Researchers from the National Institute for Occupational Safety and Health announced this week that preliminary results from a new study show that a particular type of carbon nanotube can “increase the risk of cancer in mice exposed to a known carcinogen.”
The findings, discussed in an agency blog post and during a presentation at […]
In a new study based on a simulated real-world environment, researchers have found that exposure to relatively low levels of super-small silver particles can cause problems within an ecosystem.
The study, published this week in the journal PLOS ONE, attempted to mimic the exposure plants and microorganisms might get to nanosilver, which is […]
A group of European scientists say they’ve discovered a way to ease the biggest fear about some types of carbon nanotubes by changing their chemistry and making them shorter.
If these new findings, published recently in Angewandte Chemie, hold up, they could resolve a central tension in the development of multi-walled carbon nanotubes. […]
With an eye on the ever-growing number of consumer products that contain ultra-tiny particles — the vast majority of which are totally unlabeled — the U.S. Environmental Protection Agency is teaming up with the Consumer Product Safety Commission to share information and cutting-edge research.
The two agencies announced the move this week, stressing […]
Chinese researchers have found that synthetic sweat of different pH levels prompts different types of releases from fabric infused with super-small nanosilver, adding intriguing new questions to the discussion over the potential environmental impact of this increasingly common substance.
The scientists created three types of artificial sweat: an acidic solution, an alkaline solution, and […]
A common home-building practice may expose workers to super-small particles carrying a standard flame retardant, according to a new study.
Scientists from Switzerland and China looked at two types of common polystyrene foam that’s often used to line the walls of buildings — and is also treated with brominated flame retardants to reduce fire […]
Noted: Environmental Health News has a good rundown of a paper released this summer that shows titanium dioxide nanoparticles — an increasingly common ingredient in sunscreens — can release free radicals after exposure to chlorine and sunlight.
These results add another layer to the running debate over the safety and efficacy of so-called […]
The European Commission has just issued a report about how to deal with vexing questions about super-small nanomaterials, at least in the short term.
The recommendation? Rely on the European Union’s chemical safety law, known as REACH, for most regulation of nanomaterials, and scrutinize these ultra-tiny substances on a case-by-case basis.
“In the light […]
Chinese officials are urging the country’s nanotechnology sector to take safety more seriously, according to a news report in the academic journal Nature.
Jane Qiu reports from the 6th Annual Conference on Nanotoxicology, which was held in Beijing earlier this month. She quotes the deputy director of the Chinese Academy of Sciences’ National […]
Researchers have long lamented the ubiquitous nature of plastic in the world’s oceans, from the murderous six-pack ring to the pulverized flotsam of toys. New research shows the tiniest of plastic particles could stunt mussel growth, opening a query about whether nano-sized remnants pose a risk to a wider swath of the marine world.
Researchers […]
