Diet May Contribute Significantly to Body Burden of Flame Retardants

15.07.2009
A study published online 18 June 2009 ahead of print in the peer-reviewed journal Environmental Health Perspectives (EHP) suggests that diet is an important route of exposure to polybrominated diphenyl ethers (PBDEs). PBDEs are a class of flame retardants that are commonly found in consumer products such as polyurethane foam, electronics and textiles.

PBDEs have been measured in dust, air and both animal- and plant-derived foods. Dust has been thought to be the foremost route of exposure to PBDEs, but the new findings of this study suggest that diet also may play a significant role. Serum levels of PBDE congeners were associated with consumption of fat from poultry and red meat but not with consumption of fish or dairy products.

Although it is not known how flame retardants get into commercial animal products, possibilities include the contamination of animal feed, contamination during processing or packaging and general contamination of the environment. PBDEs accumulate in fat tissue and resist degradation in the environment.

“Our study offers the first large-scale look at the effect of the American diet on PBDE body burdens showing significant associations with poultry and red meat consumption,” wrote the team of authors from the Boston University School of Public Health. “As PBDE-containing products continue to degrade and enter the waste stream in larger amounts, future exposure to PBDEs may begin to shift more heavily from the indoor environment to the outdoor environment and, consequently, the diet.”

PBDEs have been shown to cause adverse endocrine, neurologic and hepatic effects in laboratory animals. Human studies to date suggest PBDEs may affect male development, reproductive hormones and fertility and thyroid hormone homeostasis.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
