Toenails part of study on link between N.S. cancer rates and arsenic in water.
Researchers are trying to figure out why Nova Scotians have the highest overall incidence of cancer in the country - including among the highest rates of bladder and kidney cancer. A three-year study will examine the potential link between cancer and low to moderate amounts of arsenic in the body and drinking water. Canadian Press. 6 May 2009.
Consortium rejects FDA claim of BPA's safety.
An international consortium of industry, academic and government scientists has rejected as incomplete and unreliable the U.S. Food and Drug Administration's case that a chemical found in food containers and other household products is safe. Milwaukee Journal Sentinel, Wisconsin. 12 April 2009.
When fed to fish, a common flame retardant affected thyroid-related gene actions and hormone levels that could alter metabolism, although the changes differed between the high and low doses tested.
Determining how these changes translate into health consequences for humans becomes a critical point since minnows and humans have similar thyroid hormone systems. In both, the thyroid gland, pituitary gland and hypothalamus work together to control many body functions, mainly metabolism. 2 February 2009. More...
Study can't pinpoint extent of lead exposure.
Scientists say they might never know how many children were harmed when lead levels in the District's water spiked early this decade. The number could be as few as 700 or as many as tens of thousands. Washington Post. 31 January 2009.
Potomac River tap water has small levels of contaminants.
Tap water in the District and parts of Northern Virginia contains small amounts of herbicides, gasoline additives and industrial solvents with concentrations so small that there is probably no risk to consumers, according to a new federal study. Washington Post. 6 December 2008.
Chemical traces left in treated water, study finds.
Low levels of manufactured chemicals remain in drinking water supplies even after the water is treated for effluent and other pollutants, according to a U.S. Geological Survey study released Friday. Kansas City Star, Missouri. 6 December 2008.
Advisers: FDA decision on safety of BPA 'flawed.'
A Food and Drug Administration advisory board voted today to say that the agency ignored critical evidence suggesting that a controversial plastic chemical bisphenol A, or BPA, could harm children. USA Today. 1 November 2008.
Mice exposed to low levels of soy proteins before and shortly after birth were obese as adults and had reproductive changes that differed between the sexes.
The findings provide additional evidence that hormonally active compounds can act at low exposure levels and produce effects different from those caused by high exposures. 24 September 2008. More...
For the first time, scientists have demonstrated experimentally a strong effect of low doses of bisphenol A on monkeys, raising new concerns about possible effects on people.
After a month of continuous low-dose exposure, the ability of the monkeys brains to form key connections was eliminated. The study suggests that BPA exposure may be related to human brain disorders and diseases, such as Alzheimer's disease, schizophrenia and mood disorders. 10 September 2008. More...
Soil lead threat in big cities.
While lead has been phased out of U.S. gasoline, paint and other products, lead levels in dirt -- maybe even the soil in your yard or the local playground -- are still a public health hazard, warns an Indianapolis researcher. Springfield News-Leader, Missouri. 8 September 2008.
Plastic bottles, cans are hazardous for human health.
Bisphenol A, the primary chemical used to produce hard plastics like bottles, can be a potential risk factor for metabolic syndrome and its consequences, according to a new research from the University of Cincinnati. Asian News International, South Asia. 7 September 2008.
In human fat tissues, bisphenol A suppresses levels of a key hormone, adiponectin, that protects people from heart attacks and Type II diabetes.
These results implicate BPA as a potential cause of metabolic syndrome, one of the most serious and costly public health problems in the US. 18 August 2008. More...
Trade unions call for REACH amendment to cover nanomaterials.
The confederation of unions is calling on the Commission to amend the bloc's chemicals legislation (REACH) to cover nanomaterials manufactured or imported below the threshold of one tonne per year. Euractiv, Belgium. 1 July 2008.
Your shower curtain might be bad for you.
As part of an ongoing campaign against polyvinyl chloride, a Virginia-based environmental advocacy group today called on manufacturers and retailers to phase out its use in shower curtains. US News & World Report. 13 June 2008.
Safety of C8 substitutes questioned.
Government and industry may be hiding C8 substitute products' effects on human health. Charleston Gazette, West Virginia. 10 June 2008.
Low radon exposure may be harmless.
Radon levels typically found in homes in the US do not raise the risk of lung cancer, according to findings from a decade-long case-control study. In fact, the dose-response effect of radon exposure may be hormetic, i.e., protective at low doses but harmful at higher levels, the researchers suggest. Reuters Health. 18 April 2008.
Time to update environmental regulations.
Should public health standards for endocrine-disrupting compounds be based upon sixteenth century dogma or modern endocrinology? San Francisco Medicine. Opinion, 7 April 2008.
Chemical reaction.
For years, athletes and hikers have toted their water in colourful, durable bisphenol A bottles. Baby bottles, too, have been made of BPA. Now, all of a sudden, it is in the headlines. Ottawa Citizen, Ontario. 10 February 2008.
Minute quantities of a bacterial protein inserted in corn provoke immune reactions in mice.
The protein is added to increase the effectiveness of plant-based transgenic vaccines. The results indicate that special care will be needed with transgenic corn to reduce exposure to workers and the public if this protein is used commercially in corn or other food crops, to avoid unwanted immune responses in people and decreased effectiveness of oral vaccines that use the protein. 8 November 2007.

Exposure to a mixture of phthalates causes reproductive harm in an additive manner.
Rats exposed prenatally to a combination of DEHP and DBP had decreased testosterone levels and decreased expression of genes important for gonadal development. This research has important implications for humans who are continually exposed to low doses of a mixture of phthalates. Toxicological Sciences 8 July 2007. More...
Judge orders OSHA to release toxic info.
A federal judge has ordered the Labor Department to share with the public the results of years of toxic substance sampling in American workplaces. Associated Press. 3 July 2007.
Prenatal exposure to a mixture of anti-androgenic chemicals produces changes in the structure of and genes expressed in male reproductive organs.
Rats exposed to a mixture of vinclozolin, flutamide and procymidone had abnormal development of the prostate, seminal vesicles and epididymis. Exposure to low doses of each individual chemical did not cause these effects but exposure to a mixture of low doses did, indicating an additive effect. This research has important implications for similar conditions in humans, who are routinely exposed to mixtures of low doses of chemicals. Toxicological Sciences 1 July 2007. More...
The first study to examine the connection between human exposure to phthalates and changes in thyroid hormone levels reports that men with higher levels of the phthalate breakdown product MEHP in their urine had lower levels of two major thyroid hormones, T4 and T3 in their blood.
Changes in thyroid hormone levels can affect growth, development and metabolism and cause a number of human diseases. More research is needed to establish whether MEHP is causing the thyroid declines. 12 June 2007. More...
