Lead levels in both soil and children declined dramatically after hurricanes twice flooded New Orleans in 2005. The researchers who report the results propose that the flooding altered the soil lead conditions, thereby lowering children's exposure to the neurotoxin.
In almost all of the neighborhoods tested, soil lead levels fell by almost 50 percent to well below federal safety standards. At the same time, children's blood lead levels decreased more than 30 percent. 8 July 2010. More...
A new method for removing fluorines from fluorinated chemicals offers a promising method to detoxify some types of organohalogen pollutants, such as CFCs.
The method could be more broadly applied to other organofluorines, including perfluorinated compounds (PFCs) such as PFOA and PFOS. PFOA is a chemical used in nonstick cookware and PFOS was used in anti-stain fabrics and water resistant coatings. 17 June 2010. More...
A study conducted in Massachusetts suggests that exposure to perchloroethylene through drinking water may be associated with an increased risk for certain congenital anomalies, but the results are not entirely conclusive.
Women whose estimated PCE exposure was higher may have a 50 percent increased risk of birth defects. Women ever exposed to PCE also had a 3-fold increased risk of giving birth to babies with neural tube defects or oral clefts. 28 January 2010. More...
A new study finds that fewer older people are hospitalized due to heart problems associated with air pollution if they live in places that have more homes with central air conditioning.
But, a vicious cycle of energy demand, air conditioning use and air pollution can develop, the researchers explain. More air conditioning use requires more energy. Generating energy leads to air pollution and contributes to global warming, possibly spurring higher use of air conditioning. 4 September 2009. More...
A detailed analysis of all the available studies comparing work-related, parental pesticide exposure and childhood leukemia finds that the mother’s exposure during pregnancy can double her child’s risk of the disease. The father’s exposure before pregnancy does not.
The study emphasizes the significant contribution of prenatal exposure in developing childhood disease and shows a need for more in-depth studies of the effects of prenatal exposures to environmental factors. 17 June 2009. More...
Weather changes due to global climate change could substantially increase people's exposure to many pathogens and toxic agricultural contaminants, predicts a study from the United Kingdom.
The full health implications are uncertain. Managing the risks will require research as well as policy changes. 26 February 2009. More...
A common disinfectant used by public water treatment plants creates a byproduct that is highly toxic to mammalian cells. How much is made depends upon details of how the plants process water.
The amount produced can be reduced significantly by simple changes in the treatment process. Despite this, many plants continue to use methods that create more of the toxic chemical than necessary. 18 November 2008. More...
In a new study, scientists report that ground level mercury levels are increased by more than 30% in environments where the greenhouse gas carbon dioxide is also increased.
The cause is unexpected: Higher CO2 levels change soil chemistry in ways that increase its ability to retain or store mercury. 12 September 2008. More...
Traditional covert influence of industry on occupational and environmental health policies has turned brazenly overt in the last several years.
More than ever before the OEH community is witnessing the perverse influence and increasing control by industry interests. Government has failed to support independent, public health-oriented practitioners and their organizations, instead joining many corporate endeavors to discourage efforts to protect the health of workers and the community. International Journal of Occupational and Environmental Health [PDF]. 2 March 2007. More...
Science Byte: The combination of climate change and widespread contamination by endocrine-disrupting contaminants may be the 'worst-case' for Arctic wildlife.
Climate change is forcing Arctic wildlife to adapt to rapid changes in ecological circumstances. EDCs, how at high levels in many Arctic wildlife, compromise immune, reproductive and neurological systems of animals, and may undermine the ability of wildlife to adapt to increased environmental stress. EHP. 3 November 2005. More...
Experiments with mice show that exposure to bisphenol A within the range that people commonly experience causes insulin resistance.
The results indicate that exposure to low levels of BPA may be involved in 'metabolic syndrome,' including type II diabetes. Human exposure to BPA has become almost universal in the last 2 decades, because of its use in polycarbonate plastic, epoxy linings for food cans, and cavity prevention tools for children. 11 October 2005.

Chemicals used as alternatives to ozone-depleting solvents found to have reproductive toxicity.
2-bromopropane (2-BP) was found to cause mutations and is toxic to sperm and eggs. 1-bromopropane, introduced as an alternative to 2-BP inhibits the release of sperm and has neurological toxicity. This serves as another example of how replacing one halogenated chemical with another often results in another type of toxicity. International Archives of Occupational and Environmental Health 1 March 2005. More...
Endocrine disrupting compounds interfere with nitrogen fixation in legumes.
Scientists from Tulane University report in Nature that several EDCs can interfere with the chemical signaling from plant to bacteria that initiates the symbiotic relationship crucial for nitrogen fixation, an ecological process vital to life on earth. By binding with a bacterial receptor that normally receives the plant signals, these contaminants prevent activation of the bacterial gene that initiates formation of the nodules where nitrogen fixation takes place. 15 September 2001.
