Alternative chemicals ease safety concerns about nonstick, repellent coatings

04.02.2010
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 perfluorooctanoic acid (PFOA) can cause developmental problems, liver toxicity, and cancer in animals. Uncertainty exists over their health effects in people.

Nevertheless, chemical companies are working with the U.S. Environmental Protection Agency (EPA) to phase out PFOS and are in the process of phasing out PFOA. The companies are replacing these chemicals with shorter chain fluorochemicals that perform just as well but appear to be safer.

Although these new ingredients are considered sound replacements, they may only be a temporary fix, pending development of a new generation of less toxic substitutes. After being surprised by the unexpected environmental persistence of PFOA and PFOS, EPA is taking extra caution with the replacements to avoid a similar problem in the future.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
