Chemical Concentrations Do Not Decrease During Lactation

15.07.2009
A study published 15 June 2009 ahead of print in the peer-reviewed journal Environmental Health Perspectives (EHP) suggests that lipid-adjusted concentrations of polybrominated diphenyl ethers, polychlorinated biphenyls, polychlorinated dibenzo-p-dioxins and furans and organochlorine pesticides in women’s blood serum and milk do not decrease during lactation as previously thought. This new insight should improve researchers’ ability to assess infant exposures to environmental chemicals via breastfeeding.

This new finding also challenges the idea that early milk should be pumped and discarded as a means of reducing infant exposure to persistent organic pollutants, which can accumulate in a mother’s fat stores over her lifetime and be mobilized during lactation.

First author Judy S. LaKind and colleagues found that partitioning of chemicals between serum and human milk was complex and related to chemical class. The authors suggest that the milk/serum ratios determined by this research be used to evaluate infant exposure if only serum data are available. They also recommend that additional studies that include a larger cohort be conducted to confirm these results.

“This is the first study to provide data based on simultaneous sampling of breast milk and blood at separate times during lactation,” wrote the authors.

Other authors of the paper included Cheston M. Berlin, Jr., Andreas Sjödin, Wayman Turner, Richard Y. Wang, Larry L. Needham, Ian M. Paul, Jennifer L. Stokes, Daniel Q. Naiman and Donald G. Patterson, Jr. Support for this research was provided in part by the Research Foundation for Health and Environmental Effects, Arlington, VA.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
