Amid concern about the potential toxic effects of the fluorochemicals used in nonstick cookware, water-repellent clothing, and other consumer products, manufacturers are using new versions of these chemicals that may be safer. That's the topic of the cover story in the current issue of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine. C&EN Senior Editor Stephen K. Ritter cites indications that long-chain compounds like perfluorooctane sulfonate (PFOS) and...

A study by the University of Exeter and the Peninsula Medical School for the first time links thyroid disease with human exposure to perfluorooctanoic acid (PFOA). PFOA is a persistent organic chemical used in industrial and consumer goods including nonstick cookware and stain- and water-resistant coatings for carpets and fabrics. Published in the journal Environmental Health Perspectives, The study revealed that people with higher concentrations of PFOA in their blood have higher rates of...

BETHESDA, Md., March 12 /PRNewswire/ -- The Sapphire Group today released the results of a new study which found that levels of perfluorooctanoic acid (PFOA) found in drinking water supplies are safe for human exposure. PFOA, sometimes referred to as C8, is a substance used in the manufacture of a variety of non-stick and stain resistant protective coatings. Concentrations of PFOA found in drinking water supplies range from less than the detectable limit of 7.5 parts per trillion to 3.5...

Chemicals used in food packaging, pesticides, clothing, upholstery and carpets may be associated with infertility in women, U.S. researchers said. The study, published in Human Reproduction, found that women who had higher levels of perfluorooctanoate and perfluorooctane sulfonate in their blood took longer to become pregnant than women with lower levels. First author Dr. Chunyuan Fei of the University of California, Los Angeles, said that blood samples were taken at the time of the women's...

PARKERSBURG, W. Va., Jan. 27 /PRNewswire/ -- The C8 Science Panel has completed a new study on uric acid and C8 and C8S, based on existing data from the C8 Health Project. While increased uric acid is associated with higher levels of C8 and C8S, the data are not sufficient to show that these chemicals can cause an increase in uric acid. The Science Panel team recently completed a study on the relationship between uric acid and C8 (also known as PFOA) and C8S (also known as PFOS) in the blood...

By Emma Brady Researchers at a Midland university have found that dust found in some of the region's primary school classrooms is contaminated with high levels of pollutants and chemicals which could prove toxic. Birmingham University, which presented its results to the Dioxin 2008 conference on Thursday, found the dust contained concentrations of HBCD, TBBP-A, PFOS, and PFOA. All four chemicals are persistent organic pollutants (POPs) which do not degrade in the environment, instead...

Question: Scotchgard contains perfluorochemicals, which have been in the news. I have Scotchgard on my children's mattresses. Can they safely sleep on these? Answer: It's probably safe to sleep on a mattress that was treated with Scotchgard, said Minnesota Health Department spokesman Doug Schultz. The worry with perfluorochemicals (PFC) is ingestion, not skin contact. Children would have to get it into their mouths. One way that might happen is as Scotchgard breaks down over time and...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
