistance. Symptoms of weak governance include problems with the distribution of revenues, non-payment of taxes, restricted entry and competition in markets, questionable quality of the regulatory framework, poor control of corruption or graft, questionable attention to civil liberties, transparency and accountability, and instability or violence and crime. It is impossible to determine the developmental cost of poor governance, but world-wide bribery alone is estimated to exceed $1 trillion dollars annually. The management of water, forests, fisheries, wildlife, and other natural resources is too often subject to poor governance, which contributes to degradation—such as depleted soils, insufficient and polluted water, rapidly disappearing forests, and collapsed fisheries— and threatens the health and livelihoods of millions of people. These problems are particularly acute in poorer countries, in which people are most dependent on their natural resource base. In many developing countries, the costs of environmental degradation have been estimated at 4 to 8 percent of GDP annually. Yet such resources are a vital part of these countries’ overall wealth. The World Bank’s recent Wealth of Nations found that in poor countries (excluding oil states) natural resources make up 25 percent of total wealth, compared to 16 percent for produced goods and services. The central focus of the World Bank’s Environment Strategy and program is to promote poverty reduction while managing this natural wealth for current and future generations. This past year, the World Bank launched, in collaboration with donors, NGO partners, and other international organizations, a global program on sustainable fisheries—PROFISH. This initiative focuses on facilitating stakeholder dialogue, providing technical assistance and policy advice, and enhancing fisheries sector capacity and skills. In addition, the World Bank’s forest program is supporting regional forest governance activities to curb illegal logging and support the development of a more level playing field among legitimate forest operators.

6. Pure carbon nanotubes pass first in vivo test

SOURCE Rice University News & Media Relations, November 27, 2006

ABSTRACT In the first experiments of their kind, researchers at Rice University and The University of Texas M. D. Anderson Cancer Center have determined that carbon nanotubes injected directly into the bloodstream of research lab animals cause no immediate adverse health effects and circulate for more than one hour before they are removed by the liver. The findings are from the first in vivo animal study of chemically unmodified carbon nanotubes, a revolutionary nanomaterial that many researchers hope will prove useful in diagnosing and treating disease. The research will appear in this week's online edition of the Proceedings of the National Academy of Sciences. "We sampled tissues from a dozen organs, and found significant amounts of nanotubes only in the liver," said lead author Bruce Weisman, professor of chemistry. "The liver naturally removes drugs or compounds from the blood, so this is what we expected to find." The study, which tracked where the nanotubes went within 24 hours of being injected, also revealed trace amounts of nanotubes in the kidneys – another common expulsion route for drugs. There was no evidence that nanotubes remained in other tissues in the body. Nanotubes are hollow cylinders of pure carbon that measure just one nanometer in diameter – about the same width as a strand of DNA. Nanotubes have unique chemical and optical properties, and they have attracted intense interest from biomedical researchers. "The early results are promising for anyone interested in using carbon nanotubes in biomedical applications," said co-author Dr. Steven Curley, professor of surgical oncology and chief of gastrointestinal tumor surgery at M. D. Anderson. "We are particularly pleased that the fluorescent effect remains intact in our application, because this makes it easier to see where the nanotubes end up, and it opens the door to some exciting diagnostic and therapeutic applications." In a 2002 study, Weisman and colleagues at Rice, including the late Professor Richard Smalley, discovered that nanotubes fluoresce, or emit near infrared light. Because near-infrared light passes harmlessly into the body, biomedical researchers are keen to use carbon nanotubes for the noninvasive diagnosis and treatment of diseases such as cancer and atherosclerosis. In the current study, Weisman, Curley and colleagues injected lab animals with water soluble single-walled carbon nanotubes. The nanotubes, whose biocompatible coating was displaced by proteins in the blood, continued to fluoresce in the animals.

7. Environmental justice and toxic exposure: Toward a spatial model of physical health and psychological well-being

AUTHOR Bevc, Christine A.; Marshall, Brent K.; Picou, J. Steven

SOURCE Social Science Research, v36 n1, March 2007, pp48-67

ABSTRACT The relationship often assumed by environmental justice researchers is that proximity to a hazardous waste site is a measure of exposure to harmful chemicals. Few researchers, however, explicitly address the methodological challenge of measuring the causal relationship between toxic chemical exposure and health problems. To better understand the methodological task of moving beyond the proximity-exposure assumption, the three most commonly used quantitative methodological approaches in environmental justice research are briefly outlined. Using geographic information system techniques, we operationalize toxic exposure as an interval-level variable and integrate this data with geocoded health and social survey information. We develop a methodological design that enables researchers to assess what factors cause mental and physical health problems for individuals living in contaminated areas. The results of the hierarchical multiple regression analyses indicate that sociodemographic, perceived exposure, objective exposure, and food consumption variables are significant predictors of physical health and psychological well-being. We also found a significant relationship between physical health and psychological well-being. The data used in this paper were collected in a low-income, African-American community in Fort Lauderdale, Florida. This community is contiguous to a Superfund site (EPA) called the Wingate Road Municipal Incinerator and Landfill.


8. Persistently Clean?

AUTHOR Brodie, Christopher R.

SOURCE American Scientist, January-February 2007

ABSTRACT More than a million pounds of antimicrobial chemicals from soap and other products flow into the nation's sewers every year. Do these compounds pose a risk? Product manufacturers say no, pointing to data that show only traces of the two most common antibacterials, triclosan and triclocarban, in treated wastewater. What happens to the remainder is less certain. The stock explanation has been that the majority is broken down during the treatment process. The fraction released into surface water was thought to meet the same fate sooner or later. Thus, much of the claim that these products are safe rested on the fact that they were rendered harmless in treatment plants or just beyond. New data puncture that conclusion: 50 percent of triclosan and 76 percent of triclocarban remain unchanged by aerobic and anaerobic digestion in a typical wastewater facility, according to a pair of recent reports. This large intact fraction isn't going out with the treated water—the old estimates are correct in that respect. Rather, it is trapped in the sludge at the bottom of the treatment tanks. Most of that sludge gets spread on the ground to fertilize pasture, forests and human food crops. Triclosan and triclocarban are small organic molecules that give antimicrobial properties to personal-care products such as soap, deodorant and toothpaste as well as durable goods such as cutting boards, baby carriers and socks. Overall, Halden's team estimates that more than 100,000 pounds of triclosan and over 300,000 pounds of triclocarban are spread on the ground as sludge each year in the United States, based on data from a dozen sites around the country. Of the total mass that enters a typical sewage-treatment facility, two percent of triclosan and three percent of triclocarban remain in the clean-water output. Thus, only 48 percent of triclosan and 21 percent of triclocarban are transformed or lost in the treatment process—much less than industry estimates. At 50 and 76 percent, respectively, sludge is the biggest repository.

9. Water Use Reduction at an Auto Assembly Plant

DATE 2006

SOURCE Illinois Waste Management and Research Center (WMRC)

ABSTRACT Misunderstanding the true cost of utilizing raw materials such as water can frequently result in poor management choices regarding how the raw materials are used. Metal finishing operations are notorious for using large quantities of water in their processes. The common perception is that “water is cheap” so, it can be used liberally to ensure that work-pieces are adequately cleaned, rinsed and coated. While it may be true that the actual purchase of the water itself is relatively inexpensive, the cost to using the water within the processes may be considerably more expensive. A 2004 assessment performed by the Illinois Waste Management and Research Center on a major automotive assembly plant’s phosphating processes revealed that they perceived their water costs to be only $2.20 per 1,000 gallons (the cost to purchase water from the city). At this low cost, water was used liberally throughout the plant to ensure adequate quality of cleaning and coating processes. Consequently, conservation measures were difficult to justify from an economic standpoint. However, when the process was broken down on a step-by-step basis and all costs associated with using the water were considered, it was concluded that the true cost of using the water was much higher. Including the value of process chemicals, energy, water purification measures, and wastewater treatment in the total cost of using water, increased the average cost to $80 per 1,000 gallons (a 36 fold increase). Prior to performing this analysis, the plant had been using about 90 million gallons of water annually because they perceived that water was cheap and conservation measures were not warranted. They estimated that the water cost them about $200,000 per year. The results of the assessment showed them that using this quantity of water was actually costing them over $7 million dollars per year.

10. Inquiry Turns To Humans On Pollutant, Hormone Tie

AUTHOR Fahrenthold, David A.

SOURCE Washington Post, December 4, 2006

ABSTRACT Growing evidence that chemicals in the environment can interfere with animals' hormone systems -- including the discovery that male Potomac River fish are growing eggs -- has focused the attention of environmentalists and scientists on a new question: Are humans also at risk? In recent years, researchers have linked some common chemicals to troubling changes in laboratory rodents and wild animals, including reproductive defects, immune-system alterations and obesity. For now, no connections to human ailments have been proved. But some studies have provided hints that people might be affected by crossed hormones, and activists wonder if this kind of pollution could contribute to diabetes, birth defects and infertility. "There's a lot of concern that a lot of chemicals to which we are exposed routinely, and without our knowledge, are interfering with the way hormones work," said R. Thomas Zoeller, a professor of biology at the University of Massachusetts at Amherst. In the past few years, scientists working with animals have found potential problems with several pollutants, among them rocket-fuel components, pesticides and additives to soap. Among the most heavily researched: * Phthalates, a family of additives used to make vinyl plastic flexible and prevent perfume from evaporating, have been linked to lower sperm counts and other sexual problems in male rats, as well as to heightened allergic reactions in the animals. Chemical industry officials have said that these tests used unrealistically high doses and that the results are not likely to translate to humans. * Bisphenol A, used as a building block for hard plastic goods like bottles and as a resin to line food cans, has been connected in some experiments to abnormal sexual development in male lab rodents, as well as a predilection for obesity. Officials from the chemical and pesticide industries have vigorously criticized these results, saying that other studies have shown the chemical to be harmless. * Treated sewage, which carries human estrogen and birth-control pill components excreted in waste, has been linked to "feminized" male fish in waters around the world. In the St. Lawrence River in Canada, a recent study found that a third of male minnows had female characteristics. Another example might be the Potomac, though the cause of its problems has not been officially pinpointed. The EPA and sewage-plant officials have said they are working on ways to better clean the wastewater.
