STOCKTON - Parents have the right to know when pesticides are sprayed at many private day-care centers under a state law that took effect Monday.
Article Summary: Pesticides are chemicals used to control weeds, insects, rodents, and other problems such as mold and mildew. They are potentially dangerous to anyone who lives, works or plays where they are applied. But children might be most vulnerable as their bodies grow. Nearly two-thirds of children up to age 5 receive care from someone other than their parents, and a federal study showed levels of pesticides found in dust were higher at day-care centers than in private homes. The new California law requires that notices must be posted in advance of spraying, and day-care centers must keep records of pesticide use for four years. The law affects about 600 day-care centers statewide but excludes small, in-home family day-care centers. The state must promote alternative ways of treating pests.

Lead toxicity is not a problem of the past, nor is it the exclusive domain of children. In fact, lead continues today to pose a serious threat to the health of many U.S. adults.
Article Summary: Since was removed from gasoline, food cans, and other products in the 1970s and early 1980s, environmental lead levels have dropped, and The National Health and Nutrition Examination Surveys have shown that average adult blood lead levels have declined from about 15 µg/dL in the 1970s to today's 1-2 µg/dL. But there are still pockets of high exposures, such as among workers in certain industries, including lead mining, refining, and smelting; construction work involving paint removal, demolition, and maintenance of outdoor metal structures such as bridges and water towers; auto repair; and battery manufacturing and recycling. As far back as 1990, studies have suggested that significant health effects happen at levels below those allowed by OSHA. Now scientists say the evidence is overwhelming that action needs to be taken to further reduce lead exposures in both the workplace and the general environment. The most recent evidence from epidemiological and toxicological studies suggests that low levels of exposure can, over time, damage the heart, kidneys, and brain. Improvements have been made in measurements of both lead exposure and lead's health effects. Increases in both bone lead and blood lead appear to be associated with possibly dangerous increases in blood pressure, and lead is also associated with increased mortality from diseases of the heart. Kidney function may be altered at the lowest levels of blood lead studied to date in relation to renal effects, and lead's effects on the kidneys are thought to play a major role in its effect on blood pressure. Some studies of lead workers have shown associations between blood lead concentrations of 20 to 40 µg/dL and subclinical cognitive decline, including changes in memory or mental processing speed that are measurable but don't put an individual outside the normal range of function. Declines in cognitive function are more likely to be associated with lower-level environmental exposures over time, rather than recent acute exposures. A link between lead exposure and brain cancers is less clear.
Current research hasn't been able to determine a threshold for many of lead's effects, a level below which no effect occurs. Subgroups especially vulnerable to the effects of low-level lead exposure are pregnant women -- whose exposure may affect their offspring's cognitive function -- and people with metabolic syndrome, a cluster of conditions including obesity, high blood sugar, and high blood pressure. People with certain genetic susceptibilities might constitute another vulnerable group. Work is needed to find effective and safe interventions for lowering lead exposure at a population level for people whose blood lead levels are already below 10 µg/dL.

How much of a dangerous chemical is safe to drink? The answer to that question is something two states -- California and Massachusetts -- don't agree upon. A new study by Centers for Disease Control and Prevention scientists has put California on the defense for its reliance on an older, smaller-scale study. The dangerous chemical in question is perchlorate, which has been found in drinking water wells throughout the Inland Empire.
Article Summary: Used in the production of products such as rocket fuel, explosives and fireworks, perchlorate can harm humans by interfering with the functioning of the thyroid gland. In July, Massachusetts capped the amount of perchlorate allowed in drinking water at two parts per billion. California, on the other hand, is heading toward adopting a standard of six parts per billion. California officials based their proposal on a study authored by the late Dr. Monte Greer, who reported that healthy adults could safely be exposed to perchlorate at concentrations of about 200 parts per billion. The Greer study, however, was limited in scope. It exposed a relatively small number of healthy adults -- 37 -- to perchlorate for just 14 days. Renee Sharp, an analyst at the Environmental Working Group, a nonprofit environmental research organization, said California should have considered how perchlorate can affect sensitive populations, such as children and people with thyroid conditions. In addition, while California officials assumed that 60 percent of the perchlorate a person ingests comes from drinking water, Massachusetts officials put that number at 20 percent, saying people consume more perchlorate from food. The nationwide CDC study found that even low levels of perchlorate can affect thyroid hormone levels. The study found that women with low urinary iodine levels or low levels of iodine in their diet are particularly vulnerable. California's state Office of Environmental Health Hazard Assessment (OEHHA) is now analyzing the CDC's data. The California Department of Health Services is not legally permitted to set a lower standard than OEHHA recommends. If the California standard were set at two parts per billion, the costs of treating water would be "astronomical," said Eric Fraser, Colton's director of water and wastewater.

Article Summary: In a controversial trading plan, South Carolina and other states plan to dish out special mercury emissions credits to power companies. Each credit will have its own serial number, just like a dollar bill, and each credit will represent an ounce of mercury pumped into the air. In South Carolina, these credits could be worth $40 million a year, maybe more. Supporters, including the state's power companies, say these trading programs harness free-market forces to reduce pollution. A successful plan for sulfur dioxide helped lower emissions that cause acid rain, and trading programs are being developed to curb carbon dioxide, a gas that many believe causes global warming. But critics say mercury is different -- the potent neurotoxin that can cause birth defects and learning disabilities tends to fall near emitting plants rather than drift hundreds of miles away. The result: Power companies can get away with polluting a community simply by buying their way out of it. Some states aren't allowing their utilities to trade credits.

Paint manufacturers should pay to clean up the thousands of Cincinnati properties with peeling paint filled with toxic lead particles, city officials say. The city filed a lawsuit this week against nine paint manufacturers -- including Cleveland-based Sherwin Williams -- asking that the companies be required to clean up all lead hazards in properties in the city, pay for a public awareness campaign about lead's dangers and repay the city for years of testing and investigating lead hazards. Lead can cause brain damage and stunt growth when ingested. Children younger than 6 are most susceptible because they're still growing and are likely to touch flakes of lead paint and then put their hands in their mouths.
Article Summary: The lawsuit makes four claims: public nuisance, alleging the paint manufacturers created an unreasonable risk to the health and safety of the public; concert of action, alleging the companies conspired to sell paint they knew was hazardous; unjust enrichment, alleging the companies profited to the detriment of the public; and indemnity, alleging the city has paid to clean up their hazardous product. The lawsuit says the industry knew lead was toxic as early as 1900 but continued to add the metal to paint and even promoted the product as having health benefits. Since 2002, more than 570 young Cincinnati children have been poisoned by lead.
Canton filed a similar suit in Stark County Common Pleas Court on Thursday, following Columbus, East Cleveland, Lancaster and Toledo. Earlier this year, a Rhode Island jury found Sherwin-Williams, NL Industries and Millennium Holdings liable for creating a public nuisance by manufacturing and selling a toxic product. Sherwin-Williams filed a lawsuit in U.S. District Court in Columbus last fall against several cities, including Cincinnati, claiming the plaintiffs conspired with lawyers who want to fleece the company. The company argues that property owners, not the manufacturer, should be held liable for lead hazards. The suit comes a week after the legislature moved to curb product liability lawsuits, capping non-economic damages for lawsuits brought under the Consumer Sales Practices Act at $5,000 and extending protection to manufacturers of lead-based paint.

Although 1 in 4 Americans lives within four miles of a designated toxic-waste site, the federal program to clean up the sites has slowed. Now, key Democrats in Congress are looking to push the program, known as Superfund, back into the spotlight. They're looking not only at its funding levels but also its funding sources. A central issue: whether to restore "polluter pay" taxes on industry to help fund cleanups.
Article Summary: Sen. Barbara Boxer, incoming chairwoman of the environment and public works committee, says she's making Superfund, along with global warming, focal points of her environmental agenda. She has tapped Sen. Hillary Rodham Clinton (D) of New York to chair the Superfund subcommittee. Started in the 1970s, Superfund has seen a decline in funding and completed projects in recent years -- between 1993 and 2005, funding fell 32 percent, from $1.8 billion to $1.2 billion in inflation-adjusted dollars. During the same period, the number of cleanup sites earning "construction complete" status fell by more than half -- from 88 to 40 -- the lowest level in more than a decade. Officials at the Environmental Protection Agency (EPA), which administers the program, deny funding is an issue. Susan Bodine, assistant administrator of the EPA's office of solid waste and emergency response said early completions were the easier sites to clean up. Sites being addressed now are complex, but the EPA is still making progress. Outside observers disagree. Velma Smith, a policy analyst at the National Environmental Trust in Washington, said: "People in the agency are telling me they're giving up on assessing new sites. They may know a problem exists, but they can't get the money to even go out and assess it." The EPA once had a "trust fund" from taxes on the production of toxic chemicals by chemical and oil companies, but authorization for the tax lapsed in 1995. The fund shrank steadily from nearly $4 billion to zero by 2002, despite President Clinton's attempts to get Congress to restore it. President Bush has not asked to renew it. Funding of Superfund programs has shifted to taxpayers. Some Democrats, including Senator Boxer, want to reinstate "polluter pays" taxes. Critics of this approach argue that the tax isn't fair -- companies who don't pollute are taxed, while some polluters don't pay because they're no longer around. Current and former EPA officials don't agree as to whether there's enough money for projects, and some sites declared "clean" still cause controversy.

Article Summary: Even as some states go on a building binge of coal-fired power plants, Washington is considering hefty restrictions that would do the opposite, essentially allowing just one new coal plant to be built. It's part of an emerging schism over coal as a future source of energy, pitting those who see it as reliable and cheap against those who consider it the dirtiest way to make electricity. Washington voters in November endorsed a shift toward cleaner energy. They approved an initiative requiring major utilities to get 15 percent of electricity from renewable sources like wind by 2020. The latest attempts to limit mercury, a potent poison that can hurt development of children's brains, began with a federal rule issued in 2005 that set a 2018 deadline for cutting emissions. Washington is one of at least 15 states that is drafting an even tougher standard. The state also would block coal plants in Washington from participating in a federal "cap-and-trade" program that lets some plants keep puffing out more mercury. This has pitted the state Department of Ecology against the Energy Facility Site Evaluation Council, which oversees permits for new power plants. Ecology is concerned about mercury, while the Energy Facility council sees unacceptable limits to options in the search for new electricity. Projections of electricity needs for the Northwest leave many wondering where it will come from. If the state pursues the tighter limits on mercury, only one more coal-fired plant could be built.

A study by Columbia University scientists has established a link between learning disorders in children and a pesticide that has been used extensively on sweet corn, one of Palm Beach County's major crops. But local and state agricultural officials say the insecticide, chlorpyrifos, does not pose a threat to consumers because it does not leave dangerous levels of residue on the corn. The principal danger may be to families living and working around where the corn is grown who could be affected when the insecticide is applied or the corn picked.
Article Summary: The chemical, marketed as Lorsban, can be sprayed from the air or the ground or applied in granular form. A recent study in Washington state near apple orchards where chlorpyrifos was used found unsafe levels of the chemical in the air in yards near the orchards, according to the Pesticide Action Network, a nonprofit group that collaborated in the study. Sale of chlorpyrifos for residential pesticide use was banned by the federal Environmental Protection Agency as of Dec. 31, 2001, except for childproof containers such as roach traps. The ban followed tests that showed adverse effects on lab animals and other tests that found traces of the chemical in children's blood samples. The insecticide also has been outlawed for use on certain fruits and vegetables, including tomatoes. In fields of sweet corn, it is used to kill worms that attack the crop. The study, published this month in Pediatrics, says that unsafe levels of the chemical cause delays in learning rates and obstruct physical coordination in some children up to age 3. The scientists said children exposed to the pesticide, prenatally or in their first years, also are more likely to incur behavioral problems, specifically attention deficit hyperactivity disorder.

In private conversations across the country this holiday break, pediatricians are buttonholing their congressmen and making a heartfelt plea: Save the National Children's Study. This is the latest attempt to rescue the most important study of children's health and the environment in the United States.
Article Summary: The project, planned since 2000, has enormous scope: Researchers are set to track 100,000 children from birth to age 21, collecting genetic material and blood samples and recording kids' exposure to everything from pesticides to chemicals and air pollution. Enrollment activities were scheduled to begin in 2007, but President Bush's proposed budget called for terminating the $2.7 billion study instead of allocating the $69 million requested for fiscal 2007. The House and Senate appropriations committees responded by affirming strong support, but neither committee set aside new funding for the study. Now a push is on to convince the new, Democrat-controlled Congress that the study needs to go forward and that new funding should be allocated. With chronic conditions such as asthma, autism, diabetes and obesity on the rise in youngsters and definitive scientific explanations lacking, this study could yield enormous financial benefits -- as much as $6 billion in health-care cost savings a year, according to some estimates.

Are pesticides pollutants? That's the question at the heart of a flurry of lawsuits filed against the Environmental Protection Agency this month. The EPA is being sued both by the pesticide industry and environmental activists over a new rule it will adopt in January governing pesticide use in or near water. As of Monday, lawsuits had been filed in 11 of the nation's 13 circuit courts, including the 9th Circuit, which serves Oregon.
Article Summary: This dispute first erupted in Oregon in 2001 when activists filed suit against an irrigation district because of dead fish in a nearby creek that had been poisoned by an herbicide put in the water to control weeds in the irrigation ditches. Environmentalists have argued that pesticides applied directly to water should be subject to Clean Water Act regulations. The 9th Circuit Court concluded that even though the irrigation district followed the label directions of the pesticide, it was discharging a pollutant into a waterway, and therefore needed a special permit. The decision sent tremors through the pesticide realm, from manufacturers to users. Obtaining the Clean Water permits would be an expensive bureaucratic burden on organizations that already comply with EPA pesticide regulations, said Chris West, spokesman for the American Forest Resource Council. More lawsuits followed and the EPA began crafting a rule that would more clearly spell out their requirements for pesticide use. Published in the Federal Register in November and due to take effect in January, it ignores the 9th Circuit Court decision. It says that as long as pesticides are used according to manufacturer instructions they may be applied directly to water, over water or near water by aerial spraying. A decade-long survey of the nation's rivers by the U.S. Geological Survey found pesticides or their components in 90 percent of the 4,380 samples taken from 186 streams and rivers. While the levels rarely exceeded those known to harm people, the concentrations frequently surpassed amounts known to harm fish or fish-eating wildlife. In Washington, requiring users who put the chemical directly into water to have permits already has had an impact: Those who have a permit must monitor the water to make sure their discharges don't exceed concentration levels set by the permit.

Statistics Canada will test the blood and urine of 5,000 Canadians, ages 6 to 79, so the government can for the first time chart the chemicals that pollute our bodies. The federal government's first large-scale survey mirrors similar efforts in the United States that have found that virtually the entire population carries a complex burden of pollutants in their tissues. The blood and urine will be subjected to a battery of expensive tests that will check for 70 metals and chemicals, including DDT, the once widely used insecticide that has been banned for decades. DDT is still found throughout the environment because it degrades so slowly.
Article Summary: Many of the substances to be monitored have only recently emerged as potential health threats and are a worry because the chemicals appear to be leaking out of common consumer products and getting into people. These chemicals include bisphenol A, phthalates, brominated flame retardants, weed killers and cotinine, which indicates exposure to cigarette smoke. It is unknown whether current exposures to these substances or their interactions in people's bodies is harmful, although animal experimentation has found that during early life and fetal development even trace exposures to some of the substances can skew development in ways that increase the chances of cancers and other health problems later in life. Federal officials say the survey will close a huge gap in Canadian public-health measurements, the lack of comprehensive information on the amount of pollutants that people are carrying in their bodies. The U.S. has been issuing results of large-scale testing for contaminants, a process known as biomonitoring, since 2001. When the sampling is completed some time in 2009, researchers will have a national chemical snapshot for how contaminated Canadians were at this point, which will become the baseline for subsequent tests. This information will enable monitoring results of any regulatory efforts to ban these substances or limit exposure.

Article Summary: There's a battle being waged over the environmental and health impacts of synthetic chemicals used in beauty products and toiletries. Scientists, health lobbyists and environmental campaigners argue that the cosmetics industry is among the world's least regulated, using thousands of chemicals that have not been subject to adequate assessment. In the United States, studies by the Environment Protection Authority have linked endocrine disrupters used in toiletries and household cleaners to hormone disruption in wildlife, possibly caused by water pollution from urban wastewater. Phthalates are synthetic chemicals linked to decreased fertility and reproductive defects and now one of the most abundant industrial pollutants in the environment. A recent report by global lobby group Health Care Without Harm and the Swedish Society for Nature Conservation tested 34 leading-brand cosmetics and found phthalates in 80 per cent of products, with more than 50 per cent containing more than one type of phthalate. According to the report, "none of the products listed phthalates as an ingredient on the label." The United States Environmental Working Group's Skin Deep personal product care safety guide reports on the safety of cosmetics. On its website Skin Deep offers comprehensive assessments of almost 15,000 skin and hair care products, cosmetics, sunscreens and toothpastes, providing safety ratings based on toxicity tests and regulatory databases. The organization claims more than one-third of all personal care products contain at least one ingredient linked to cancer; 57 per cent of all products contain "penetration enhancer" chemicals that can drive other ingredients faster and deeper into the skin to the blood vessels below; and 79 per cent of all products contain ingredients that may contain harmful impurities. The United States Geological Survey recently released a study revealing triclosan, a chemical that mimics the thyroid hormone and is commonly added to soaps, toothpaste, deodorant and dog shampoos, is present in 60 percent of the nation's rivers and lakes. It's bioaccumulative, building up in fatty tissue and has been found in human breast milk and fish. Hundreds of ethical cosmetics companies throughout the world have signed the compact for safe health and beauty products from the global Campaign for Safe Cosmetics, pledging not to use chemicals known or strongly suspected of causing cancer, mutation or birth defects in their products and to develop substitution plans replacing environmentally hazardous materials with safer alternatives.

Women who take high doses of fish oils during pregnancy could dramatically boost their children's coordination, say researchers. A new study reveals the benefits of using so-called "clever capsules" to help develop the full potential of babies while still in the womb. It found a significant advance in hand-eye coordination among toddlers whose mothers took fish oil supplements during the second half of pregnancy compared with those who did not. There was also improvement in brainpower and vocabulary among children exposed to fish oil supplements in the womb, says the study published on Thursday online in the medical journal Archives of Disease in Childhood.
Article Summary: Fish oil is high in Omega 3 fatty acids, which play an important part in the development of the central nervous system. The last three months of pregnancy are thought to be a key time for intake of fish oil because there is a growth spurt in the human brain during this time, which carries on into the first few months of a baby's life. The study looked at 98 pregnant women, who were either given 4g of fish oil supplements or 4g of olive oil supplements daily from 20 weeks of pregnancy to the birth of their babies. When the children reached the age of two and a half, they were given various tests measuring growth and development. Children whose mothers had taken fish oil supplements scored significantly higher in hand-eye coordination than those whose mothers had taken olive oil supplements. Fish oil children also scored more highly on comprehension, phrase length and vocabulary. Concern over the mercury content in certain types of fish has made high quality fish oil supplements increasingly popular.
Fish oils can also help pregnant women in a number of ways, including reducing high blood pressure and easing postnatal depression. There is international evidence of the benefits of omega 3 for people with heart conditions, and evidence is mounting in studies on children's learning and behavior.

In a bid to trim the regulatory burden on small businesses, the Environmental Protection Agency is set to relax the rules on what toxic chemicals they have to report. But in a twist, the EPA's newly revised Toxics Release Inventory rule will also make it possible for hundreds of large corporations to avoid reporting specific amounts of toxic chemicals they release into the air, land, or water, environmentalists warn. The rule change has cheered small-business groups, generated widespread public opposition, and caught the eye of some Democratic congressmen, who will take control of Congress next month. It takes effect immediately.
Article Summary: Companies that release into the environment relatively small amounts of toxic materials -- no more than 2,000 pounds of a given chemical, such as toluene -- can complete a simpler form that omits reporting the amount of toxic chemicals. Another class of even more dangerous toxins can qualify for similar streamlined reporting if the waste was less than 500 pounds, entirely recycled, and not released at all. The rules apply only if the company created less than 5,000 pounds of a chemical in a year. Of 24,000 facilities currently reporting TRI data, about one-third could be eligible to fill out a short form that simply lists the chemical.
This change will make it more difficult for neighborhoods, researchers or others to find out how much of a toxic chemical a nearby factory is emitting. Federal officials contend that such limits spur business to reduce their toxic waste and will save $6 million annually in unnecessary paperwork. Business groups applaud the change, but critics say the move seems to be an effort to weaken a reporting law that has empowered community activists with details about some 650 industrial chemicals that the TRI tracks. Critics also argue that, although this is being touted as a boon to small business, big companies will be among the largest beneficiaries. It also leaves room for emissions to rise without data being made public.

Article Summary: DDT is a persistent organochlorine compound that has been used worldwide as an insecticide. The authors evaluated the association of cord serum levels of DDT and its metabolite, 2,2-bis(p-chlorophenyl)-1,1-dichloroethylene (DDE), with neurodevelopment at age 4 years. Two birth cohorts in Ribera d'Ebre and Menorca (Spain) were recruited between 1997 and 1999 (n = 475). Infants were assessed at age 4 years by using the McCarthy Scales of Children's Abilities. Organochlorine compounds were measured in cord serum. Children's diet and parental sociodemographic information was obtained through questionnaire. Results showed that DDT cord serum concentration at birth was inversely associated with verbal, memory, quantitative, and perceptual-performance skills at age 4 years. Children whose DDT concentrations in cord serum were >0.20 ng/ml had mean decreases of 7.86 (standard error, 3.21) points in the verbal scale and 10.86 (standard error, 4.33) points in the memory scale when compared with children whose concentrations were <0.05 ng/ml. These associations were stronger among girls. Prenatal exposure to background, low-level concentrations of DDT was associated with a decrease in preschoolers' cognitive skills. These results should be considered when evaluating the risk and benefits of spraying DDT during antimalaria and other disease-vector campaigns.
