Nano-particles given health all-clear
- Health risk assessment for nanoparticles: A case for using expert judgment. Milind Kandlikar; Gurumurthy Ramachandran; Andrew Maynard; Barbara Murdock; William Toscano // Journal of Nanoparticle Research;Jan2007, Vol. 9 Issue 1, p137
Abstract??Uncertainties in conventional quantitative risk assessment typically relate to values of parameters in risk models. For many environmental contaminants, there is a lack of sufficient information about multiple components of the risk assessment framework. In such cases, the use of...
- Airborne engineered nanoparticles: Are they a health problem? Morawska, Lidia // Air Quality & Climate Change;Aug2010, Vol. 44 Issue 3, p18
This article focuses on airborne engineered nanoparticles generated in a growing number of commercial and research facilities. Despite their presence in the air of many such facilities, there are currently no established and validated measurement methods to detect them, characterise their...
- PHOSPHORUS & HALOGEN BASED FLAME RETARDANTS. Dombrowski, Ronald // Proceedings of the Annual International Conference & Exhibition ;2007, p92
The article provides information on phosphorus and halogen based flame retardants. Phosphorus flame retardants require bridging chemicals, such as dimythyloldihydroxyethyleneurea (DMDHEU) and trimethylol melamine, to make them a good wash durable flame retardant for cotton fabrics. It achieves...
- Silver nanoparticles used as Glass Wool Fibers' Coating. // Paintindia;Sep2010, Vol. 60 Issue 9, p145
The article reports on a cost-effective method of coating glass wool fibers using silver nanoparticles proposed by researchers at Sharif University of Technology in Iran.
- Chemical characterization of engineered nanoparticles. Winchester, Michael R.; Sturgeon, Ralph E.; Costa-Fernández, José Manuel // Analytical & Bioanalytical Chemistry;Feb2010, Vol. 396 Issue 3, p951
The authors discuss the increased interest of researchers in the engineered nanoparticles nanotubes and nanorods. They claim that although engineered nanoparticles are technically not nanoparticles, they are being studied and developed for various technological applications. The authors reveal...

- State of the art in human risk assessment of silver compounds in consumer products: a conference report on silver and nanosilver held at the BfR in 2012. Schäfer, Bernd; Brocke, Jochen vom; Epp, Astrid; Götz, Mario; Herzberg, Frank; Kneuer, Carsten; Sommer, Yasmin; Tentschert, Jutta; Noll, Matthias; Günther, Isabel; Banasiak, Ursula; Böl, Gaby-Fleur; Lampen, Alfonso; Luch, Andreas; Hensel, Andreas // Archives of Toxicology;Dec2013, Vol. 87 Issue 12, p2249
In light of the broad spectrum of products containing nanosilver, the harmfulness of nanosilver to human health and the environment was intensively discussed at a conference held in February 2012 at the BfR. The conference agenda covered the aspects of analytics of nanosilver materials, human...

- A Novel Size-Selective Airborne Particle Size Fractionating Instrument for Health Risk Evaluation. GORBUNOV, B.; PRIEST, N. D.; MUIR, R. B.; JACKSON, P. R.; GNEWUCH, H. // Annals of Occupational Hygiene;Apr2009, Vol. 53 Issue 3, p225
Health risks associated with the inhalation of airborne particles are known to be influenced by particle size. Studies have shown that certain nanoparticles, with diameters <100 nm, have increased toxicity relative to larger particles of the same substance. A reliable, size-resolving sampler...
