Cancer risks linked to common pollutant "Growing scientific evidence suggests the most widespread industrial contaminant in drinking water - a solvent used in adhesives, paint and spot removers - can cause cancer in people. . A committee of academy experts said 'a large body of epidemiologic data is available' on TCE showing the chemical is a possible cause of kidney cancer, reproductive and developmental damage, impaired neurological function and autoimmune disease."
Chemical Exposure Creating a "Silent Pandemic" of Neurodevelopmental Disorders? "An online review article published November 8 in the Lancet says environmental exposure to toxic chemicals in utero and in the early stages of life may be creating a "silent pandemic" of neurodevelopmental disorders. … The article cites 5 industrial chemicals, including lead, methylmercury, and polychlorinated biphenyls (PCBs), solvents, and pesticides, that are recognized causes of neurodevelopmental disorders. Exposure to these chemicals during early fetal development can cause brain injury at doses much lower than those affecting adults. Recognition of these risks has given rise to evidence-based programs of prevention, such as the elimination of lead additives in gasoline and house paint. While such initiatives have been effective, most have been initiated only after substantial delays, they point out."

Association of Blood Lead and Tibia Lead with Blood Pressure and Hypertension in a Community Sample of Older Adults. (Am J Epidemiol. 2006)
Blood Lead Below 0.48 µmol/L (10 µg/dL) and Mortality Among US Adults (Circulation 2006) "Conclusions--The association between blood lead levels and increased all-cause and cardiovascular mortality was observed at substantially lower blood lead levels than previously reported. Despite the marked decrease in blood lead levels over the past 3 decades, environmental lead exposures remain a significant determinant of cardiovascular mortality in the general population, constituting a major public health problem."
Blood Lead Levels and Death from All Causes, Cardiovascular Disease, and Cancer: Results from the NHANES III Mortality Study. (Environ Health Perspect. 2006) "Conclusion In a nationally representative sample of the U.S. population, blood lead levels as low as 5-9 mug/dL were associated with an increased risk of death from all causes, cardiovascular disease, and cancer."

Complementary and alternative medicine use among midlife women for reasons including menopause in the United States: 2002. (Menopause. 2006) "RESULTS:: Forty-five percent of women 45 to 57 years of age had used some form of CAM within the last 12 months. Approximately 25% used biologics (e.g., herbs) or mind-body (e.g., biofeedback) modalities, whereas only 15% used body work (massage and chiropractic medicine). Use did not vary by age, but white race, higher education, and residence in the West were associated with increased use. Only 45% of CAM users mentioned its use to a medical provider. The most cited reason for using CAM involved treatment of pain, with only 3% mentioning menopause. However, the odds for use of CAM were almost twice as high for women with menopausal symptoms in the past year compared with women with no symptoms …"
Contaminants, diet, plasma fatty acids and smoking in Greenland 1999-2005. (Sci Total Environ. 2006) "CONCLUSION: The main predictors of high contaminant levels in Greenland were age, district, male gender, smoking and high plasma n-3/n-6 ratio as a marker of high dietary intake of local marine mammals."

Deaths associated with hypocalcemia from chelation therapy--Texas, Pennsylvania, and Oregon, 2003-2005. (MMWR Morb Mortal Wkly Rep. 2006) "This report describes three deaths associated with chelation-therapy--related hypocalcemia that resulted in cardiac arrest. Several drugs are used in the treatment of lead poisoning, including edetate disodium calcium (CaEDTA), dimercaperol (British anti-Lewisite), D-penicillamine, and meso-2,3-dimercaptosuccinic acid (succimer).Health-care providers who are unfamiliar with chelating agents and are considering this treatment for lead poisoning should consult an expert in the chemotherapy of lead poisoning. Hospital pharmacies should evaluate whether continued stocking of Na2EDTA is necessary, given the established risk for hypocalcemia, the availability of less toxic alternatives, and an ongoing safety review by the Food and Drug Administration (FDA). Health-care providers and pharmacists should ensure that Na2EDTA is not administered to children during chelation therapy."

Findings of and treatment for high levels of mercury and lead toxicity in ground zero rescue and recovery workers and lower Manhattan residents. (Explore (NY). 2006) "Of those tested for heavy metal toxicity, using a challenge urine test, 85% had excessively high levels of lead and mercury. Chelation treatment using dimercaptuosuccinic acid (DMSA), a Food and Drug Administration (FDA)-approved sulfur compound, was the primary treatment prescribed. After three to four months of treatment, the first cohort of 100 individuals reported significant (greater than 60%) improvement in all symptoms."
Inorganic arsenic in cooked rice and vegetables from Bangladeshi households. (Sci Total Environ. 2006) "Given the arsenic levels measured in food and water and consumption of these items, cooked rice and vegetables are a substantial exposure pathway for inorganic arsenic. Intervention strategies must consider all sources of dietary arsenic intake."

Mercury content in commercial pelagic fish and its risk assessment in the Western Indian Ocean. (Sci Total Environ. 2006) "The muscular Hg levels presented here suggest that consumers of fish originating from theWestern Indian Ocean should limit themselves to one Swordfish based meal per week, or one fish meal a day if they choose to eat tuna or Common Dolphinfish."

Pesticides and their Metabolites in the Homes and Urine of Farmworker Children Living in the Salinas Valley, CA. (J Expo Sci Environ Epidemiol. 2006) "Pesticides were detected more frequently in house dust, surface wipes, and clothing than other media, with chlorpyrifos, diazinon, chlorthal-dimethyl, and cis- and trans-permethrin detected in 90% to 100% of samples. . Several OP pesticides, as well as 4,4'-DDE, atrazine, and dieldrin were detected in the food samples."
Reduced Intellectual Development in Children with Prenatal Lead Exposure (Environ Health Perspect 2006) "Conclusions: Lead exposure around 28 weeks gestation is a critical period for later child intellectual development, with lasting and possibly permanent effects. There was no evidence of a threshold ; the strongest lead effects on IQ occurred within the first few micrograms of BPb."
