PRENATAL AND POSTNATAL EXPOSURE TO POLYCHLORINATED BIPHENYLS LINKED TO POOR INFANT COGNITIVE DEVELOPMENT (pp 1568, 1602)
A study in this week's issue of THE LANCET suggests that both prenatal and postnatal exposure to polychlorinated biphenyls-from maternal blood and breastmilk, respectively-can hinder early childhood cognitive development. The study also concludes that a stimulating home environment can counteract... view more (2001-11-07)

New study suggests that women eating PCB contaminated fish are less likely to give birth to boys
New research published in the open access journal, Environmental Health: a Global Access Science Source suggests that women exposed to polychlorinated biphenyls are less likely to give birth to boys. The results come from a study of mothers and fathers around the Great Lakes region of the United... view more (2003-04-30)

Teenage Boys Exposed To Environmental Pollutants Less Likely To Produce Male Children (p143)
A research letter in this week's issue of THE LANCET provides further evidence that adolescent boys exposed to organic pollutants are less likely to father a male child in adulthood. Investigators from the National Cheng Kung University Medical College, Taiwan, and the London School of Hygiene and... view more (2002-07-10)

Persistent Man-made Chemical Pollutants Found in Deep-sea Octopods and Squids
New evidence that chemical contaminants are finding their way into the deep-sea food web has been found in deep-sea squids and octopods, including the strange-looking "vampire squid". These species are food for deep-diving toothed whales and other predators.   view more (2008-06-10)

Precision biochemistry tracks DNA damage in fish
Like coal-mine canaries, fish DNA can serve as a measure of the biological impact of water and sediment pollution-or pollution clean-up.   view more (2006-05-15)

BIOMARKERS IN ADOLESCENTS COULD PROVIDE MEASUREMENT FOR ENVIRONMENTAL POLLUTION (p 1660)
Biological markers in adolescents could be a reliable measure of exposure to environmental pollutants, according to a study in this week's issue of THE LANCET which highlights how increased exposure among adolescents slows sexual development. Human exposure to chemicals is normally monitored by... view more (2001-05-23)

New research finds some wood floor finishes are a likely source of PCB exposure
A case study to be published in the online open access journal Environmental Health suggests that old wood floor finishes in some homes may be an overlooked source of exposure to the now banned environmental pollutants polychlorinated biphenyls (PCBs).   view more (2008-01-17)

Exposure to PCBs May Reduce the Effectiveness of Vaccines in Children
New epidemiological evidence suggests that exposure to environmental pollutants may have an adverse impact on immune responses to childhood vaccinations.   view more (2006-08-23)

Standardized house dust aids health researchers
Chemists at the National Institute of Standards and Technology (NIST) have created a standardized form of common house dust to support environmental scientists studying our everyday exposure to a catalog of potentially hazardous chemicals.   view more (2007-02-02)

Environmental pollutant has sex-skewing effect
Women exposed to high levels of PCBs (polychlorinated biphenyls - a group of banned environmental pollutants) are less likely to give birth to male children.   view more (2008-07-16)

Bacterium could treat PCBs without the need for dredging
Researchers at Rensselaer Polytechnic Institute have discovered a tiny bacterium that could one day transform the way we remove polychlorinated biphenyls (PCBs) from our environment. The organism could be the key to developing methods that help detoxify commercial PCB compounds on site —... view more (2007-03-08)

Contaminants linked to sturgeon decline in Columbia river
White sturgeon populations in the Columbia River may be declining due to the presence of elevated amounts of foreign chemicals including DDT and polychlorinated biphenyls in their bodies.   view more (2006-04-07)

Wildlife researchers identify impacts of contamination in amphibians
Bill Hopkins, fisheries and wildlife associate professor in Virginia Tech's College of Natural Resources, and colleagues doing research at the Savannah River Ecology Laboratory and in the field, have demonstrated that amphibians are exposed to contaminants through maternal transfer, as has been... view more (2006-02-22)

EU research suggests that PCBs damage sperm - but finds no dramatic effect on male fertility
Research by an EU-supported international team of scientists has shown that polychlorinated biphenyls (PCBs)[1]-synthetic organic chemicals found widely in the environment and absorbed in the diet - may damage sperm.   view more (2005-10-13)

Sediment dredging has fallen short of achieving cleanup goals at many contaminated sites
At many projects to dredge contaminated sediments from U.S. rivers and other bodies of water, it has not been demonstrated that dredging has reduced the long-term risks the sediments pose to people and wildlife.   view more (2007-06-06)

Herons persist in Chicago wetlands despite exposure to banned chemicals
Herons nesting in the wetlands of southeast Chicago are still being exposed to chemicals banned in the U.S. in the 1970s, a research team reports. The chemicals do not appear to be affecting the birds' reproductive success, however.    view more (2008-01-17)

Chemical Compounds Present in Diet Increase Risk of Colon Cancer
A team of researchers at the Universitat Autònoma de Barcelona, The Catalan Institute of Oncology and the Higher Council for Scientific Research (CSIC) have published a study indicating that exposure to organochlorine compounds, which we ingest in our diets, increases the risk of suffering... view more (2005-04-01)

UNH Researchers Test Sediment-Scrubbing Technology In Cocheco River
In a mud flat at the edge of the Cocheco River, just outside downtown Dover, scientists from the University of New Hampshire's Contaminated Sediments Center are testing an innovative way to treat polluted sediment in coastal waterways.   view more (2008-06-18)

Albatross study shows regional differences in ocean contamination
As long-lived predators at the top of the marine food chain, albatrosses accumulate toxic contaminants such as PCBs, DDT, and mercury in their bodies. A new study has found dramatic differences in contaminant levels between two closely related albatross species that forage in different areas of the... view more (2006-04-05)

Maternal exposure to persistent organic pollutants linked to urologic conditions in boys
Higher incidences of congenital anomalies, including cryptorchidism (undescended testicles) and hypospadias, were found in boys whose mothers had higher serum levels of certain organochlorine compounds, researchers say.   view more (2008-05-15)

Chemicals used as fire retardants could be harmful, UC-Riverside researchers say
Polybrominated diphenyl ethers (PBDEs), chemicals used as fire retardants, can be found in numerous items in the home, such as the television, computer, toaster and the sofa.
