University of Exeter researcher, Professor Tamara Galloway, has contributed to one of the most expansive summaries of our knowledge of man-made litter in the world's oceans to date. The new book, Marine Anthropogenic Litter is published by Springer and is set to be available through open access, allowing its content to reach the wider audience that is so necessary to raise awareness of this important challenge.
Plant-based cellulose nanofibres do not pose a short-term health risk, especially short fibres, shows a study conducted in the context of National Research Programme "Opportunities and Risks of Nanomaterials" (NRP 64). But lung cells are less efficient in eliminating longer fibres.
SCIENTISTS are investigating the use of man-made sponge-like materials as a new way of solving important engineering challenges for future generations of nuclear reactors, such as the accumulation of gas, which can lead to structural weakness. Now, a research project at the University of Huddersfield has been awarded major funding to explore the possibilities.
Exposure of a model human colon to metal oxide nanoparticles, at levels that could be present in foods, consumer goods, or treated drinking water, led to multiple, measurable differences in the normal microbial community that inhabits the human gut. The changes observed in microbial metabolism and the gut microenvironment with exposure to nanoparticles could have implications for overall human health, as discussed in an article published in Environmental Engineering Science, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Environmental Engineering Science website until June 1, 2015.
The National Nanotechnology Initiative (NNI) today published the report from the workshop, "Stakeholder Perspectives on Perception, Assessment, and Management of the Potential Risks of Nanotechnology" (R3 Workshop), which was held September 10-11, 2013, in Washington, D.C.
The increased use of engineered nanoparticles (ENMs) in commercial and industrial applications is raising concern over the environmental and health effects of nanoparticles released into the water supply. A timely study that analyzes the ability of typical water pretreatment methods to remove titanium dioxide, the most commonly used ENM, is published in Environmental Engineering Science, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Environmental Engineering Science website until April 10, 2015.
Are cellulose nanocrystals harmful to human health? The answer might depend on the route of exposure, according to a review of the literature by a Virginia Tech scientist, but there have been few studies and many questions remain.
Dunkin' Brands, the parent company of the Dunkin' Donuts chain, has agreed to remove titanium dioxide, a whitening agent that is commonly a source of nanomaterials, from all powdered sugar used to make the company's donuts. As a result of this progress, the advocacy group As You Sow has withdrawn a shareholder proposal asking Dunkin' to assess and reduce the risks of using nanomaterials in its food products.
The National Institute of Standards and Technology (NIST) has issued a new silver nanoparticle reference material to support researchers studying potential environmental, health and safety risks associated with the nanoparticles, which are being incorporated in a growing number of consumer and industrial products for their antimicrobial properties. The new NIST test material is believed to be the first of its kind to stabilize the highly reactive silver particles in a freeze-dried, polymer coated, nanoparticle cake for long-term storage.
What do a human colon, septic tank, copper nanoparticles and zebrafish have in common? They were the key components used by researchers at the University of California, Riverside and UCLA to study the impact copper nanoparticles, which are found in everything from paint to cosmetics, have on organisms inadvertently exposed to them.
